The Mexican chickadee (Poecile sclateri) is a small passerine songbird in the family Paridae, the tits and chickadees. It is found in Mexico and the U. S. states of Arizona and New Mexico. The Mexican chickadee was originally described in 1857 as Parus meridionalis by Philip Sclater. However, that species name had already been applied to another species (the marsh tit, now Poecile palustris), by Wilhelm Lilljeborg in 1852, invalidating Sclater's name under the principle of priority. Otto Kleinschmidt noted this, and renamed it Parus sclateri in 1897, honoring the original discoverer. It remained included in the genus Parus for much of the twentieth century. Following a 1996 publication, in 1998 the American Ornithologists' Union reassigned it to Poecile, a genus that had been erected in 1829 and had long been treated as a subgenus of Parus. A 2005 paper used mtDNA cytochrome b sequence data and morphology to agree with that change and suggest it should be universally adopted. BirdLife International's Handbook of the Birds of the World did so in 2016 and the IOC and the Clements taxonomy followed suit by 2018.

Rare
Under 5% of wildlife watchers report a Mexican Chickadee sighting in Cumbres de Monterrey National Park on a given day, based on 75 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th most-seen of the 275 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.
July–August and October–November
In those months about 10% of wildlife watchers report a Mexican Chickadee in Cumbres de Monterrey National Park on a given day, against under 5% in September and December–June, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mexican Chickadee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Mexican Chickadee sightings, Cumbres de Monterrey National Park ranks 2nd at under 5%. The best odds are in Reserva de la Biosfera Mariposa Monarca (Mexico, about 30%).
Same family: Paridae
The closest relatives of the Mexican Chickadee that you can see in Cumbres de Monterrey National Park (family Paridae, Tits, Chickadees, and Titmice) are Black-crested Titmouse (about 70%) and Bridled Titmouse (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mexican Chickadee is recorded against all the birds logged in Cumbres de Monterrey National Park (75 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.
