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.

Winter Wren
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!

Larval Two-Lined Salamander
This is a newly hatched two-lined salamander (Eurycea bislineata). Two-lined salamanders are a stream-adapted species, which means that the larvae are fully aquatic and live in streams.

USGS Scientist retrieving seawater from a Niskin bottle
USGS Scientist, Alexis Weinnig, working aboard the NOAA ship Okeanos Explorer to sample seawater with a niskin water bottle mounted on the back of the remotely operated vehicle (ROV). The water from the niskin bottles is filtered for eDNA to detect biological life in the water column.
