MacGillivray's WarblerGeothlypis tolmiei
- ORDER: Passeriformes
- FAMILY: Parulidae
A furtive bird of forest edges and thickets, MacGillivray's Warbler breeds across much of the Pacific Northwest and the Rocky Mountains. In appearance, voice, habits, and winter range, it resembles its close relative, the Mourning Warbler, but the breeding ranges of the two species do not overlap.More ID Info

- Cool Facts
- MacGillivray's Warbler and Mourning Warbler are now considered distinct species, but in the recent past, they have been considered to be the same species on the basis of similar plumages and possible cases of hybridization where their ranges overlap. Size disparity (MacGillivray's is smaller), consistent differences in morphology and song, and physical separation of breeding ranges supports the recognition of separate species.
- MacGillivray's Warbler nests from near sea level to as high as 3,000 meters (9842 ft) in elevation.
- MacGillivray's Warbler was named by John James Audubon for his friend and editor, 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 oldest recorded MacGillivray's Warbler was a male, and at least 4 years, 1 month old when it was recaptured and rereleased during banding operations in Oregon.
