The extraordinary Purple Martin is North America’s largest swallow. It’s a beautifully iridescent colonial nester, with a distinctive liquid gurgling call. Purple martins were once a common sight in summer all over the East Coast of the United States, but their populations have significantly declined over the past half-century. In Maine, where they used to be found all over the state, they have experienced a precipitous 95 percent decline in the last 50 years: https://www.maine.gov/ifw/fish-wildlife/wildlife/species-information/birds/purple-martin-landlords.html There are now just a handful of active colonies in a few towns. Dr. Anna Forsman wants to better understand why that is the case.
The focus of her research at Colby College is understanding how birds, like purple martins, interact with bacteria, viruses, and parasites in their environments. She is also interested in how environmental factors like insect availability and climate affect immune system function in wild birds. Last year, the Pooper Snoopers community science project that she created, received fecal samples from over 200 Purple Martin colonies in the U.S., including the one established by York County Audubon along the Mousam River in Kennebunk. DNA analysis of these samples will reveal the insect diet composition of these birds from across their breeding range.
This program is provided by Wells Reserve partner, York County Audubon.
About the Presenter
Anna Forsman earned her doctorate in ecology and evolutionary biology at Cornell University. She studied Purple Martins for years through her postdoctoral work at the University of Central Florida (UCF), where she established the UCF Purple Martin Project. Three years ago, she joined the faculty of Colby College as an assistant professor of biology. She has studied cavity nesting birds for more than 20 years.
