INTERESTING FACTS

  • MacGillivray's and Mourning Warblers are now considered distinct species, but in the past they had been thought to be the same species on the basis of similar plumages and possible cases of hybridization where their ranges overlap.
  • It was named by John James Audubon for his friend Dr. W. MacGillivray. Audubon coined this name even though John Kirk Townsend had already named the species "Tolmie's Warbler," after Dr. W. T. Tolmie. The scientific name "tolmiei" was given in his honor.
  • Size disparity, consistent differences in morphology and song, and physical separation of breeding ranges supports the recognition of separate species.
  • A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
