Formerly known as Sparrow Hawk, American kestrel is the smallest, most numerous, and most North American Falcon in the category of both male and female. This article will give an overview of American kestrel females.
Out of the 4 rare species found in the world, it is the only one found in the Western Hemisphere, where about 17 species are recognized in Alaska and Canada’s Tierra del Fuego.
This colorful falcon is sexually ambiguous: the male has a rufous tail with blue-gray wings and a single broad subterminal black band, while the female is bored with black bars across the wings and tail lengths.
The American kestrel female has different variations. The species also shows sex-sized dimorphism, about 10% heavier than males.
Our youngest Falcon, an American kestrel female is also the most known and widely known in North America. In the open country, it is usually seen gathering on the side of a road or wandering under a field on fast-beating wings, waiting to jump on the grassland.
American kestrel female nests in cavities in trees; Places that have a few big dead snags to supply the nest site can rely on nest boxes kept for them by conservationists.
Habitat
Open country, farmland, city, wood edge. Prevents any kind of open or semi-open conditions from clearing the forest to farmland to the desert, wherever it finds suitable prey and some raised perch.
During the breeding season, habitats can be limited to sites that provide suitable nesting sites. In winter, wives are seen in more open housing than men.
Feeding behavior
The hunters mostly hunt from the high perch, then fall down to catch the prey. Sometimes, especially when a good perch is not available, wander the fields to look for prey.
The fly can chase and catch insects, birds or bats. Separate American kestrel female often specialize in a particular type of prey.
Egg
4-6, rarely 2-7. White to pale brown, usually stained with brown and gray. Incubation is usually between 28-30 days for both parents.
Youth: American kestrel female is often with young man, while the male brings food; 1-2 weeks later, the female also preyed. About 28-31 days old on the first flight.
The parents feed the baby for up to 12 days after the escape; Later, these teens can team up with young people from another home.
Young
The American kestrel female is often with the young for the first time, while the men bring food; 1-2 weeks later, the female also preyed. About 28-31 days old on the first flight.
The parents feed the baby for up to 12 days after the escape; Later, these teens can team up with young people from another home.
Diet
Most large insects; Also some small mammals, birds, reptiles. Grasshoppers are the preferred prey, but many more insects, including beetles, dragonflies, insects, predators, etc. are taken by American kestrel female.
It also feeds on mammals (including wolves, rats, and sometimes bats), small birds (sometimes in the form of coils), ticks, frogs, insects, spiders, crayfish, and other items.
Of birds
During the courtesy display, the American kestrel female gently flies the wings with tight, flattened wings. Men repeatedly make loud calls call and dive.
Men bring food for the girls, give it to them on the flight. The nest site is in a cave, usually in dead trees or pruned, sometimes in dirt or draft or in old magpies nests.
In the southwest, often in the pit of the giant cactus. It also uses artificial nest boxes. Sites are usually 10-30 ‘up but can be at any height.
American kestrel female lives in open spaces where they mostly hunt from perch, often with utility cables alongside road berms, but also by traveling, especially when there is a lack of suitable parks.
A rotating bird faces the wind, the head is clearly fixed, but the wings are periodically turned upside down and backward, and the tail regularly adjusts to each eddy in the air.
It eats arthropods and small vertebrates, usually capturing the ground, although some individuals become skilled at flying insects and small birds.
American kestrel female is attracted to human-modified habitats such as pastures and parkland and is often found near human activity zones, including several advanced urban areas.
This Falcon uses a secondary cavity nester, woodcut-excavated or natural cavity in large trees, grooves in stone and designs in buildings and other structures.
The availability of suitable cavities limits its population in many parts of the breeding range. Species are simply using artificial nest boxes and there is a growing public interest in participating in nest-box programs.
Many aspects of the life history of this species, including pasture and nesting behavior, have been well studied.
Notable among these works is an illustration of the behavior and ecology of the reproduction and reproduction of American kestrel females in natural cavities in northern California.
Other researchers maintain hundreds of nest boxes that support the study population.
These investigations include reproductive strategies (for example, parental investment, adaptive shifts in the sex ratio of the child, successive behaviors and provide information on geographical variation in the characteristics of plumage).
These long-term studies of identified individuals are especially valuable because they will likely yield important information on population image and lifetime reproductive success (this is a direct measure of fitness).
American Kestrel is a great laboratory animal as well. It easily breeds in captivity and serves as a primary model of organochlorine pesticide bioactivation in prey birds.
It was the first Hajj produced by artificial insemination and the first from frozen semen.
