American Tree Sparrows and fall colors

Thursday, September 5

The fall colors of golden yellow are peaking in Fairbanks, Alaska. We've been lucky to enjoy the changing colors in relative comfort; we've had a relatively warm week with temperatures well above freezing. 

Captures have remained low, but have been punctuated by fun surprises. We were excited to catch a small flock of American Tree Sparrows this morning. They're easily identified by: a dark spot on their chest, bi-colored bill (dark upper mandible, yellow lower mandible), two crisp white wing bars, a chestnut crown, and a dark eye-line.
