Fun fact about this bird (from Cornell University All About Birds) ~

“In contrast to the more stable populations of other warblers, Bay-breasted Warbler numbers go up and down depending on outbreaks of the spruce budworm. The birds are abundant during infestations, but decline or even disappear from some areas a few years later.”

Apparently the Bay-breasted warbler is a very picky eater.
