The underparts are white, with a white terminal band on the tail. The study results showed that the main reason for lifetime reproductive success in Eastern Kingbirds is due to their age longevity and ability to reproduce more often than most other birds in their lifetimes. An eye-catching bird with ashy gray and lemon-yellow plumage, the Western Kingbird is a familiar summertime sight in open habitats across western North America. This may be due to less exposure to predation from high-flying birds which provides good protection. Bird Bite: Extremely aggressive, kingbirds live up to their name. Eastern Kingbirds are monogamous and because of this, brood-parasitism is generally uncommon but quasi-parasitism is more common. This large flycatcher sallies out to capture flying insects from conspicuous perches on trees or utility lines, flashing a black tail with white edges. On the wintering grounds they eat primarily berries. It is among the earliest of migrants, bringing hope that spring is at hand. 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.

During spring migration, the kingbird follows the Mexican east coast northward back to America for mating season. Western Kingbirds eat grasshoppers. It … “Density-Dependent Age at First Reproduction in the Eastern Kingbird). “Genetic Evidence for Multiple Percentage in Eastern Kingbirds.” Behavioral Ecology and          Social Biology, Mar. 149–155. (Audobon Field Guide and Sibley Field Guide). Among a few sets of variables measured were wing span, body size, arrival times, and breeding tendencies. Eastern Kingbirds eat many wasps and bees. Kingbird Profile. 26, no. Eastern Kingbirds, like many other flycatchers are insectivores meaning they eat insects. An Eastern Kingbird is a fun bird to see while bird watching. This was probably due to certain birds having grown up in environments where crows were not common. Eastern Kingbirds eat a variety of insects, aquatic animals, rodents and small amphibians such as frogs. The population has declined in recent decades. The obvious physical advantages and other traits in the most dominant kingbirds allowed them to push through such tough conditions much better than the more average birds (Cooper, N.W. Eastern Kingbirds forage primarily by flycatching from an exposed perch. 3, Mar. Gray KingbirdThe Gray Kingbird has a gray head with black mask, larger bill. MONGO. Grey Kingbirds mostly feed on insects, such as bees, wasps, beetles and dragonflies.

Visit the Bent Life History for extensive additional information on the Eastern Kingbird. This “aggressive advantage” is a leading factor as to why Eastern Kingbirds are so abundant and dominant in a wide range of habitats. 5, May 2001, pp. The experiment helped to prove that parents are more caring and nurturing of their young and seem to care less as the young mature (Siderius, Joanne). They have long pointed wings and large broad bills. Results showed that the evolutionary response to a parasitic nest-threat wasn’t discriminatory towards any one type of invading species, but rather a response to the recognition of the parasitism of the nest in general. 1990, vol. In open country of the west, the Western Kingbird is often seen perched on roadside fences and wires, flying out to snap up insects -- or to harass ravens, hawks, or other large birds that stray too close to the kingbird's nest. Eastern PhoebeThe Eastern Phoebe is grayer, lacks the white tip to the tail. Eastern Kingbirds are very vocal and aggressive when it comes to nest defense. Wikimedia Commons. Kingbirds tend to avoid nesting near heavily forested areas as it provides less open space for hunting and mating. As the summer progresses, they eat more and more fruit. Young Eastern Phoebes have yellow wash on underparts as shonw on the image below. Eastern Kingbird. The kingbird exhibited an unorthodox pattern of population growth and eating habits that were unaffected by the fact that the lakes became more acidic. They attack predators like hawks, crows, blue jays and squirrels, sometimes knocking them out of their nests. Because they are so widespread, it would be very hard for them to significantly decline in overall population. 138, no. Nowadays, people have planted thousands (if not millions) of trees around their houses, in parks, and around cemeteries. Best of all, its gentle tail-wagging habit and soft fee-bee song make the Phoebe easy to identify, unlike many flycatchers. This brave and aggressive bird is often seen chasing larger birds of all species from its territory. Dewey, Tanya. 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). They are also less common in rural and urban populated areas. Clutch size, overall egg mass, and nest success did not vary across different locations and environments. Kingbirds who start their dawn songs earlier have a better overall morphology than later arriving kingbirds, and the early arriving singing males were more likely to mate with the earlier arriving singing females. Wiley, doi: 10.1111/j.1600-0706.2008.16997. During the buffalo prairie days, far fewer kingbirds lived on the Southern Llano Estacado. 2, 1995, pp. Depending on the season and availability, small fruits and berries make up as much as one fifth of their daily diet. Wikimedia Commons. This means that they are listed under the category of least concern by environmental analysts (BirdLife International). 3, March 1990, pp. So, it is more likely for kingbird nests to be parasitized by a member of its own of species rather than another. This delayed breeding that was observed is due to the aggressive nature of the birds, which results in the birds taking a longer time to find nesting space as well as a partner with which to reproduce. It found that the Kingbird will typically dispose of any added cowbird eggs within twenty-four hours. 143-152. Sealy, Spencer.

