[cobirds] Bird Conservancy of the Rockies Chico Banding Station-May 20, 2023

A foggy morning to start the day with the sun came out @ 1000. A large selection of Swainson's Thrushes again today. From the looks of things a few birds stuck around for a day due to the weather last night. We recaptured nine birds from previous days. 

The highlight of the day was a Say's Phoebe return from 2020 banded as an adult which means it was at least three years old at banding time. The Say's Phoebe had a brood patch and she was at least six years old this year! Hoping she returns for another year or more!
