Description

The Goshawk is a well-built hawk that is widespread but scarce and elusive bird that is usually found in woodlands.

They look like a large Sparrowhawk, but in fact the female Goshawk is about the size of a Buzzard and the male Goshawk is slightly bigger than a female Sparrowhawk.

Both sexes have close horizontally barred underparts and a broadly barred grey tail. The broad whitish eyebrows (supercilia) and piercing orange-yellow eyes make the Goshawk evil-looking. The cere (flesh at the base of the bill) is greenish-yellow and the legs are yellow.

The male (or tercel) is smaller than the female and has a dark patch behind the eye that makes it appear even more fearsome. The female (or falcon) is browner than the male and is the heaviest bird of the genus Accipiter.

Juveniles are paler and browner, with teardrop marks on its underparts and greenish eyes.

In flight, the Goshawk has broad, blunt wings and a broad tail.

Voice

  Quicktime mp3

The Goshawk's call is a penetrating shriek, "hi-aa".

Feeding

Their food is mainly medium-sized birds, such as Wood Pigeons, Pheasants and even Kestrels, mammals, such as rabbits and squirrels, and amphibians and reptiles.

The attack is usually similar to that of the Sparrowhawk - waiting in cover to launch a surprise attack involving a fast chase over a short distance - but will also dive like a Peregrine.

Nesting

Goshawks nest high up in trees and it is the male that does the building. The nest is an untidy construction of twigs lined with bark.

The eggs are about 59 mm by 44 mm, smooth and non-glossy, and pale bluish-white. Incubation is by the female only. Both adults feed the young birds, though the newly-hatched are usually fed by the female with the male hunting and bringing the food to the nest.

Movements

Apart from juveniles dispersing from their natal sites in late summer, Goshawks are sedentary.

Conservation

The Goshawk is slowly expanding its range, helped by management of forests, but despite being specially protected throughout the year it remains one of our most persecuted birds of prey.

My Garden

Graph of garden visits.

The weather in autumn 1998 was quite awful, as Britain experienced the leftovers of the hurricanes, and this upset the rhythm of many birds. The Goshawk, it seems, was one of them. There was a report in BTO's "The Bird Table" of a Goshawk in a garden in Gwynedd (Wales) in late September 1998. The Goshawk that visited our garden in late October was a juvenile. After scaring all the other birds off, it just sat on the fence for about half an hour before flying off again.
