Description
The american Kestrel (Falco sparverius) is the smallest falcon in North America, but also the most common. It can also be found in South America and usually hunts from the ground rather than in the air. The female is allowed to choose their mates when on the breeding ground, so the males attract them with dances and displays.

Feeding Habits
American Kestrel's diet mainly consists of insects like grasshoppers, beetles, and cicadas; arachnids; and small vertebrates including rodents, bats, birds, and occasionally snakes, lizards, and frogs. American Kestrel demonstrates adaptability in feeding habits, maintaining high population densities due to its varied diet.
Habitat
American Kestrel flourish across temperate to tropical areas, favoring open environments like grasslands, deserts, savannas, and agricultural fields. Adaptable to human presence, they inhabit urban to suburban spaces, utilizing both natural and artificial structures for perching and nesting. Sparse vegetation and hunting opportunities are essential to their choice of habitat, with nesting cavities being pivotal during breeding.
Nest Behavior
American Kestrels have the male search and suggest nest sites. The female selects, and they lay eggs in spring, with parental care shared amongst the pair.
Nest Characteristics
American Kestrel's nests are typically in cavities like old woodpecker holes, tree hollows, rock crevices, or building nooks. They don’t use nesting materials but may form a shallow depression.

Behavior
American Kestrel engage in diurnal hunting, often perching in one location for an extended period to scan for prey or hopping between perches. They pounce to capture prey, consuming small victims on site or transporting larger ones to a perch. During the breeding season, american Kestrel exhibit specific mating behaviors, such as males performing climbing and diving displays with distinctive calls to assert territory and attract mates. Gift exchanges of food, typically from male to female, are also part of their courtship ritual. American Kestrel may congregate in small groups early in the breeding season. They are known to confront larger raptors in defense of their territory and compete aggressively with other cavity-nesting species for nesting sites.
Species Status
The American kestrel is likely the most abundant falcon in North America, although its total population is difficult to quantify, as local populations can change quickly due to resource availability. Count data from the USGS Breeding Bird Survey (BBS) indicate that the North American breeding population is experiencing long-term and gradual but sustained declines, with some regions, such as New England and coastal California, exhibiting more rapid declines.
