These tiny balls of energy are sometimes referred to as mice with the way they scurry around the forest floor. During the breeding season, males will sing one of the more complex songs out of North American bird species. Each song lasts 5-10 seconds and consists of unique bubbly notes which the individual will combine and modify over time.  

One can really see how a Golden-crowned Kinglet got their name! This bird was handled and marked at the EESC Bird Banding Lab's Fall Migration Station. 

The sparrows pictured here represent the main sparrow species the EESC Bird Banding Lab’s Fall Migration Station sees each year. And last year, the White-throated Sparrow was the most numerous species banded at the station.

What’s so cool about this bird? Check out that large seed-cracking, grasshopper-chomping bill, that helps us ID this as a Blue Grosbeak. Based on its plumage, the banders were able to determine this bird was born this year and was caught in the same net as two other young Blue Grosbeaks.

In 2024, the long-term fall migration bird banding station at Patuxent Research Refuge had it's first Prairie Warbler since 2019!  

Scientists at the banding station collect population data, including age and sex. Due to color contrast, Indigo Bunting wings are a great example of the feather wear and replacement that scientists look at to age a bird. This male Indigo Bunting has 3 different feather ages, which tells us it was born last year.

Hooded Warbler are a treat at the EESC Bird Banding Lab Fall Migration Station, as the station bands an average of two each fall. Based on data collected, the individual pictured hatched this year and is a male.

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. 

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!

This Black-throated Green Warbler is one of 38 species of warbler banded at the EESC BBL’s Fall Migration Station.

This year the lab has recorded its second highest number of banded Cape-May Warblers, like the hatch-year male pictured here, since operations began at the Fall Migration Station in 1979. 

Brown Thrashers are one the larger species of passerine banded at the Fall Migration Station, and the team captures roughly a dozen individuals each year.

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