INTERESTING FACTS

  • Black-throated Blue Warblers are ideal songbirds to study because their nests in the shrub layer are relatively easy to find and monitor, and their plumage allows one to readily determine the sex, and with practice, even the age of individuals.
  • The sexes of the Black-throated Blue Warbler look so different that they were originally described as two different species.
  • They are among most trusting and tame of their family. If an observer moves very deliberately, a bird may be approached to within a few feet.
  • A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
