Common and conspicuous in summer, it is often seen perched jauntily on a treetop or fence wire, or sallying out with shallow fluttering wingbeats to catch an insect in mid-air. Monthly heatmap of the presences (GBIF 2019) with kernel density estimation of the Eastern Kingbird (Tyrannus tyrannus) through the American continent. They swallow small insects without bothering to land. They overwinter in South America, primarily western Amazonia, where they forage in flocks in the forest canopy at the edges of rivers and lakes.Back to top, Eastern Kingbirds catch insects in midair during spring migration and on the breeding range, including bees, wasps, ants, beetles, crickets, grasshoppers, locusts, bugs, and flies. It has an exterior of small twigs, coarse roots, dry weed stems, strips of bark, and sometimes bits of trash such as cigarette butts, plastic, and twine. Ornithol.

We modeled monthly density heatmaps and evaluated the annual migratory movements of the bird in the southern hemisphere using the records available in the Global Biodiversity Information Facility repository.

The Eastern Kingbird usually breeds in fields with scattered shrubs and trees, in orchards, and along forest edges. It could be explained by an increase in the use of citizen science repositories, or it could be a species’ reaction to climate change (Schulz et al. Eastern Kingbirds also attack large nest predators like crows and Blue Jays; such aggression has been shown to increase their breeding success.Back to top, Eastern Kingbird is numerous and widespread but populations decreased by 47% between 1966 and 2015, according to the North American Breeding Bird Survey. 1a, blue arrows) usually reaching the Amazonia of Peru, Bolivia, and some areas of southwestern Brazil (Murphy and Pyle 2020; Fink et al. Pale and smooth with a striking ring of irregular reddish spots. Rev Bras Ornitol 22:260–264. Partners in Flight estimates a global breeding population of 27 million, with 84% breeding in the U.S. and 16% in Canada. The most widespread of our kingbird species, it breeds throughout North America, with the exception of northern Canada and the southwestern United States. Eastern Kingbirds prefer large insects, which they take back to the perch, beat into submission, and swallow whole. It is drawn to water, often nesting densely in trees that overhang rivers or lakes.

Thus, the trans-Andean status of this species remains unconfirmed despite being likely because of its three confirmed records (with photographs) in highlands: one above 3000 m in Ecuador (Murphy and Pyle 2020), and two in the highland wetlands in the region of Cusco, in the south of Peru, at 3100 m (Huasao wetland, 13° 34′ 24.8″ S 71° 48′ 32.4″ W; Huarcapay lagoon, 13° 37′ 04.9″ S 71° 43′ 49.5″ W; Sullivan et al. On their spring migration most birds follow the east coast of Mexico northward, then fan out across the eastern United States. It is the most widespread black-and-white species of the genus Tyrannus, and it differs from others because of a series of specific morphological features.

Hollow dots show the species’ southernmost localities each year, black dots are the records in arid ecosystems of western South America. Males and sometimes females are very aggressive in territorial disputes, often resorting to aerial fights in which they lock feet together, pull out each other’s feathers, and sometimes fall to the ground.
