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 →

With luck
About 10% of wildlife watchers report an Olive Warbler sighting in Toluca on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 118 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report an Olive Warbler in Toluca on a given day, against under 5% in February, the lowest month. That is one of Toluca's wettest months, with about 150 mm of rain against 5 mm in December.

GBIF citizen-science records
It is estimated from how often the Olive Warbler is recorded against all the birds logged in Toluca (27 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.
