The Science and Research Committee was established to provide review of the Project’s ongoing banding efforts and to search out new research initiatives. The committee is interested in developing relationships with researchers who would benefit from hands-on access to migrating raptors. Interested individuals can contact us at capemayraptorbanding@gmail.com.

Raptor Feather Sampling – Our volunteer banders collected feather samples again in 2024.
We collected samples from over 200 raptors, including several from Sharp-shinned Hawks that
showed signs of Capillaria. The standard feathers will be shipped to the Biodiversity Research
Institute (BRI) for storage and analysis. In addition to the research done by BRI on mercury
content, the feathers will also be made available to others for related research. Pending
approval from our CMRBP Science and Research Committee, we may provide feather samples
from Sharp-shinned Hawks for the purpose of isotope analysis to determine region of natal
origin and several other purposes.
Feather Samples of Prey Items – Remnant feather samples from prey items were collected
from the talons and mouth area of six raptors in fall 2024 and will be forwarded to Dr. John
Delong at the University of Nebraska. Dr. Delong is conducting research on how migration
affects prey selection as the raptors move out of their home territories.

Assessing Heavy Metal Bioaccumulation and Stable Isotope Ratios in Feathers of
Migratory Raptors – This project continued for 2024. Dr. Baer, his students Colby-Sawyer
College and CMRBP banding volunteers collected feather samples for later analysis.

West Nile Virus and Eastern Equine Encephalitis incidence in migratory raptors – Dr. Nick
Baer and his students from Colby-Sawyer College, collected flat flies for research related to
avian pathogens. This project continued for 2024, with banders noting the presence of flat flies
on each trapped raptor, and when time permitted, counting the number of flat flies on each
trapped raptor.

Transmitter telemetry for Golden Eagles – Dr. Trish Miller, West Virginia University, assisted
by Mike Lanzone of Cellular Tracking Technologies, continued Dr. Miller’s project to band and
attach GPS telemetry units to Golden Eagles. Dr. Miller trapped a Golden Eagle November 20,
2017, and successfully attached a CTT transmitter to the eagle before release. Dr. Miller and
Mr. Lanzone hope to attach additional transmitters to Golden Eagles in the future to learn more
about movement ecology of coastal Golden Eagles and how they may differ from the
Appalachian Plateau wintering population.
No Golden Eagles were trapped in our fall 2024 season, so no CTT transmitters were applied.
Two previously trapped and equipped Golden Eagles, Loves Swan (trapped by John Shafer fall
2016) and Meadows (trapped by Dr. Trish Miller fall 2017), did not reconnect to the cellular grid
after spring of 2018 as they migrated north into eastern Canada.
To learn more about this research, please watch Dr. Miller’s presentation in our CMRBP Zoom
library. We will ask her for an update as well.

Capillaria in Sharp-shinned Hawks – This project continued for fall 2024 with an update: we
did not collect mouth swabs as in 2023 and collected feather samples only on a voluntary basis.
Project leader is Dr. David Mathiason. Banders participated by examining captured Sharp-
shinned Hawks (SSHA) for the presence of oral lesions/plaques and scoring the severity.

Movement ecology of raptors in eastern North America – This project continued for 2024. Project leader is Dr. Trish Miller and Co-leader is Michael Lanzone who live in Cape May. This project is specific to placing a transmitter on a Swainson’s Hawk (SWHA) or a Rough-legged Hawk (RLHA). Dr. Trish Miller agreed to apply a CTT transmitter to any Swainson’s Hawks we trapped, in order to track their fall migration and their spring return to their breeding areas. While we did trap a Swainson’s Hawk in 2024, Dr. Miller was not available to apply the transmitter.
Timing of stopover and use of habitat by migrant raptors in the southern New Jersey peninsula – this project was updated for fall 2024, adding Broad-winged Hawks to this transmitter project. Project Leader is Dr. Trish Miller and Co-leader is Michael Lanzone who live in Cape May. This project proposes to attach transmitters to Sharp-shinned Hawks, Cooper’s Hawks, Red-shouldered Hawks, Red-tailed Hawks and for 2024 includes Broad-winged Hawks.
Past Research Projects
Flight Kinematics: Dr. Suzanne Amador Kane of Haverford College filmed raptor take-off and maneuvering kinematics. For more information about Suzanne Amador Kane and her research…..click here. There is also an interesting YouTube video on her work here.
Assessing Body Condition of Migrating American Kestrels: CMRBP, Inc. provided historical data for Teresa Ely’s Master’s thesis research using body mass information to determine if lack of food availability reflected in body condition is a potential cause for the long term decline of the American Kestrel population.
Deterrence Effects of High Brightness Lights: In 2014 and 2015, researchers at Lite Enterprises, Inc., Donald Ronning, President, conducted research to assess the reactions of approaching Red-tailed hawks to newly developed high brightness lights. Preliminary feedback is positive and there are expectations that that the lights will prove to be an effective deterrent in areas such as airports, wind farms and more.
Possible Hen Harrier banded in Cape May: In the fall of 2010, Katy Duffy a long time bander with the Project, captured a harrier with unusual plumage, mass and physical measurements.
Male Kestrel Plumage: In 2010, the Project cooperated with Elizabeth Wommack from U.C. Berkley, on a study investigating correlation between genetic variation and plumage coloration in male American Kestrels (Falco sparverius). For more information about Elizabeth Wommack and the Bowie lab at U.C. Berkeley click here
Merlin Population Genetics Research: During the 2009 season, the Project cooperated with Dr. Joshua Hull on a molecular genetic investigation of morphological and genetic differentiation among the three subspecies of Merlin (Falco columbarius) to test whether there is a genetic east-west population division in North America.
Sharp-shinned Hawk Migration Counts: Nicholas Bolgiano studied and published a paper on: Were the declines in the Sharp-shinned hawk migration counts of the mid-80’s related to the Spruce Budworm population?
