In North America, this species breed from South Carolina to Florida in the east, and to Texas, and Louisiana in the west. Most of its population is found in Florida and in the deep south. Their migration takes place during winter when they settle in the northern part of South America for some time. The South American native population is mostly found in northern Argentina, and eastern Peru, where they stay year round. The scattered population are found in West Indies, and Mexico.

Adaptation of Swallow tailed kite

Approximately three percent of its total population breed in North America. They migrate thousands of miles in order to find a suitable habitat along coastal wetlands. Researchers have found that some individuals cover more than 10000 miles during migration. They have a highly manoeuvrable flight and keen eyesight. They can catch insects while in flight. They take much of their food by descending low over lower growths or trees and preying upon creatures without pausing.

Reproduction and Behavior of Swallow tailed kite

Breeding takes place from March to May. They often form monogamous pairs. Nesting sites are generally in high trees in open forestland, primarily in pine, cypress or connonwood.

Reproduction and Behavior of Swallow tailed kite

Reproduction and Behavior of Swallow tailed kite

They take around four days to make a breeding nest using small sticks as a platform, lined with Spanish moss and soft lichens. Sometimes, pairs return to the same location where they bred the previous season. Mating rituals involve aerial chases by both male and female. Sometimes, the male can be seen feeding the female. Females lay 2 – 4 eggs that are creamy white in color, marked with brown patches. Both sexes take part in incubation that lasts for 28 to 30 days. In the first week, following hatching, young ones are brooded by female; while males bring food to the nest. After two to three weeks, females also go for a hunt in order to feed the young ones. The young ones can move after five weeks, and their first flight takes place in 5 to 6 weeks.

Swallow tailed kite Interesting Facts

  • Alterations in wetland hydrology and habitat degradation have shrinked its native range and have triggered a massive decline in population. Habitat degradation and deforestation in its migration routes have also caused adverse effects in breeding.

  • Florida’s Lower Suwannee National Wildlife Refuge is an important conservation area. The population have increased as of 2016. Also, in places like Georgia, habitat restoration and its management has proved to be successful.
