The grey-and-white tyrannulet (Pseudelaenia leucospodia) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Ecuador and Peru. The grey-and-white tyrannulet was originally described as Elainea leucospodia. Later authors placed it in genera Phaeomyias or Myiopagis, and its original genus was later spelled "Elaenia". A 1986 publication proposed the monotypic genus Pseudelaenia for it. A genetic study published in 2009 confirmed that it belonged there and was not closely related to any of its former genera.
The grey-and-white tyrannulet is monotypic. Some authors suggest that the population in southwestern Ecuador should be treated as subspecies P. l. cinereifrons but it probably cannot be distinguished from the Peruvian population.
The grey-and-white tyrannulet is about 12.5 cm (4.9 in) long and weighs 10 to 11 g (0.35 to 0.39 oz). The sexes have the same plumage. Adults have a pale grayish brown crown with a shaggy crest whose white center is exposed when erect. They have a white supercilium and a black line through the eye on an otherwise grayish white face. Their upperparts are pale grayish brown and... Wikipedia →

With luck
About 10% of wildlife watchers report a Gray-and-white Tyrannulet sighting in Machalilla National Park on a given day, based on 55 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 94th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Gray-and-white Tyrannulet in Machalilla National Park on a given day, against under 5% in April, July and December, the lowest months. That is one of Machalilla National Park's driest months, with about 15 mm of rain against 140 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Gray-and-white Tyrannulet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Gray-and-white Tyrannulet sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Gray-and-white Tyrannulet is recorded against all the birds logged in Machalilla National Park (55 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.
