Habitat & Distribution

Sparrowhawks are widely distributed across Europe and Asia, from the British Isles to Japan and south to Tanzania in East Africa. They inhabit a variety of wooded habitats, including deciduous and coniferous forests, parks, and large gardens.

In the UK, Sparrowhawks are resident year-round and can be found in most areas with suitable woodland cover. Some northern populations may move south during harsh winters, while others remain in their breeding territories.

They are one of the UK's most common birds of prey, with a population estimated at over 60,000 mature individuals.

Diet

Sparrowhawks primarily hunt small to medium-sized birds, with species like finches, tits, and thrushes forming the bulk of their diet. The smaller males generally eat birds like sparrows and tits, while the females can subdue larger prey like starlings, thrushes, and even pigeons.

They are skilled hunters, often catching prey in flight or by ambushing them in dense cover. Occasionally, they may take large insects or small mammals, like rodents, bats and reptiles.

Behaviour

Sparrowhawks are known for their swift, agile flight through woodlands. They often employ a 'flap-flap-glide' pattern when hunting, using cover to surprise prey.

During the breeding season, males perform spectacular sky dances, making steep dives and climbs to attract females.

Calls & Sounds

Sparrowhawks are generally silent outside the breeding season. During courtship and nesting, they become highly vocal and produce a rapid, high-pitched 'kew-kew-kew' call.

When alarmed, they emit a sharp, piercing 'kik-kik-kik'. Females have a louder, more guttural call compared to males.

Nesting & Breeding

Sparrowhawks typically breed between April and August. Males perform elaborate aerial displays to attract females, including high circles and steep dives. Once paired, they often reuse the same nesting site for years.

Nests are constructed by both sexes, usually in a fork of a tree near the trunk. They are made of twigs and lined with bark flakes. Females lay 4-6 pale blue eggs with brown speckles.

Incubation lasts about 33 days, primarily done by the female while the male provides food. Chicks fledge after 24-30 days but remain dependent on their parents for several weeks after leaving the nest.

Conservation

While currently listed as Least Concern, Sparrowhawks faced historical declines due to pesticide use in the mid-20th century.

They have since recovered in many areas but still face threats from habitat loss and illegal persecution. Ongoing monitoring is crucial to ensure their continued recovery.

Additional Details

Predators:
Adult Sparrowhawks have few natural predators, but they may fall victim to larger raptors like Goshawks or Eagle Owls. Nestlings and eggs are vulnerable to corvids, squirrels, and pine martens.

Birdwatching Tips

  • Look for Sparrowhawks in woodland edges or gardens, especially near bird feeders
  • Listen for alarm calls from small birds, which often indicate a Sparrowhawk's presence
  • Watch for their characteristic low, fast flight, with a few quick wingbeats, between trees
  • In the UK, observe local parks or wooded areas during early morning or late afternoon
  • Males tend to hunt more in woodland, females more in fields and open spaces
