The eastern kingbird (Tyrannus tyrannus) is a large tyrant flycatcher native to the Americas. The bird is predominantly dark gray with white underbelly and pointed wings. Eastern kingbirds are conspicuous and are commonly found in open areas with scattered trees and bushes, where they perch while foraging for insects. The Eastern kingbird is migratory, with its breeding range spread across North America and its wintering range in Central and South America.
The eastern kingbird was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name of Lanius tyrannus. The present genus Tyrannus was introduced in 1799 by the French naturalist Bernard Germain de Lacépède with the eastern kingbird as the type species. The species is monotypic; no subspecies are recognised.
Adults are grey-black on the upperparts with light underparts; they have a long black tail with a white end and long, pointed wings. They have a red patch on their crown, seldom seen. They are of average size for a kingbird, at 19–23 cm (7.5–9.1 in), 33–38 cm (13–15 in) across the wings and weighing 33–55 g (1.2–1.9 oz).

With luck
About 10% of wildlife watchers report an Eastern Kingbird sighting in Boston on a given day, based on 4,087 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 283 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.
July
In that month about 30% of wildlife watchers report an Eastern Kingbird in Boston on a given day, against under 5% in September to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eastern Kingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 43

GBIF citizen-science records
It is estimated from how often the Eastern Kingbird is recorded against all the birds logged in Boston (4,087 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.
