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. 

Cape May Warbler (Setophaga tigrina) banded at the USGS Bird Banding Lab during fall migration.

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.

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.

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.

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.
