Stomach contents from a blue catfish (Ictalurus furcatus) caught in the Potomac River near Nanjemoy, Maryland in March 2024.  The contents of a blue catfish's stomach often include a variety of clams, crabs, mussels and fish.

Mitten crabs (Eriocheir sinensis) are medium-sized crabs with mitten-like claws. They live in freshwater but need saltwater to reproduce.

As part of a collaborative study, Dr. Shannon White (USGS EESC) works with partners from the University of Delaware and Delaware State University to count endangered Atlantic sturgeon in the Delaware River using side-scan sonar.

The House Finch pictured was quite the surprise at the BBL's Fall Migration Station at Patuxent Research Refuge in 2023. Despite being common feeder birds in Maryland, this is only the second House Finch banded at the Migration Station since the 1990s!

Field Sparrows, like the one pictured, are one of 15 different sparrow species that have been banded at the BBL's Fall Migration Station. 

A biologist gently extends the wing of a Blue-headed Vireo to look for clues on how old the bird is. During fall migration, scientists can generally determine if a bird was hatched during the current year or if the bird is older. They do this by looking at the general wear of the feathers, and if the bird has retained any of their plumage as a nestling.
