Prairie Warbler in the hand
In 2024, the long-term fall migration bird banding station at Patuxent Research Refuge had it's first Prairie Warbler since 2019!

Indigo Bunting wing molt
Scientists at the banding station collect population data, including age and sex. Due to color contrast, Indigo Bunting wings are a great example of the feather wear and replacement that scientists look at to age a bird. This male Indigo Bunting has 3 different feather ages, which tells us it was born last year.

Hooded Warbler in the hand
Hooded Warbler are a treat at the EESC Bird Banding Lab Fall Migration Station, as the station bands an average of two each fall. Based on data collected, the individual pictured hatched this year and is a male.

Observing osprey nest
USGS scientist observing an osprey nest. Use of a mirror pole allows the researcher to observe the nest from a boat without disturbing the nest. The image was taken during a USGS study of osprey (Pandion haliaetus) and their prey (menhaden (Brevoortia tyrannus), and other species of fish) in the middle and lower Chesapeake Bay and its tributaries.

Scientists perform necropsies on blue catfish
EESC research volunteers Sean Walsh, Lydia Reed and Lindsey Hartzell take organ and tissue samples from two blue catfish. The research is part of a study to determine PFAS levels in blue catfish.
