The black phoebe (Sayornis nigricans) is a passerine bird in the tyrant-flycatcher family. It breeds from southwest Oregon and California south through Central and South America.

Six subspecies are commonly recognized although two are occasionally combined as a separate species, the white-winged phoebe.
The black phoebe has predominantly black plumage, with a white belly and undertail coverts. The sexes are identical in color, and juveniles have brown feather tips and brown wing-bars. Its song is a repeated tee-hee, tee ho. It lives in a variety of habitats but is always near water. It is mainly insectivorous and waits on a perch before sallying out and catching its prey in the air. It makes an open cup nest which is placed under a cliff or a bridge and cemented in its place with mud.
The black phoebe is a medium-sized flycatcher, being 16 cm (6.3 in) in length and weighing 15 to 22 g (0.5 to 0.8 oz). It has predominantly black plumage, with white on its belly and undertail coverts. The white forms an inverted... Wikipedia →

Possible
About 30% of wildlife watchers report a Black Phoebe sighting in Yosemite National Park on a given day, based on 1,060 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 169 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and December–January
In those months about 40% of wildlife watchers report a Black Phoebe in Yosemite National Park on a given day, against about 20% in May–June and August–September, the lowest months. Those are among Yosemite National Park's wettest months, with about 160 mm of rain a month against 25 mm in September.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black Phoebe sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 45
Of the 45 parks where we can rate Black Phoebe sightings, Yosemite National Park ranks 11th at about 30%. The best odds are in Channel Islands National Park (United States, about 70%), Amboró National Park (Bolivia, about 60%) and Death Valley National Park (United States, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black Phoebe is recorded against all the birds logged in Yosemite National Park (1,060 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.
