MacGillivray's warbler (Geothlypis tolmiei) is a species of bird in the family Parulidae, the New World warblers. It is found from southeastern Alaska and western Canada to Panama. MacGillivray's warbler was formally described by John Townsend in 1839 with the binomial Sylvia Tolmiei [sic] and the English name "Tolmie's Warbler". He drew on paintings in Audubon's Birds of America, in which Audubon had confused it with what was later named the mourning warbler (Geothlypis philadelphia). Townsend's names honor his friend William Fraser Tolmie. MaGillivray's and the mourning warblers are sister species and hybridize extensively. Audubon gave the species its current English name to honor William MacGillivray.
MacGillivray's warbler was long assigned to the genus Oporornis. The American Ornithological Society moved it to its present genus Geothlypis in 2011. The IOC made the change in 2012, BirdLife International's Handbook of the Birds of the World (HBW) in 2016, and the Clements taxonomy by 2018.
However, the further taxonomy of MacGillivray's warbler is unsettled. Wikipedia →

Rare
Under 5% of wildlife watchers report a MacGillivray's Warbler sighting in Austin on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 241st most-seen of the 277 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a MacGillivray's Warbler in Austin on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most MacGillivray's Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
26th of 28
Of the 28 cities where we can rate MacGillivray's Warbler sightings, Austin ranks 26th at under 5%. The best odds are in San Luis Potosí (México, about 10%), Mexico City (México, about 10%) and Guadalajara (México, about 10%).
GBIF citizen-science records
It is estimated from how often the MacGillivray's Warbler is recorded against all the birds logged in Austin (26 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
