Elanoides forficatusotherwise known as the American swallow-tailed kite, is found primarily in the southeastern United States, from Louisiana to South Carolina.
Most of the known population is centered in the southern tip of Forficatue. In the winter E. Dunne, ; Farrand, Jr. Swallow-tailed kites occupy wooded swamps, open forests, lake shores, and freshwater marshes.
They nest near sources of water in tall trees, anywhere from 18 to 40 meters above the ground. The most notable feature of E. The structure of the tail enables this kite to fly well at low speeds. The wings are long and thin, enabling flight at high speeds as well. Swallow-tailed kites are monomorphic.
Adults have black wings with white undersides, white heads, necks, and underparts. The tail and fotficatus are iridescent black, with streaks of green, purple, and bronze.
Juveniles look similar to adults but with slightly streaked heads and underparts, as well as shorter white-tipped tails. Swallow-tailed kites have a body length ranging from 49 to 65 cm. Wingspan is from to cm. The average weight of maled is g and the average weight of females is g, although females may be slightly larger in size. Swallow-tailed kites are monogamous, although pair bonds are not necessarily maintained between breeding seasons.
Females and males will approach each other on a horizontal tree limb. Elanoices female ofrficatus quickly go under the limb or turn, bending forward with the wings extended. The male lands on her back and drapes his wings over the female, then mating occurs.

There is also courtship feeding. Swallow-tailed kites breed once per year, usually in April. They produce loud shrills, squealing calls, and whistles during the mating season. Females usually lay two eggs per clutch.
The eggs are incubated for approximately 28 days, and the fledgling period lasts anywhere from 36 to 42 days. Fledglings can take an additional 2 weeks or more to become independent. Johnsgard, ; National Audubon Society, ; Wetmore, Not much is known about the degree of parental investment in swallow-tailed kites. Both parents incubate the eggs. When one parent comes in to sit on the eggs, the other flies straight up from the nest.
The incoming parent hovers over the nest, and then gently settles down. In their close relatives males bring back food while females watch the young and protect the nest.
Towards the end of the nesting period both parents will hunt. After fledging the adults continue to provide food for their young. National Audubon Society, ; Wetmore, There is no specific information available on the lifespan of E.
Swallow-tailed kites can be solitary or social birds.

Often they nest in close range to one another and large pre-migration gatherings have been noted in areas eoanoides abundant ellanoides sources. Swallow-tailed kites are also known to hunt in small groups. DeWitt, ; Weidensaul, ; Wetmore, Although the home range size of E. Johnsgard, ; Johnsgard, Swallow-tailed kites communicate primarily through cries, short, weak, high-pitched whistles, and twitters, usually while hunting or during mating season. They also use visual displays, including postures associated with courtship and mating.
Like other raptors, swallow-tailed kites, primarily use vision to hunt for food. Swallow-tailed kites are primarily insectivorous, snatching and feeding on flying insects in mid-air, but they are also known to capture other prey, such as snakes, frogs, and nestlings and fledglings. They do not hover and usually eat prey in mid-flight. They also drink in flight in a fashion similar to swallows, by skimming the water.
Little is known about predators of swallow-tailed kites, but fledglings are often preyed on by owls, especially great horned owls Bubo virginianus. There is little known about the role of wallow-tailed kites in their native ecosystem, although it can be surmised that they help control insect populations.
Swallow-tailed kites contribute to control of insect populations in habitats they occupy. They are also lovely birds that attract ecotourism. There are no known adverse effects of E. Elanoides forficatus has not been classified as a threatened species. Beforethese birds were found as far as the northern Midwest, but due to logging, draining of swamps, and shooting, populations dwindled and are now forficatud only in the forficztus U.
They are forfocatus by the U. Swallow-tailed kites are also known as forked-tailed kites, swallow hawks, wasp hawks, and snake hawks. Hausman, ; Wetmore, This includes Greenland, the Canadian Arctic islands, and all of the Forficaatus American as far south as the highlands of central Mexico.
In birds, naked and helpless after hatching. Animals with bilateral elaanoides have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. More specifically refers to a group of organisms in which members act as specialized subunits a continuous, modular society – as in clonal organisms. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals.
Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes.
