The gray thrasher (Toxostoma cinereum) is a medium-sized passerine bird belonging to the family Mimidae. It is endemic to the Baja California peninsula of Mexico. The gray thrasher is 21.4 to 25.0 cm (8.4 to 9.8 in) long. Four males weighed 58.6 to 69.8 g (2.07 to 2.46 oz) and a female 54.4 g (1.92 oz). It is gray-brown above with cinnamon tones on the rump. Its underparts are white with arrow-shaped black spots. The outer tail feathers have white tips. Its eyes are golden yellow. The subspecies are similar, with T. c. mearnsi being somewhat darker overall.
The gray thrasher is found only in Mexico's Baja California, where its range extends from approximately north latitude 31°14' to its southern tip. On the east side of the peninsula, however, it is found only as far north as approximately 28°. There is a record of this species in the Famosa Slough, San Diego County, California. T. c. mearnsi occupies approximately the northern half of the range and the nominate subspecies the southern half.

With luck
About 10% of wildlife watchers report a Gray Thrasher sighting in El Vizcaíno Biosphere Reserve on a given day, based on 116 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 237 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–March, May–August and October
In those months about 10% of wildlife watchers report a Gray Thrasher in El Vizcaíno Biosphere Reserve on a given day, against under 5% in April, September and November–December, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Gray Thrasher sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.

GBIF citizen-science records
It is estimated from how often the Gray Thrasher is recorded against all the birds logged in El Vizcaíno Biosphere Reserve (116 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.
