The Eastern Kingbird is classified as a songbird, but it is in its own songbird subgroup that innately know their calls at birth (in contrast to most songbirds that learn their calls during growth and development). 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. Eastern kingbirds eat insects during the breeding season and both insects and fruit outside of the breeding season. Vuilleumier, Francois. Also, when the birds’ nest canopy cover is generally lower and smaller in size, the nest success is higher. Springer Link, doi: 10.1007/BF00172081. Studies have revealed the kingbirds with a mid-sized wingspan to be more productive than ones with a bigger or smaller wingspan, but things such as clutch size and tarsus length had no contributing factor to the lifetime reproductive success of the birds. These birds remove cowbird eggs from their nests. 2007, pp. One experiment attempted to measure the interactions of Cowbirds with the Eastern Kingbirds. It often perches on treetops or fences flying to catch insects mid-air. 21 Jun. The typical song is a rapid series of notes such as "kidik kidik kidik kidik." With dark gray upperparts and a neat white tip to the tail, the Eastern Kingbird looks like it’s wearing a business suit. There was a clear genetic and behavioral advantage correlation between female and male kingbirds. Similar Species. This aggressive nature is due to the fact that it relies heavily on insects, other prey, and fruits (during wintering seasons) for retaining a hydration level necessary for survival (All About Birds). 143-152.

The Eastern Kingbird is highly aggressive toward nest predators and larger birds. McKitrick, M.C. Eastern Kingbird is a host of the Brown-headed Cowbird, but Kingbird recognizes Cowbird’s eggs and destroys them, breaking the membrane, causing the egg to dry and die. Both male and female participate in nest defense, but females may stay on well-hidden nests longer than females with open nests, who may leave nests earlier to chase away predators. During the fall and winter migration seasons, the birds become more social and switch their diet from insects and small rodents to tropical berries and nuts. 9 Jul. As the summer progresses, they eat more and more fruit. This means that they are listed under the category of least concern by environmental analysts (BirdLife International). Ultimately, it is much more effective to take safety precautions as opposed to fighting for safety, regardless of how fierce the Eastern Kingbird can sometimes be. The study also showed a pattern of non-territorial birds having to migrate in order to reproduce (Cooper, N.W. Males display their orange crowned plumage as they fly in a zig zag motion trying to attract potential mates. During the breeding season, Eastern Kingbirds are highly territorial and mostly eat flying insects. They prefer semi-open or open areas. Lacks the white tip of the tail.

Because they are so widespread, it would be very hard for them to significantly decline in overall population. 2008. Although the study helped to show how the kingbirds often respond to parasitism, it is difficult to currently detect the rate of nest parasitism in the species. The population has declined in recent decades. 3 Jul.

The tendency for a kingbird to re-nest in the same area as before is dependent on predatory factors from the previous nesting area. Before you care for the bird you will need to know what kind of bird it is and what it needs to survive. It isn’t only food resources that are critical for survival, though, it is also the resources for nest success. Smaller-billed than most other North American kingbirds, they probably choose smaller prey. Its light weight and broad wingspan relative to its small body allow it to be agile while also being aggressive (especially during their May-August mating season). “Density-Dependent Age at First Reproduction in the Eastern Kingbird.” Okios, vol.

It may also be found in Canada and in the South American tropics during the winter season (The Birds of North America). It was concluded that this is mostly due to an increased rate of humans moving into rural areas and new buildings being constructed. 2007. One experiment was conducted to show which characteristics of the bird contributed to migratory success. These birds wait on an exposed perch and then catch insects in flight. The voice is a burst of chattering, high, sharp kips, kitters, and tzeees.Like other flycatchers, kingbirds typically flit gracefully from an exposed perch to snap up flying insects and then immediately return to the same perch.

Of the two different types of nest “variables” being measured in the experiment, (one being a nest full of a mother’s unhatched eggs and the other being full of a mother’s young), there were no distinct results showing if an adult kingbird was more likely to defend their unhatched young as opposed to hatched young. Rain and colder environments are bad for food because there are few insects to eat in harsh, cold, and/or wet conditions during the migrating time for the kingbirds. The Eastern Kingbird’s nest is a cup of twigs, grasses, and weeds placed on a tree branch, often over water.
