The American kestrel is about 30 cm (12 inches) long, white or yellowish below and reddish brown and slate gray above, with colourful markings on the head.

Is the American kestrel population declining?

Data on population numbers, from sources including the U.S. Geological Survey’s Breeding Bird Survey (BBS) and the National Audubon Society’s Christmas Bird Count, indicate that American Kestrel populations have been declining across the United States for decades.

How does the southeastern American kestrel feed?

During feeding, the Southeastern American kestrel will use a perch to locate and observe its prey, then fly in and catch the prey with its feet. The diet of the Southeastern American kestrel primarily consists of grasshoppers and lizards, but they will also eat spiders and frogs. Breeding begins in March and concludes in June.

Why do American kestrels hold starlings better than Merlins?

It is a simple fact that American kestrels hold starlings better than merlins, on average, and will gladly tackle larger quarry than will any jack (male merlin).” American kestrels do not train so easily as some larger falcons (particularly the peregrine falcon) in the art of “waiting on” to perform a diving stoop on flushed prey.

Is the Kestrel an endangered bird?

Unlike other raptors, the kestrel’s downturn is more reminiscent of the loggerhead shrike, a chunky songbird smaller than a robin whose numbers have fallen by 76 per cent since 1966. Once common here, they are now extinct in Quebec and considered endangered in the rest of Canada.

Where do kestrels live in Florida?

American Kestrels can be found year-round in the majority of Florida. The southern tip of the state also has migrants in the wintering season. Because females migrate first, they typically take up all the open habitat and leave the males to use more wooded areas. These birds are cavity dwellers, and will nest in bird boxes if they are up in time.

Why is the southeastern American kestrel endangered?

The main threat to the Southeastern American kestrel is the loss of nesting and feeding habitat. These habitats are destroyed during the development of new residential areas and farm lands, removal of trees in agriculture fields, and the alteration of fire-maintained pine habitats by suppressing fire.

Do nest boxes help American kestrels?

If you are interested in installing a nest box with the intention of helping kestrels, you’ve come to the right place! Research shows that nest boxes aren’t a golden ticket to American Kestrel conservation.

Is the American kestrel declining?

Back to top The American Kestrel is the continent’s most common and widespread falcon, but populations declined by an estimated 1.39% per year between 1966 and 2017, according to the North American Breeding Bird Survey. That annual trend corresponds to a 51% cumulative decline over the full period.

Where do American kestrels breed?

American Kestrels favor open areas with short ground vegetation and sparse trees. You’ll find them in meadows, grasslands, deserts, parks, farm fields, cities, and suburbs. The southeastern U.S. form breeds in unusual longleaf pine sandhill habitat.

How many eggs do American kestrels lay?

American kestrels usually lay between 3 and 7 eggs. The baby birds fledge in about 30 days and will leave the nest and become independent about 30 days after fledging. 10. American kestrels cache their kills

How do American kestrels nest?

A cavity nester, American Kestrels will use holes in trees, rock cavities and crevices in cliffs, artificial nest boxes, or small spaces in buildings. The number of suitable breeding cavities limits this species’ breeding density. The American Kestrel has adapted well to nest boxes.

How many kestrels are there in North America?

The American Kestrel’s North American population has been estimated at 1. 2 million pairs, with the Central and South American populations being as large. It is possible that the clearing of parts of North America for agriculture in the last two hundred years has caused the American kestrel population to increase.

Is a kestrel a Falcon?

The Kestrel (Falco tinnunculus) is also known as the European Kestrel, Eurasian Kestrel or Old World Kestrel. In Britain, where no other brown falcon occurs, it is generally just called ‘the Kestrel’. The Kestrel is one of the most common birds of prey found in Britain.

What do kestrels do during breeding season?

During the breeding season, the bird will carry large prey back to its mate or young. One study found that an American kestrel pair “foraged in ways that minimized the costs of energy acquisition in its particular situation”.

What is the difference between a Merlin and a kestrel?

Merlins are small dark falcons just slightly larger than Kestrels. They measure 10 to 12 inches long and have wingspans of 24 to 27 inches. Immature Merlins are brown above, while adults are blue-gray; both young and adult birds have heavy dark brown vertical streaks on their underparts.

Why do kestrels live in grasslands?

Grassy areas provide excellent habitat for kestrel prey species and an assortment of other grassland birds. American kestrels have been affected by compounds like DDT and other agricultural and home lawn chemicals that can cause reproductive failures. Pesticides also affect smaller birds that kestrels may prey upon.

What is the difference between a kestrel and a hawk?

Although all hawks have certain basic similarities such as keen eyesight, hooked beaks and taloned feet, a wide diversity of forms and sizes exists among them. For instance, an American Kestrel weighs only 4 ounces, while a Bald Eagle can weigh 13 pounds – 52 times as much. Hawks are efficient predators.

Where do kestrels live in the wild?

Kestrels usually occur in open country, such as grasslands and farmland, and avoid dense forests unless they have been opened up by clearing. They hunt a variety of prey, including small mammals (especially mice), small birds, lizards and insects.
