2011 - Preseason News
MMP has lots of BIG NEWS heading into the 2011 season. First and foremost Mark Garland
has officially joined Team Monarch as our Communication Director. For many of you Mark will need no introduction but briefly Mark is a naturalist par excellence with a long list of credits and titles including author, tour leader, researcher, and teacher. Besides the numerous hours he has volunteered for MMP, he has worked for the National Park Service, the Audubon Naturalist Society, and New Jersey Audubon's Cape May Bird Observatory. We welcome Mark with open arms (in fact we are not sure what we would do without him)!
One of the projects in which Mark Garland has had an integral part and one that directly benefits MMP's bottom line is the World Series of Birding: Monarchists. This extraordinary group of Cape May field naturalists has for several years applied their talents as birders in the service of monarchs. For more on the Monarchists and their awesome efforts see Mark's web page at:
Monarchists: World Series of Birding 2011
Mike Crewe, CMBO's Program Director, will be working with MMP as well. Mike's list of credits is as long as your arm but we are particularly pleased he is passionate about insects. His interest in "bugs" insures that we have a man on the inside at CMBO.
Last but not least we are fortunate to have Rebecca Allmond and Tori Pocius working with us this season. Rebecca has worked with a variety of invertebrates including the endangered Karner Blue Butterfly and a native Hawaiian damselfly. Tori has an interest in Monarch biochemistry and has been involved with research focusing on milkweeds and
the OE parasite.
2010
After a very slow 2009 season Team Monarch had high hopes for this fall's flight. Jenny Howard this year's MMP Field technician observed an average of 26.01 monarchs per hour on the first week of our road census. As we were redoubling our efforts to strengthen our ties with CMBO, we were pleased to be working with Don Freiday, a NJ Audubon staffer with an active interest in monarchs and our research in particular.
While week #2 saw an increase in migrant monarchs through Cape May, an orange blizzard hit in the middle of week #3. Even by historic standards this was a huge flight. On the 3 road census runs on September 18th Jenny Howard and Michael O’Brien recorded 1592 monarchs in a total of 60 minutes of observation! Those of us (including yours truly) who were not in Cape May for this flight were hopeful for a repeat performance later in the season.
While we didn't have a flight to match week #3 we did have a steady flow of monarchs throughout most of the season. Jenny was a star of our State Park workshops and was making plans to head for the Bahamas to study Kirtland’s warblers this winter. Many thanks to Jenny and special thanks to Louise Zemaitis, our field director, as well as the many volunteers whose efforts kept our project running smoothly throughout September and October.
Finally, and at the risk of beating my own drum, I’m pleased to announce that Monarch Net has honored our project and yours truly with their “citizen-scientist” salute. Details on their website at:

2009
As the numbers show, 2009 was a slow year for monarchs. But anyone who
has visited Cape May Point in fall knows that one day can make a season. A flood of accipiters in the morning, a dragonfly push at mid-day and monarchs by the dozens coming to roost in the evening light. And yes, we had a few
days just like that in 2009. Everyone on Team Monarch waits for those days and the old hands have been blessed by many.
For me, one thing that adds to the pleasure of these "perfect days" is to be with someone experiencing the magic for the first time. And Claire Iseton, our research intern for 2009, was not shy about expressing her excitement about monarchs and merlins! While this was Claire's first fall in Cape May, her undergraduate studies and previous research had focused on migration - not monarchs but sea turtles. And it was not long after Claire began helping out with our demos that she adroitly included some facts about these ocean-going migrants. With Claire's permission I am sharing here a few of her words - words that express both her enthusiasm for Cape May and the
value of her experience with MMP.
The season has ended and I find myself wishing that there were more Monarchs for me to chase around the Point. This . . . has been one of the most valuable work experiences I have had in my post-undergraduate career. My work here in Cape May has strengthened my career goal to work with migratory species and left me with a now blossoming interest in insects and birds. Thank you for providing such an incredible opportunity this fall and for treating me like a member of the family.
After returning to her home in Texas we received this - So far I haven't found any Monarchs to tag down here, but there's been a lot of Mexican Silverspots to look at.Thanks again for lending your butterfly books out while I was there, I definitely have a whole new appreciation for all the really cool butterflies (and birds) you can see here.
Just weeks before the start of the 2010 MMP season Claire wrote to share some news -
Things have been very busy down here in Texas - I wrapped up my work with the Park Service at the end of Sept. and because of a chance meeting this January with a Post-Doc researcher I will be heading into graduate school next year at Texas A&M at Galveston with funding! The birding and butterfly watching here has been amazing . . . I've seen a TON of Monarchs and Queens and gotten a bunch of life birds. Lots of fun spiders down here as well - not as many jumpers as I would like, but all the fun to look at!
I think it's fair to say Claire is well on her way to bigger and better things. We are proud she spent a fall with us and it is clear she left us with a bit of Cape May magic in her back pocket.

