The ash-throated flycatcher (Myiarchus cinerascens) is a passerine bird in the tyrant flycatcher family. First described in 1851 by George Newbold Lawrence from a specimen collected in western Texas in the United States, the ash-throated flycatcher was initially given the scientific name Tyrannula cinerascens. The species was mistakenly described again in 1851 as Tyrannula mexicanus — an error that was corrected in 1859 when Philip Lutley Sclater analyzed the tyrant flycatchers known from Mexico and realized that both scientific names referred to the same species. During the same analysis, Slater moved the ash-throated flycatcher from the genus Tyrannula to its current genus, Myiarchus. In the past, the ash-throated flycatcher has sometimes been considered to be conspecific with Nutting's flycatcher, but there are morphological and vocal differences between the two. There is disagreement as to whether the two species hybridize.

Rare
Under 5% of wildlife watchers report an Ash-throated Flycatcher sighting in Yosemite National Park on a given day, based on 129 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 92nd most-seen of the 169 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report an Ash-throated Flycatcher in Yosemite National Park on a given day, against under 5% in July to April, the lowest months. Those are among Yosemite National Park's driest months, with about 40 mm of rain a month against 220 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ash-throated Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 17
Of the 17 parks where we can rate Ash-throated Flycatcher sightings, Yosemite National Park ranks 13th at under 5%. The best odds are in Cabo Pulmo National Park (Mexico, about 60%), Big Bend National Park (United States, about 50%) and Bahía de Loreto National Park (Mexico, about 30%). All parks ranked.
Same family: Tyrannidae
The closest relatives of the Ash-throated Flycatcher that you can see in Yosemite National Park (family Tyrannidae, Tyrant Flycatchers) are Western Wood-Pewee (about 40%), Black Phoebe (about 30%) and Dusky Flycatcher (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ash-throated Flycatcher is recorded against all the birds logged in Yosemite National Park (129 verified sightings from 2019 to 2026), 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.
