The olive warbler (Peucedramus taeniatus) is a small passerine bird. It is the only member of the genus Peucedramus and the family Peucedramidae. This species breeds from southern Arizona and New Mexico, USA, south through Mexico to Nicaragua. It is the only bird family endemic to North America (including Central America). It was in the past classed with the Parulidae (New World warblers), but DNA studies suggest that it split early from the other related passerines, prior to the differentiation of the entire New World warbler/American sparrow/Icterid group. It is therefore now given a family of its own.
It is an insectivorous species of coniferous forests. Though it is often said to be non-migratory, most New Mexican birds leave the state from November to late February. It lays 3–4 eggs in a tree nest. The olive warbler was originally placed in the New World warbler (family Parulidae) genus Dendroica, a group which it closely resembles, particularly in having nine primaries and similar skin. In spite of being assigned to its own genus in 1875, its affinities were a source of contention. The shape of the basihyal bone in the skull, and aspects of its behaviour led to... Wikipedia →

Rare
Under 5% of wildlife watchers report an Olive Warbler sighting in Mexico City on a given day, based on 413 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 332 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.
October and December–January
In those months about 10% of wildlife watchers report an Olive Warbler in Mexico City on a given day, against under 5% in February–September and November, the lowest months. Those are among Mexico City's driest months, with about 25 mm of rain a month against 150 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Olive 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.
2nd of 3
Of the 3 cities where we can rate Olive Warbler sightings, Mexico City ranks 2nd at under 5%. The best odds are in Toluca (México, about 10%).
Same order: Passeriformes
The closest relatives of the Olive Warbler that you can see in Mexico City (order Passeriformes, Perching Birds) are House Finch (about 80%), Bewick's Wren (about 80%) and Great-tailed Grackle (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Olive Warbler is recorded against all the birds logged in Mexico City (413 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.