2008
Although we often think about the Monarch Monitoring Project in terms of census data
and numbers of monarchs tagged or recaptured, the project exists because of the dedication,
cooperation, and enthusiasm of our workers. No one exemplified these passions better
than George Myers. George passed away on August 13, 2008 - just weeks before the beginning of
the monarch season. George worked with us for over a decade and always with extraordinary
good humor as well as a shining smile. We dedicate the 2008 MMP season to our friend George Myers.
We will miss you George.
While the number of monarchs passing through Cape May was below average (see, at bottom) in 2008, we were pleased to learn
just prior to the beginning of the 2009 season that 7 of "our" monarchs (all tagged in
Cape May Point, NJ) made it to Mexico. Here is
the list as reported by Louise Zemaitis.
- LAE 184 - female, tagged by Erin Cord - 9/24/08
- LAA 536 - male, tagged by Paige Cunningham - 10/3/08
- LAA 563 - male, tagged by Paige Cunningham - 10/4/08
- LAG 439 - female, tagged by Patsy Eickelberg - 10/4/08
- LAE 621 - male, tagged by Erin Cord - 10/5/08
- LAA 921 - female, tagged by Patsy Eickelberg - 10/8/08
- LAG 439 - female, tagged by Patsy Eickelberg - 10/4/08

2007
While it didn't compare with last season's deluge of monarchs, the 2007
migration showed more or less average numbers of monarchs passing through Cape May. As is
often the case, it is well after the season is over before we know about many
of our successes. Recaptures of monarchs tagged in Cape May by MMP workers included
two individuals in Florida, one in Apalachacola and one in El Joben. To date two monarchs
tagged in 2007 have been recaptured in Mexico - one was tagged by Louise Zemaitas and one by
Bradley Smith. Louise and Bradley, the MMP's first mother and son team, added a special flavor
to this year's work.
Speaking of Bradley, it reminds me of how time flies! Over two decades ago I met this
budding naturalist (and his mom!) on a bird walk at Higbee Beach. Fortunately for us Brad focused a
good deal of his talent and attention on insects. His official position as MMP Intern this year was not
only a boon to our project but it also reminded us of the importance of the "next" generation.
If we are successful in passing along our passion for monarchs to naturalists just beginning their
careers we will have done our job well.

2006
The 2006 monarch flight was second only to the monster flight of 1999
and the numbers are reflected in our road census data.
The peak of the migration occurred on September 25 (1884.21 Monarchs per
hour), September 26 (2201.79), and October 3 (1537.50). These flights
were reminiscent of seasons past when there were so many Monarchs that
the Seaside Goldenrod in the dunes turned orange and black. We also
observed a number of large roost sites in Cape May and Stone Harbor
Point.
Over 4000 Monarchs were tagged in 2006. We received word that one of
our Monarchs en route - Monarch #161177 tagged by Dianne Newman on
October 2 was found alive at Folly Beach, Charleston County, South
Carolina on October 13. That's about 545 miles from Bill and Edie
Schuhl's garden in Cape May Point where it was tagged. An average of 50
miles per day!
We also recorded five more recoveries of MMP
tagged Monarchs from the Mexican winter roosts. Dozens of volunteers and
donors support our work each year. We thank each of them. Major funding for the
Monarch Monitoring Project continues through the generous support of
Beth Van Vleck.

