INTERESTING FACTS

  • The Bay-breasted Warbler is closely related to the Blackpoll Warbler, and hybrids between the two species are known. They are also known to hybridize with Yellow-rumped and Blackburnian warblers.
  • Eighty-two percent of the global population of Bay-breasted Warbler nests in the boreal forest of North America.
  • In contrast to the more stable populations of other warblers, their numbers go up and down depending on outbreaks of the spruce budworm. They are abundant during infestations, but decline or even disappear from some areas a few years later.
  • A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
