How does a kestrel reproduce?

Kestrel Reproduction Kestrels nest on a ledge, in a tree hole or in a disused nest. Breeding begins April to may. The clutch of 3 – 6 eggs is incubated by the female and the chicks hatch after 27 – 31 days. The eggs measure around 39 millimetres by 32 millimetres.

What is the kestrel habitat?

Inhabits any kind of open or semi-open situation, from forest clearings to farmland to desert, wherever it can find adequate prey and some raised perches. In breeding season, may be limited to habitats that also provide appropriate nesting sites.

How do kestrels nest?

American Kestrels nest in cavities, although they lack the ability to excavate their own. They rely on old woodpecker holes, natural tree hollows, rock crevices, and nooks in buildings and other human-built structures. Typically, nest sites are in trees along wood edges or in the middle of open ground.

Where do Kestrels make nests?

Kestrels will nest in tree cavities and disused crows nests, but they can be persuaded to settle in to nest boxes. They do not build a nest but will scrape a small dent into the debris lining the bottom of the nest and lay their eggs here.

How long do Kestrels take to fledge?

around four weeks old
The chicks fledge gradually when they are around four weeks old. They explore increasing distances from the nest, but return to it to roost for another couple of weeks. Adults continue to feed the young for a month after fledging, during which time they will learn to catch their own food.

How many eggs does a kestrel lay?

Malagasy kestrel: 4 – 6Kestrel / Clutch size

Do Kestrels live in pairs?

Kestrels are largely monogamous, and while a pair will separate over winter, they will come back together at the turn of the year when the male shows the female around potential sites, often in an area where they have nested before.

How long does it take for a kestrel to fledge?

Fledging occurs about 30 days after they hatch, often over a period of several days. Young kestrels depend on their parents for food for two to three weeks after they fledge.

Do male kestrels sit on the nest?

Usually it is only the female kestrel that incubates the eggs, although in the early days males can sit on them for short periods.

Where do you place a kestrel nest box?

For best results boxes should be sited 3-5 metres up fixed to the side of a tree or sitting in the junction of a branch. Kestrels like an open approach to their boxes, coming in low and preferring to be able to see the box from a distance. It is best to position the opening away from the prevailing wind.

Which direction should a kestrel nest box face?

You may use a pole if a tree is unavailable. Kestrels are less likely to be hit by traffic than species such as Barn Owls, so a position near light traffic is acceptable if other sites are not available. The box should ideally face East or NE/SE.

Where do American kestrels nest?

American Kestrel. In open country it is commonly seen perched on roadside wires, or hovering low over a field on rapidly beating wings, waiting to pounce on a grasshopper. Kestrels nest in cavities in trees; in places where there are few large dead snags to provide nest sites, they may rely on nesting boxes put up for them by conservationists.

What is the lifespan of an American kestrel?

The American kestrel is not long-lived, with a lifespan of <5 years for wild birds. The oldest banded wild bird was 11 years and 7 months, while captive kestrels can live up to 14–17 years. In a study, humans accounted for 43.2% of 1,355 reported deaths, which included direct killing and roadkills,…

Do kestrels migrate north or South?

In North America, the tendency for kestrels to migrate decreases from north to south, with southernmost populations resident year-round. While some American Kestrels migrate to Central America, the great majority spend the winter in the southern United States.

Is the American kestrel related to the American Falcon?

Based on appearance and behavior it was for many years considered a member of the primarily European and African kestrel clade within the genus falco, but DNA analysis shows the American kestrel to actually be genetically more closely related to the larger American falcons such as the aplomado, peregrine, and prairie falcons.