2005
The 2005 season was a "bounce back" season for the monarchs at Cape May.
After several "down" years monarchs showed up in good numbers and kept
us busy late into the season. Ordinarily our biggest pushes come in
September and early October. This year the largest flights of the fall
were on October 17, 18, and 19. The October 18th census runs averaged
over 896 Monarchs per hour - our latest "big day" to date.
Each year Monarch Monitoring Project efforts are bolstered by the
courtesy of several very special Cape May Point residents. Their
landscaping efforts have resulted in gardens and shrubs that act as
magnets to migrating monarchs. The monarchs benefit from these important
nectar sources, using them to fuel-up for their epic migration. MMP
staff and volunteers benefit too, as these special yards provide ideal
places for us to conduct tagging activities. The property owners have
invited us into their yards and gardens, often with a smile and a
friendly wave. We appreciate the courtesy of these kind folks and want
them to know that they play a very special part in the Monarch
Monitoring Project.

2004
The 2004 season was a portrait of both our hopes and our fears. After
two below average seasons (2002 and 2003) Monarch researchers were
hopeful that numbers of migrants would rebound and that once again Cape
May would play host to multitudes of monarchs. Unfortunately, when the
final census run was complete and the numbers were tallied, average
numbers of monarchs observed per day set a record low for the history of
our census (see table below). A paper (in press) by Walton, Brower, and
Davis analyzing the census shows that previous periods of one or two
down years have always been followed by a rebound in monarch numbers. We
now have data for a 3 year down turn in migrant populations and will be
paying particularly close attention to monarch numbers in 2005.
On the brighter side Paige Cunningham, our seasonal field technician,
hosted an ever increasing number of scheduled monarch demonstrations and
improptu tagging sessions. Interest in Monarch butterflies has never
been greater and Paige along with other members of Team Monarch talked
with hundreds of adults and children about the lives of monarchs and the
plight of the migratory generation. Lu Ann Daniels (pictured right), a
perennial MMP volunteer, conserves gas as she tags monarchs.

2003
The 2003 migration reminded us more than ever that the weather is always the greatest influence of what we see here in Cape May. The monarch flight serves as an excellent barometer. It started off with a nice burst of activity with an early September cold front, was hampered by two hurricanes and easterly winds through most of the month, and then went through a period of steady activity with successive cold fronts.
So wrote Louise Zemaitis in her summary of the 2003 season for the Peregrine Observer - The Journal of the Cape May Bird Observatory. Louise has worked for the MMP since its inception. Besides her perennial job as MMP coordinator Louise has also plied her talents as researcher, educator, artist, author and cheerleader. Much of our success is due to Louise's heroic efforts. Yea Louise!! The Monarch Monitoring Project depends on dedicated workers and volunteers with a love of nature in general and a special place in their heart for the monarch butterfly. The 2003 team included Christine Austin - MMP field technician and research assistants Michael O'Brien, Patsy Eickelberg, LuAnn Tracy, Mark Garland, and Paige Cunningham. Additional field assistance was lent by Chris Kisiel, Tony Leukering, George Myers, and Bill and Edie Schuhl.

2002
Although the ultimate impact of last winters massive kill (see summary
above) on the Mexican over-wintering grounds was less dire than some had
projected, the number of monarchs recorded on our Road Census this fall
was below average (see table below). While monarch numbers were down MMP
workers were as busy as ever during September and October. A total of
3,760 Monarchs were tagged by MMP coordinator Louise Zemaitis, MMP field
technician Janine McCabe, and research assistants Michael O'Brien, Patsy
Eickelberg, LuAnn Tracy, Mark Garland, and Bradley Smith. Additional
field assistance was lent by Paige Cunningham, Chris Kisiel, Steve
Rodan, Bill Schuhl, and Edie Schuhl. Tagging efforts have been well
rewarded during the last several years as indicated by last year's
recoveries (16 and still counting) from Mexico.
Chris Kisiel, our 2001 field technician, continued her work on monarchs
as an assistant to Dr. Lincoln Brower. Chris' work included laboratory
analysis of monarch biochemistry and a trip to Mexico where she helped
in the evaluation of monarch mortality at the over-wintering sights. Go
Chris!

