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 Reserva de la Biosfera Mariposa Monarca on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 49th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February–March and November
In those months about 20% of wildlife watchers report an Olive Warbler in Reserva de la Biosfera Mariposa Monarca on a given day, against about 10% in May, October and December–January, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 35 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
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.
Yes
Of the 4 parks where we can rate Olive Warbler sightings, Reserva de la Biosfera Mariposa Monarca has the highest daily chance: about 10%. Next come Celaque National Park (Honduras, about 10%) and Cumbres de Monterrey National Park (Mexico, under 5%).
Same order: Passeriformes
The closest relatives of the Olive Warbler that you can see in Reserva de la Biosfera Mariposa Monarca (order Passeriformes, Perching Birds) are Yellow-eyed Junco (about 80%), Ruby-crowned Kinglet (about 70%) and Red Warbler (about 50%), 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 Reserva de la Biosfera Mariposa Monarca (24 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.
