Rare
Under 5% of wildlife watchers report a Black-billed Shrike-Tyrant sighting in Quito on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 167 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Black-billed Shrike-Tyrant in Quito on a given day, against under 5% in July to May, the lowest months. That is one of Quito's driest months, with about 60 mm of rain against 180 mm in April.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black-billed Shrike-Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Black-billed Shrike-Tyrant sightings, Quito ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Santiago (Chile, under 5%).
Same family: Tyrannidae
The closest relatives of the Black-billed Shrike-Tyrant that you can see in Quito (family Tyrannidae, Tyrant Flycatchers) are Southern Beardless-Tyrannulet (about 40%), Vermilion Flycatcher (about 40%) and Tufted Tit-Tyrant (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-billed Shrike-Tyrant is recorded against all the birds logged in Quito (9 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.