2001
Led by the efforts of
coordinator Louise Zemaitis and field technician Chris Kisiel (see image right -
Chris in a bed of Monarchs), "Team
Monarch" had a very successful 2001 season. Total numbers of Monarchs
were up and this provided excellent opportunities for education and
research. In all, 6,831 Monarchs were tagged and 5 of these were
recaptured in Mexico. On our busiest days we were ably assisted by
Michael O'Brien, Patsy Eickelberg, and LuAnn Tracy along with a bevy of
other Monarch aficianados. Under the guidance of CMBO's David Mizrahi
studies were initiated to assess the energetic condition of migrant
Monarchs throughout the season. Thanks to funding from Bushnell sports
Optics and Ann Louise Mapes through the Jodi Paterno Memorial Fund
hundreds of Monarchs were captured, weighed & measured, and released.
These data will be analyzed over time and should yield insights into the
overall fitness of the migrants.
Perhaps the most significant recent chapter in the drama of the
Monarch butterfly came from the Mexican over-wintering grounds. In
mid-January two days of rain followed by a cold snap resulted in a
massive Monarch kill. Professor Lincoln Brower, our chief research
advisor, was in Mexico shortly after the event. Lincoln's research
indicates that approximately 265 million Monarchs died at the Chincua
(Zapatero) and Rosario (Conejos) colonies. This amounts to 75-80% of the
overwintering Monarchs. Although the ultimate affect on Monarch
populations is not yet known, such events are best evaluated by ongoing
sampling research such as that conducted by the Monarch Monitoring
Project at Cape May. Details of the January Monarch kill will be
published by Brower, Garcia, Kurst, and Rendon in an upcoming volume.

2000
Following one of the more
spectacular Monarch migrations in memory, the 2000 Monarch migration was
a mere shadow of the movement seen through Cape May in 1999. The reasons
for this change are unclear, but long term studies such as the Monarch
Monitoring Project should provide some of the answers. MMP coordinator
Louise Zemaitis and intern Jodi Paterno led the "Team Monarch" effort
this year with notable assistance from Michael O'Brien and Gayle Steffy.
Additional support was lent by Bonnie Smith, Jane Kashlak, and Renee
Crouse. A total of 4,646 Monarchs were tagged by various members of the
crew and to date recoveries have been reported from Maryland, Virginia,
North Carolina and Mexico! A highlight for the season was Dr. Lincoln
Brower's visit to Cape May. Dr. Brower has been a leading force in the
MMP since it's inception in 1990. Besides participating in tagging and
censusing activities, Lincoln gave 2 "standing room only" lectures to
monarch enthusiasts who were lucky enough to be in the area during his
visit.
I think the saying goes - the brighter the flame, the quicker it burns. It is always most difficult when it's one of your own flames that no longer burns brightly. On February 9, 2001, Jodi Paterno, CMBO's 2000 Monarch Monitoring Project intern, died in an automobile accident near Eugene, Oregon. Jodi was a free-spirited young woman who had a boundless lust for life and a tremendous reverence for nature. We will always fondly remember Jodi running barefoot around Cape May Point, swinging her butterfly net. Although we didn't know her long, we all felt we knew her well. She touched everyone she met, and the memory of her vitality is kindled in all of us.

