Species: Song Sparrow
Most recent capture date: 9/29/2022
Earliest capture date: 09/16/2018
Age: four years old
Sex: male
Notes: Based on this bird’s capture history – all the times we have caught him – it looks like he spent his first winter (’18-’19) here, then spent the breeding season elsewhere, then came back again for the winter (’19-’20) and stayed, breeding at CCFS in 2020 and 2021, then disappeared again for breeding season 2022 and returned for the winter. This might just mean that we don’t always catch him when he’s around, or it might reflect changing strategies as he seeks (and competes with other males for) the best breeding spots.
