It’s just past dawn. You hear a weak, thin note from somewhere overhead. Your eyes catch sight of a small bird flying by rapidly. What was it?
Impossible, you say? Not for elite birders! Sure, you won’t catch
every field mark, and the sounds aren’t full songs or even familiar
chip notes. But experts combine knowledge of flight calls with
observations of shape, flight style, snippets of color pattern, and
a thorough understanding of seasonal migration patterns. CMBO
researchers will be utilizing all these skills as they conduct a
thorough, quantitative study of songbird migration. CMBO naturalists
will be on hand to point out birds, describe the research process,
and share some of the secrets of these difficult identification
challenges - called the “Cutting Edge of Birding” by Pete Dunne.
Many songbirds, particularly warblers, are nocturnal migrants.
However, in certain coastal areas such as Cape May, thousands of
songbirds make brief migratory flights just after sunrise following
fall cold fronts. What’s most fascinating about these morning
flights is that birds are not flying south as one would ex
pect.
They’re flying north! This morning flight phenomenon has caught the
attention of many birders and ornithologists over the years,
including Witmer Stone who referred to the massive northward
migration of flickers and smaller songbirds as one of the most
striking ornithological sights of the region.
Why morning flight occurs is still unclear. However, like other migration events in Cape May, songbird migration is weather dependent. On some days few birds are seen; on others, thousands may be counted. Exceptional flights in excess of 100,000 birds have been recorded (October 16, 1990 & October 18, 1995).
In recent years, ambitious birders have gathered at Higbee to sharpen their skills in what must be birding’s toughest challenge: the flight identification of fall warblers. In 2003, after several years of volunteer counts, CMBO institutionalized the morning flight count by making it part of our research agenda.
We’ve counted hawks and seabirds at Cape May for many years. These
counts have provided crucial information on changes in bird
populations. Conservation decisions are based on the data from these
counts. The Mornin
g Flight project is part of a groundbreaking study
that will allow us to monitor migrating songbirds.
Morning flight counts provide one bit of information. Our research team also uses sensitive weather radar to track the movements of migratory birds. A third study uses acoustical monitoring. Microphones pointed toward the sky actually record the nocturnal flight calls of migrating birds. The recorded calls are translated, resulting in solid data about what birds have migrated over designated sites.
This three-part study will help us examine the abundance, distribution, and species composition of the nocturnal flights. New Jersey Audubon Society’s Cape May Bird Observatory is the only organization in North America conducting this pioneering research.
The Cape May Morning Flight Project takes place from Sept. 1 through
Oct.
31, beginning at sunrise every day and continuing for four
hours. The location is the northwestern corner of the Higbee Beach
Wildlife Management Area.
Head to the west end of New England Road. Just before the parking lot at road’s end turn right onto an unpaved road. The Morning Flight Project is based at a small observation tower on the left side of this road.
Special ½-hour free programs are offered every Saturday and Sunday morning through the project period at 8:00 a.m.
Important support for the Cape May Morning Flight Project comes from Carl Zeiss Optical. Zeiss binoculars and spotting scopes have long been the optics of choice of expert birders in Cape May and around the world. Carl Zeiss Optical products are available at both Cape May Bird Observatory centers. Additional support comes from the generous contributions of visitors to the Morning Flight Project and from CMBO members.