1999
The 1999 MMP season
was, in a word, fantastic! Louise Zemaitis directed operations and was
ably assisted by MMP intern Meghan Walker. While the first two weeks of
September seemed normal, the third week of the census saw the arrival of
the leading edge of an avalanche of monarchs. The period from
mid-September through mid-October 2000 shattered all previous records
for sheer numbers of monarchs observed passing though Cape May. Chris
Wood, CMBO's official Seawatch counter in Avalon counted 44,281 monarchs
streaming by his observation point on October 1st. On October 2nd 2,836
monarchs were counted on the 3 census runs as an estimated quarter of a
million monarchs moved through the area! Louise and Meghan, assisited by
Michael O'Brien, Gayle Steffy, and Jim Dowdell were also busy with
tagging activities. The team tagged a total of 5,384 monarchs during the
fall season. As a result of these efforts 6 of our
tagged monarchs were recovered in Mexico at the El Rosario site.
Monarch #182784, tagged and released by Meghan in Cape May at 1:00 PM on October 6 was recovered by Mark Garland on Fisherman's Island, VA the following day at 5:00 PM. The 2000 MMP season at Cape May established a number of bench marks for our project and we are looking forward to the new millenium.

1998
Early predictions for 1998 monarch migration were pessimistic.
Several factors, including extremely dry conditions in the Mexican
over-wintering grounds and a relatively wet early summer along with dry
conditions during July and August in the monarch's northeastern breeding
range did not bode well. Early September seemed to realize these
predictions as few monarchs were seen in Cape May. Although there was a
small wave of monarchs on September 11th and 12th, we were to wait until
the last week of the month for the next substantial and sustained
flight. The action continued through early October but thereafter slowed
to a trickle, interspersed with several mid-October pushes. Below
average seasonal totals for our 3 times a day census runs reflect a
rather thin season.
| #Census Runs | Total Monarchs | Hours of Observation | Avg. Monarch/Hour |
|---|---|---|---|
| 167 | 2350 | 48.05 | 46.82 |
Tagging activities were definitely the highlight of the season. Larissa Smith, MMP's 1998 research intern, along with Louise Zemaitis, Michael O'Brien, and Dick Walton caught and tagged over 7,000 monarchs! All our worked paid off when 7 of our tagged monarchs were recovered at the El Rosario site in Mexico. These are the first Mexican recoveries for the MMP and the first substantial indication that East coast monarchs do indeed winter at the Mexican wintering sites. Another exciting development this fall was Mark Garland's pilot project in Cape Charles, Virginia. Designed after the MMP, Garland evaluated the possibilities of another site for similar research. Concentrations of migrants were particularly heavy at Kiptopeke State Park and it was here that Mark recovered 4 monarchs tagged at Cape May Point.
1997
The 1997 fall monach migration was, in a word, spectacular! And once
again NJAS/CMBO's Monarch Monitoring Project was in full swing. MMP
researchers conducting the Sepetember-October daily census counted 5,628
monarchs during 186 runs along the 5 mile route. A season total of 106
monarchs per hour of observation was the highest average since 1991.
Elizabeth Hunter, MMP's intern, tagged over 4,000 monarchs including
monarch # 104780 that, amazingly, was recaptured in the Bahama Islands.
This ranks right up there with hen's teeth and dinosaur eggs on the
rarity scale.
| #Census Runs | Total Monarchs | Hours of Observation | Avg. Monarch/Hour |
|---|---|---|---|
| 186 | 5628 | 48.02 | 106.61 |
Those folks lucky enough to have been in the Cape May area on either September 19th or 26th were treated to a blizzard of monarchs. In fact, on the 26th, 652 monarchs were counted on the 3 census runs. This eclipsed all previous records for daily census run totals. Observers at the Hawk Watch, Higbees, Cape May Meadows, and even along the streets of downtown Cape May reported hundreds, even thousands of monarchs on both of these days.
1996
MMANA continued
to strengthen its program in 1995. With financial support from The
Wildlife Conservation Society and CMBO, we began discussions with New
Jersey Audubon Society with the goal of making our Monarch research and
education efforts a permanent program under their auspices. Both Pete
Dunne, Director of CMBO and Joan Walsh, CMBO Research Coordinator were
involved. And we continued our "meat and potatoes" programs of
censusing, tagging, and "Butterfly Walks and Monarch Talks." A
serendipitous renaissance in butterflies and butterfly watching over the
last several years had swelled the numbers of folks attending our
programs. We were now hosting scores of interested adults and children.
Monarch numbers for the season were relatively low, however, and
although we had a slight push on the 18th of September, we waited in
vain for the "big 19."

