Bay-breasted warbler


Another spring migrant at Rondeau.


We have had a large number of bay breasted warblers this year compared to previous years.
Normally they are hard to find and stay way up in the trees.
This year some were down low and they posed for photographs.

Setophaga castanea

A large warbler of the northern spruce forests, the Bay-breasted Warbler benefits from spruce budworm outbreaks when the caterpillars provide abundant food. Spraying to control the destructive outbreaks may have reduced populations of this warbler.
