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.

Possible
About 20% of wildlife watchers report an Ash-throated Flycatcher sighting in Saguaro National Park on a given day, based on 1,842 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report an Ash-throated Flycatcher in Saguaro National Park on a given day, against under 5% in October to February, the lowest months. That is one of Saguaro National Park's driest months, with about 5 mm of rain against 55 mm in July.
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.
7th of 17
Of the 17 parks where we can rate Ash-throated Flycatcher sightings, Saguaro National Park ranks 7th at about 20%. 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.
GBIF citizen-science records
It is estimated from how often the Ash-throated Flycatcher is recorded against all the birds logged in Saguaro National Park (1,842 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.