The Eastern Kingbird is an aerial-hawking insectivore or “flycatcher” that is quite abundant across the Northeastern United States. The birds in the rural areas lose more habitat space in those areas (Habitat-Specific Demography of a Long Distance, Neotropical Migrant Bird, The Eastern Kingbird). Eastern kingbirds evidently eat a lot of bees. 413-419. Attracting Bluebirds to watch their nesting and feeding habits can be done by placing birdhouses correctly, and, monitoring those birdhouses to prevent other species from using them.. By providing the right types of food and cover for them to raise their young, you'll make your backyard more inviting and have a greater chance at attracting these beautiful birds. “Habitat-Specific Demography of a Long-Distance, Neotropical Migrant Bird, The Eastern Kingbird.”       Ecology: A Publication of the Ecological Society of America, vol.

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. This has allowed them to become slightly dominant and more aggressive than the male. One song is its “dawn song,” and the other is its mating call. 2, 1997, pp. The birds gravitate toward small bodies of water, orchards, and grassy fields due to the open space and insects. The Sibley Field Guide to Birds in Eastern North America. Eastern Kingbirds are very vocal and aggressive when it comes to nest defense. Photographer Gregg Thompson watched Eastern Kingbirds feeding their chicks and shared photos of a “...sequence both amusing and interesting at the same time. They also eat small lizards. Due to the fact that it is difficult to introduce breeding alternations for reproductive strategies in monogamous avian organisms, it is difficult to measure the frequency of quasi-parasitism and brood parasitism in the species. Murphy, Michael. With dark gray upperparts and a neat white tip to the tail, the Eastern Kingbird looks like it’s wearing a business suit. Public Domain. 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. They dart out from perches to capture insects in their air. Incubation and fledging:The young hatch at about 14-17 days and fledge at about 3-4 weeks. 3. There it is numerous in summer, mainly along the coasts, less common toward the north. Eastern kingbirds eat insects during the breeding season and both insects and fruit outside of the breeding season. 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.

Vuilleumier, Francois. “Dawn Song of the Eastern Kingbird: An Honest Signal of Male Quality?” Animal Behaviour, vol. Also, when the birds’ nest canopy cover is generally lower and smaller in size, the nest success is higher. It is native to the nations of North America as well as Central America and much of South America and prefers forest, shrubland, and wetlands ecosystems, though it has been known to reside in rural and urban areas. —.

Eastern Kingbirds inhabit farms, roadsides, and woodland edges. Breeding/Nesting: To attract a mate, male Kingbirds display their acrobatic prowess. Hawks and crows are attacked regularly. The Eastern Kingbird can survive in stressful environments. 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. A flock of these Japanese beetle predators in your backyard can help to keep your plants free from attack by bugs but beware; chickens also adore veggies. —. These same birds also proved to be more than likely to mate with each other and at a faster rate than the other birds. In Pennsylvania, they are most abundant in the northeast and in the northwestern glaciated-regions. 2009, pp. 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. Beezhive.Wikimedia Commons. Eastern Kingbirds eat flying insects, as well as some fruits and berries. Eastern Kingbirds eat many wasps and bees. A study was performed to test different populations of Eastern Kingbirds on their response to nest predation in one controlled environment and whether or not they protected their young. 3, Jul. This is due to an abundance of open wetland habitats and resources (The Birds of Pennsylvania). Juveniles are similar, but with buffy or rusty edgings to the wing coverts. Complete Birds of North America, National Geographic Society, 2006. 3 Jul. A recent study found that Eastern Kingbirds are more likely to use the most available nest resource in their surrounding habitat. 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. Perched on a plant. The Eastern Kingbird has an attack or defense strategy that is rather brutal. Kingbirds nest in open habitats, especially trees such as hawthorns, apples, elms, mulberry, Osage-oranges, and Norway spruces. “Guide to Boreal Birds: Eastern Kingbird.” Boreal Songbird Initiative, 2015,   www.borealbirds.org/bird/eastern-kingbird.

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. A high concentration of this tree is found in central Brazil, and the Eastern Kingbird migrates in large numbers to the center of the tropical South American Country. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification. (Sealy, Spencer).
