A handsome greenish-yellow, black, and white warbler with a chestnut streak on its sides is sitting on a branch singing his heart out. It’s a Chestnut-sided Warbler. Males sing an accented-ending song, with louder concluding notes. Many birders find it useful to remember the song by linking it with the mnemonic "see-see-see-Miss-BeeCHER." Nearly all singing is done within the male's territory, usually from elevated perches in trees. Males sing and forage intermittently, hopping from branch to branch. This photo was taken in a site along the Ausable River, which is also home to a variety of other warblers.

On my way out of Green-Wood Cemetery on Saturday before 7pm 9/20/2025 saw a little bird flitting around in the shadows. Here it is: adorable Chestnut-sided Warbler! I love them both in breeding & Fall plumage. #chestnutsidedwarbler #warblers #birds #fallmigration #birdwatching

The wildfire smoke was really bad in this area of Quebec from the fires in Manitoba and Saskatchewan, so I didn't spend too much time outdoors. But long enough to watch this Chestnut-sided Warbler forage about for insects in the trees near my deck.

Chestnut-sided Warbler
I was super thrilled to see this bird at a park at the end of my street. I often see these birds in natural areas but this is the first time I've seen one in Parkdale.

🌎 Chestnut-sided warbler (Setophaga pensylvanica) The chestnut-sided warbler is a small songbird with a yellow crown, black eye stripe, white cheeks, and in breeding plumage, distinctive chestnut flanks. Females are duller. Non-breeding adults are lime-green above with a white eye-ring and pale underparts. Chestnut-sided warblers breed in eastern North America, favoring young, regenerating forests and shrubby areas, and winter in Central America. They forage actively among low branches for insects, often holding their tail cocked. Their song is a musical "pleased, pleased, pleased to meetcha!". No subspecies are recognised.
