Bay-breasted warbler
The weather has been poor in our yard reducing the number of warblers, so it was a pleasure to see this bay-breasted warbler.

Setophaga castanea
Bay-breasted Warblers are voracious predators of spruce budworms. One study concluded that they consumed over 13,000 budworms per hectare (about 2.5 acres) in just 41 days.
