A Black-billed Cuckoo is weighed in a plastic pill canister, so that researchers can better understand the fluctuation of weight gain and loss during migration.

Scientists examine the wing of this cuckoo looking for signs of feather wear to age this bird.

DOI partners celebrating a day of restoring native Blue Ridge sculpin to a stream in Catoctin Mountain Park, Maryland. The team includes researchers from the USGS Eastern Ecological Science Center, resource managers from the National Park Service, and wildlife videographers from the US Fish and Wildlife Service.

This photo shows a salamander stream survey. During these surveys, transects are run along a stream, and rocks are flipped to find and capture salamanders. Each captured salamander is placed in a bag to be identified and measured. Salamanders are released after the survey is complete.

This is the first Prothonotary Warbler since 2007 at the BBL's Fall Migration Station. 

To age and sex Magnolia Warbler's in the hand, scientists look for clues in the tail. These large square white patches are an excellent indication that this bird is an after hatch year, male Magnolia Warbler. 

In the fall of 2022, the BBL's Fall Migration Station had a surprising number of early migrants pass through the station at the end of August, including an abundance of Blue-gray Gnatcatchers. 

A beautiful, sunny day with blue skies at the Leetown trout pond while on a birding excursion with the Potomac Valley Audubon Society.  This trout pond plays an important role in the community and gives veterans and handicapped groups the chance to get outside and catch big trout!  It also provides nourishing trout to the resident  bald eagles.
