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!

What a treat! The banding team catches a Warbling Vireo once every couple of years. This individual was banded on September 15th. They get their name from the varied, burbling, fast-paced song that the males produce.

Scientists at the Fall Migration Station look for clues to identify whether an individual is a male or female to determine the demographics of a population. In Magnolia Warblers looking at the white spots in the tail is a good clue. The large square tail spots, like the one pictured, indicate this is a male Magnolia Warbler.

Despite being a hard bird to find in the field for many birders, the Fall Migration Station team successfully sees multiple Connecticut Warblers each year, as they utilize the shrubby habitat under the powerlines.