1995
This was to be a
watershed year. Thanks to the efforts of Pete Dunne and the staff of
CMBO, MMANA - henceforth to be called the Monarch Monitoring Project
(MMP), officially joined the New Jersey Audubon Society. CMBO
educational and administrative resources strengthen all of MMP's
programs while giving the project a permanent home base. An important
initial move was CMBO's funding of a research intern position. And boy
did we find an intern! Gayle Steffy, a veteran Monarch tagger from
Lancaster Co., PA arrived on September 1st and stayed the season.
Gayle's quiet manner and an early season dearth of Monarchs had some
wondering just how she would do when the Monachs hit. Not to worry. When
the first big wave rolled into Cape May on September 19th (there's that
day again!) Gayle not only got excited, she got tagging. For the next 6
weeks it was hard to discern the blur of tags, nets, nimble fingers, and
record sheets that was Gayle Steffy. When the dust settled Gayle had
tagged over 5000 Monarchs including 501 Monarchs tagged on September
30th. All in all the 1996 Monarch season was a great success - a new
beginning offering great promise for things to come.

1994
Monarch activity began early in 1994. Spring brought a handful of very
early Monarch reports. In southern New Jersey Pat Sutton documented
various sightings between April 11 and April 21 including 15 Monarchs
seen in the Wildwood marshes on the 18th. Monarchs were also relatively
numerous in the Northeast during the breeding season as reported on the
summer Xerces/NABA Butterfly Counts. MMANA workers had good reason to
anticipate a strong fall flight. And on September 19th we set a new
record for a single day Monarchs count on our census runs. Three passes
along the 5 mile route yielded 456 Monarchs! And we had begun to notice
something special about September 19th. There seemed to be a fairly
consistent peak of Monarch activity on this date in Cape May each fall.
Because big Monarch flights are typically associated with the passage of
cold fronts, weather plays a part in this timing but the September 19th
"big day" appears to be fairly reliable.

| 148 | 4103 | 42.1 | 86.30 |
The highlight for the season actually occurred in November - long after the Monarchs had passed through Cape May. On November 18th Ed Maas of Temple Texas found one of "our" tagged monarchs in his yard. This was our first long distance return! The Monarch had been tagged on September 19th by our tagging team which included Louise, Brad and Alec (Louise's sons and budding naturalists), and myself.
1993
The 1993 season began on a several positive notes. Thanks to the
continuing cooperation and support of Lincoln Brower, MMANA received a
sizable grant from the The Wildlife Conservation Society (New York
Zoological Society). Our affiliation with New Jersey Audubon Society was
also strengthened as Louise Zemaitis, a CMBO staffer, joined MMANA as
Research Assistant.
Actually, Louise has helped with MMANA since its inception applying her talents as artist, tagger, and teacher. Another innovation for 1993 was our affiliation with Global Lab. Students from 6 schools in the U.S and Mexico participated in a pilot project focusing on the topic of animal migration. As part of their studies students were linked via e-mail with MMANA researchers in Cape May. Daily numbers from our census were relayed to students for interpretation and discussion. Vince Elia, another CMBO staffer, also joined the MMANA team and carried out a series of cross-Delaware Bay censuses. Using the Cape May to Lewes, Delaware ferry Vince confirmed that monarchs do indeed cross the Bay and sometimes in large numbers. On September 23 Vince recorded 134 Monarchs on his round trip census. MMANA workers also had time to tag nearly 1,000 Monarchs. Finally, we continued our all important census. Results are in the following chart.
| #Census Runs | Total Monarchs | Hours of Observation | Avg. Monarch/Hour |

