Due to freezing early morning temperatures, we waited a couple hours before opening any nets at the gulch. At 9:30 AM, we opened half of the nets, and the first bird caught and banded was an American Tree Sparrow, a sign of approaching winter.
Banding American Tree Sparrows is a sign that
the fall banding season will soon be over.
Brown Creepers are very exciting to see up close! We caught and banded two today.
Another nice treat was this Mountain Chickadee.
