The Colima warbler (Leiothlypis crissalis) is a New World warbler. It is mainly found in the Sierra Madre Occidental and Oriental mountains of central Mexico, though its range just barely extends into adjacent southwestern Texas in the Chisos Mountains of Big Bend National Park.
The Colima warbler is about 4.5 to 5 inches (11 to 13 cm) long. They are mainly dark gray and brownish in coloration, with a pale underside. Their rump and the feathers below their tail are yellow. They have a white ring around their eye and a tinge of pale color on their breasts. Males have a spot of orange on the top of their heads.
In appearance, the Colima warbler is very similar to Virginia's warbler, but is larger in size, more robust, and heavier billed. Virginia's warbler has much more yellow or pale color on their breasts, which is grayer in the Colima warbler. The yellow above and below the tail is also more orange-yellow than the Colima warbler, and more greenish-yellow in Virginia's warblers.
Nesting is done on the ground. Forming a loose cup-shaped nest of grass, leaves, and moss the Colima warbler hides its nest among the mountain rocks. It usually lays four eggs, which are white... Wikipedia →

Rare
Under 5% of wildlife watchers report a Colima Warbler sighting in Mexico City on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 293rd most-seen of the 332 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 Colima Warbler in Mexico City on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Colima Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Colima Warbler sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Leiothlypis
The closest relatives of the Colima Warbler that you can see in Mexico City (genus Leiothlypis, Leiothlypis Warblers) are Nashville Warbler (about 30%) and Orange-crowned Warbler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Colima Warbler is recorded against all the birds logged in Mexico City (18 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.