| 145 | 2857 | 40.9 | 62.90 |
1992
By the fall of 1992 MMANA workers were better organized and ready to
put in their first full season. Based on the previous years experience,
we established a single, 5-mile census route running from Higbee Beach
to the end of Alexander Ave. on Cape May Point (see graphic).
The route would be run 3 times a day from September 1st. through October
31st. Monarchs were counted along the route by a single observer driving
approximately 25 miles per hour. No stops were allowed to count specific
concentrations of butterflies. Monarch totals, starting and elapsed
times, and local weather conditions were recorded on each census. While
we may have been better prepared, the Monarchs were engaged in a
"no show." Actually, a severe winter kill at the Mexican over-wintering
sites the previous February had resulted in very low numbers on the
Northeastern breeding grounds. While it was instructive to document the
correspondence in low numbers of summer residents and fall migrants, the
census run seemed, at times, much longer than 5 miles. We kept busy,
however, with various educational programs including several "Butterfly
Walks and Monarch Talks" given at the CMPSP. Fortunately for us, the
Monarch is one of those critters that just naturally draws a crowd.
While not everyone can warm up to a fall-plumaged Bay-breasted Warbler,
it's hard to find a soul that isn't fascinated by Monarchs. And promise
a tagging demonstration - "You're going to put a tag on that little
thing and then expect it to fly to Mexico???" - and you need crowd
control! MMANA workers also spread the word about Monarch conservation
through interviews with The New York Times and The
Philadelphia Inquirer. And we kept on counting . . . But in the end,
our Newsletter summarized the season in its opening sentence -
"The 1992 fall migration of monarchs along the East coast was, in a
word, dismal."

After much preparation the Monarch Migration Association of North
America (MMANA) came into being in early 1991. By the fall we had data
sheets and methodologies ready for trial. Even more importantly we had
the support of the Cape May Bird Observatory and its Director, Paul
Kelinger as well as numerous individuals interested in monarch
conservation. Our goals for the fall were to establish census routes and
point counts in order to begin building a data base of monarch migration
though Cape May. And WOW did we have monarchs to count. 1991 turned out
to be a banner year for monarchs along the Atlantic coast. With help
from fellow researcher Greg Dodge we counted and we counted. The
following table presents the data for our census route(s).
| #Census Runs | Total Monarchs | Hours of Observation | Avg. Monarch/Hour |
|---|---|---|---|
| 93 | 1759 | 11.5 | 142.20 |
BEGINNINGS
On October 10th, 1982 I visited Cape May, New Jersey. Like scores of other birders before and since, I was there to witness the legendary hawk migration. I was not disappointed. My journal entry for the day includes the following:
. . . the Peregrines were truly impressive - overhead, at eye level, stooping, close in and far off . . . the accipiters filled the sky . . . our most spectacular birds were at Higbee Beach around the time the front passed through (where) there were Sharpies and Cooper's Hawks zipping through the coastal forest and up over the dunes, soaring, chasing, flapping and gliding.
On that day alone, the hawk watcher at Cape May Point recorded
62 Cooper's Hawks, 2,622 Sharp-shinned Hawks, 50 Peregrines, and 130
Merlin! It was not the birds, however, that began what has become an
annual passion. The next line in my journal says:
All day long we witnessed a phenomenal Monarch migration. The butterflies were as constant and continuous as the hawks.
During the ensuing 7 years I visited Cape May several times, always anticipating both the monarchs and the hawks. In the fall of 1990 I decided to spend 2 weeks in Cape May with the idea of planning a long-term research project on Monarch migration (what the heck - somebody has to do the work). I tried out several census methodologies at various places on Cape May Point. At Sunset Beach on September 27th in 8- one minute observation periods I counted 618 monarchs for an average of 77 monarchs per minute. The following day I counted over 1,000 monarchs streaming through Cape May Point State Park (CMPSP). Although there were plenty of monarchs, there were also many puzzles. One of my first discoveries, while counting Monarchs at CMPSP, was that the direction of the migratory flight seemed to reverse itself for no apparent reason. At one point a steady stream of Monarchs would be heading Southwest and then, within the space of 10 minutes, the whole flight would be going Northeast! When I returned home I puzzled over the data and even though there were more questions than answers, I was convinced Cape May would be an ideal site for my study. So . . . I wrote Lincoln Brower in December and we began discussions about setting up the project.
Imagine an insect weighing less than a paper clip beginning a journey in Scarborough, Maine in late August. If successful she will arrive at her over-wintering grounds high in the Sierra Madre Mountains in Michoacan, Mexico in October. Our monarch will have traveled well over 2500 miles.
The Monarch Monitoring Project's (MMP) overall goal is to increase our understanding of the fall migration of monarchs along the Atlantic coast. Both research and public education play their parts. Ultimately it is our hope that these efforts will improve the lot of these marvelous butterflies so that populations of migrant monarchs will enjoy a secure future. Details on our research and educational efforts are in the next three tabs.
We look forward to seeing you in Cape May this fall. Contact CMBO for a schedule of our tagging demos.

