[cobirds] Bird Conservancy of the Rockies Chico Banding Station-May 8, 2023

An all around nice day to be outside and birds were singing. A Northern Waterthrush entertained us while checking the nets but did not venture into any of the nets. Four new species for the season were captured including Black-headed Grosbeak, Green-tailed Towhee, Lark Sparrow, and Least Flycatcher. Both Wilson's Warblers we captured this day were female. It seemed a bit early for the females to arrive but here they were females.

A Highlight from last Friday's banding was a Returning Bullock's Oriole banded as a Second-year bird in 2017 so it is SEVEN years old!! What a traveller!
