Sparrowhawks are often briefly seen as they dart between trees or pursue their prey. Read on to learn how to distinguish between the sexes and which other species they resemble.
Sparrowhawks are dove/pigeon-sized birds of prey with small heads and long tails. They have short, hooked bills and long legs with large feet and talons. Female Sparrowhawks are brown above and white below with brown barring. Their eyes and legs are yellow, and they have a pale eyebrow stripe (supercilium).
Males are smaller and more colourfully marked than their female counterparts. They can be identified by their grey upperparts and white underparts with red-brown barring. The same reddish shade often covers their cheeks, throat, flanks, and the sides of their chest. They have yellow legs and yellow to orange eyes.
Juvenile Sparrowhawks resemble adult females but have bolder brown barring on their underparts.
Sparrowhawks could be confused with other UK birds of prey like the Kestrel, Merlin, or the larger Goshawk. Males may also be confused with the Cuckoo.
Male Sparrowhawk
Female Sparrowhawk
Sparrowhawks are small birds of prey with short, broad wings. Females are noticeably larger (16-20%) than males.
Both sexes measure 28 to 40 cm long.
The Sparrowhawk has a surprisingly wide weight range. Most females weigh 185 to 350 grams, while males weigh between 105 and 196 grams.
There is also a significant difference in male and female wingspans. Male Sparrowhawks measure 56 to 65 centimetres between the wingtips, while females measure 65 to 78 centimetres.

Only ten percent of the sparrowhawk’s hunting attacks are successful.
Sparrowhawks are usually quiet and unobtrusive, although they can be highly vocal when nesting. Read on to learn more about their calls.
Sparrowhawks produce a loud ‘ke-ke-ke-ke’ or ‘kew-kew-kew’ call. Young birds have a softer, more drawn-out begging call.
Sparrowhawks are most vocal during the breeding season and when near their nests. They call to maintain contact with their partner and family, and hungry young birds call to beg for food.

Sparrowhawks are specialised hunters. Their short wings allow them to fly through narrow spaces at high speeds to surprise their prey.
Sparrowhawks hunt other birds and their young. The smaller males generally eat birds like sparrows and tits, while the females can subdue larger prey like starlings, thrushes, and even pigeons. They occasionally take other prey like rodents, bats, reptiles, and insects.
Check out our full guide on the diet of a Sparrowhawk as well as our Sparrowhawk hunting behaviour guide.
Baby Sparrowhawks eat strips of bird meat supplied by their mother. The male brings in most of the food, although he catches smaller prey. Young birds become independent when they are about two months old.

The sparrowhawk has been used in hunting for centuries.
Sparrowhawks are generally shy and elusive. However, these birds are widespread in the UK, and birdwatchers always have a chance of spotting them in their preferred habitats.
Sparrowhawks are most at home in woodlands, although they frequent gardens and parks. They will also venture into more open country to hunt over meadows and wetlands, particularly in the non-breeding season.
Sparrowhawks occur in suitable habitats throughout the United Kingdom and Ireland. They are also very common in Scotland, although largely absent from the highlands. Elsewhere the species occurs east to Russia’s Kamchatka Peninsula and Japan, and south to Tanzania in East Africa.
Check out our full guide on where Sparrowhawks live.
Sparrowhawks spend most of their time in trees. They are not particularly comfortable on the ground, although they may pluck larger prey and feed there. Sparrowhawks do not spend much time in flight, although they will engage in conspicuous and acrobatic flight displays at the start of the breeding season.
Sparrowhawks are mainly found in woodland
Sparrowhawks are territorial birds that do not occur in high numbers. However, these widespread birds are one of the United Kingdom’s commonest birds of prey. The UK population is estimated at over 30,000 pairs.
There is always a chance of spotting a Sparrowhawk if you live in a well-wooded area. If not, visit a local woodland where you may spot one darting between the trees. These birds are fairly shy, and sightings are often brief, although good sightings can be had in spring when they display over nesting areas.
Flight characteristic is a few quick wingbeats relieved by a short glide to descend. Flight path is slightly undulating. Often flies low over ground to make surprise attacks.
Female is larger than the male with a steadier flight. Males tend to hunt more in woodland, females more in fields and open spaces.

Sparrowhawks are top predators but have relatively short lifespans due to the ever-present risk of injury and starvation.
Sparrowhawks live between two and three years on average. Their maximum age is around fifteen years.
Adult Sparrowhawks have few natural predators. However, they could fall prey to larger raptors like the Goshawk or Peregrine Falcon, or land animals like the fox, particularly if weakened by hunger or injury. Their eggs and chicks are more vulnerable to predators like martens.
Sparrowhawks are protected in the United Kingdom by the Wildlife and Countryside Act.
Sparrowhawks are not endangered. They have an amber conservation status in the UK but are classed as a ‘Least Concern’ species by the International Union for the Conservation of Nature (IUCN).

Sparrowhawks are breeding residents in the United Kingdom. Each spring and summer, pairs work together to build a new nest and raise a single brood.
Sparrowhawks build their nest in trees in forests and woodlands virtually throughout the UK. The nest is usually built low in a tree, in a fork near an opening where they have easy access.
Sparrowhawk nests are built from twigs and not lined with soft material. They can reach nearly a meter wide and about 30cm deep, although most are smaller.
For a more comprehensive guide, check out our Sparrowhawk nesting article.
Sparrowhawks usually lay three to six eggs, each measuring about 39 millimetres long and 33 millimetres wide. They are a pale blue shade and variably marked with brown spots.
Sparrowhawks form stable partnerships each nesting season, although they generally do not mate for life.

Sparrowhawk behaviour is difficult to observe, although fascinating if you get the chance. Their high-speed hunting technique and acrobatic flight displays make for exciting birdwatching.
Sparrowhawks are aggressively territorial in the nesting season and will not allow other pairs near their nest. They are not aggressive towards humans, but other small birds have much to fear. Sparrowhawks hunt at high speed, flying low and sticking to cover before making the strike.
Like most other birds, Sparrowhawks are highly territorial during the breeding season, and can be very aggressive to other birds
Sparrowhawks are not migratory in the United Kingdom, although specimens that nest elsewhere in Europe and Asia migrate south for the winter. Some birds that migrate from Northern Europe have been recovered in the UK.
Sparrowhawks are a native species in the United Kingdom.
The sparrowhawk is a sacred bird in Slavic mythology.

Sparrowhawks use speed and the element of surprise to catch their prey. They may reach speeds of up to 31 miles per hour (50 km/h) in the moments before they strike.
The Sparrowhawk’s habit of catching garden birds can be rather upsetting to many bird lovers. In this situation, the best thing to do is to place your feeders near dense cover to give the smaller birds a fighting chance at escape. Sparrowhawks need to eat regularly to survive, just like other birds, even if it may be difficult to watch.
