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.

Rare
Under 5% of wildlife watchers report a Black Phoebe sighting in Irazú Volcano National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 92nd most-seen of the 121 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.
May, August–September and November
In those months about 10% of wildlife watchers report a Black Phoebe in Irazú Volcano National Park on a given day, against under 5% in June–July, October and December–April, the lowest months.
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.
38th of 45
Of the 45 parks where we can rate Black Phoebe sightings, Irazú Volcano National Park ranks 38th at under 5%. 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.
Same family: Tyrannidae
The closest relatives of the Black Phoebe that you can see in Irazú Volcano National Park (family Tyrannidae, Tyrant Flycatchers) are Mountain Elaenia (about 50%), Black-capped Flycatcher (about 50%) and Tropical Kingbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Phoebe is recorded against all the birds logged in Irazú Volcano National Park (19 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.