The Cape May Point Road Census is conducted three times per day from September 1st through October 31st. Rather than trying to count all the monarchs moving through Cape May, our methodology uses sampling criteria which result in data reflecting relative annual numbers. Counts are made by a single observer driving a car approximately 20-25 mi. per hour along a 5 mile route. All monarchs observed are tallied but no stops are allowed to count specific concentrations. The route passes through a variety of habitats including southern hardwood forest, agricultural field, brackish wetland meadow, suburban neighborhoods, and coastal dunes along the Atlantic Ocean and Delaware Bay. Annual summaries on this page include yearly data for the Road Census. Details of data, graphs, and analysis are on our site.
One of the great natural history mysteries of the 20th century was finally solved in 1975. Working in collaboration with Fred and Norah Urquhart, Ken and Cathy Brugger "discovered" the over-wintering site for monarch butterflies high in the mountains of central Mexico.
During the ensuing two decades our knowledge about the migration of monarchs grew by leaps and bounds as researchers, including Lincoln Brower, added new pieces to the puzzle. In the early 1990s, however, opinions differed as to where the Atlantic coast migrants over-wintered. Urquhart suggested this group might be "aberrant," moving south along the Florida peninsula ultimately over-wintering in the Yucatan or some other unknown location to the south. In 1991 when the MMP began field work many of us assumed the Atlantic coast fall migrants over-wintered in Mexico. An early goal of the MMP was to settle this debate.
Although MMP workers initially tagged less than 1000 monarchs per season, a 1994 MMP tagged monarch recovered in Temple, Texas pointed towards the Mexican hypothesis. In 1995 Gayle Steffy, our research intern and veteran monarch worker, set new benchmarks for our efforts by tagging over 5000 monarchs.
Following Gayle's lead, we redoubled our tagging efforts in susequent years. The payoff came in 1998 when 7 of our tagged monarchs were recovered at the El Rosario site in Mexico. Details of MMP recaptures both along the migratory route as well as in Mexico are on the
Education has always been an important part of the MMP. A newsletter, first issued with our original name (see above), was our initial endeavor.
Perhaps our most popular programs are the informational sessions we offer at Cape May Point State Park. Cape May in fall is a popular destination - naturalists, Elder Hostel groups, Victorian Week participants, and even those coming to the annual Lima Bean Festival are all a draw. MMP staff and volunteers talk to literally thousands of these visitors each year sharing the basics of monarch biology and conservation and (everybody's favorite) conduct tagging demos. Please join us and help tag a monarch! Check with CMBO for this fall's schedule.
MMP staff also work with students from local public schools in Cape May and Stone Harbor as well as with several private school groups. Another educational aspect of MMP efforts is our data sharing with other research and educational projects. Included among these are Monarch Watch and Journey North.
Publications are an important piece of our educational work. MMP staff have written popular articles for American Butterflies and CMBO's Peregrine Observer. Our project has also been the focus of articles in Journal of the Lepidopterists' Society, Annals of the Entomological Society of America, and Journal of the Kansas Entomological Society. And in 2006 we produced the DVD Cape May - Fall Flight.
