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!

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.

At the Bird Banding Lab's Fall Migration Station, Winter Wrens are one of the smallest species they band. They have the smallest tail measurement at the station, between 26-36 millimeters!
