Horse colour terminology warblers

Spring male Chestnut-sided warbler

Like the Bay-breasted, the Chestnut-sided's name refers to horse colour terminology.  I'm glad there isn't a roan warbler or a grey warbler, but can mostly handle these two.  And when they were named it wouldn't have been the least bit obscure, and at least the bird really is chestnut-sided.

Hundred percent crop, and the bokeh-ghosts of various other sticks give some indication why I'm pleased it's in focus at all.  Also from Trinity Bellwoods Park.
