This American Redstart is one of the more common species, out of the total 33 warbler species, the Bird Banding Lab has banded at the Fall Migration Station at Patuxent Research Refuge.

Scientists can use clues in the wing to age birds. In this case the bird has molted all its wing feathers recently, so it is an after hatch year male. 

This female Rose-breasted Grosbeak was one out of six grosbeaks banded at the Bird Banding Lab's Fall Migration Station. Making it an irruption year at the station.

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

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.
