UK Hobby Hawk Welfare: Breeding Season and Prey Availability

The hobby is Britain's most aerial falcon, famous for catching dragonflies and swallows on the wing. Its welfare depends on healthy insect populations and undisturbed heathland breeding habitat.

Key Facts

Hobbies arrive from sub-Saharan Africa in May and depart by October
Nests are always taken over from other birds, most commonly crows
Dragonflies and swallows form the bulk of the summer diet
Hobby populations have increased slightly in recent decades, bucking the wider raptor trend
Breeding success is closely linked to swallow and swift population trends
UK population is estimated at 2,800-4,000 breeding pairs

Welfare Considerations

Hobbies depend on abundant aerial insect prey to fuel their extraordinary flight performance. Declines in dragonfly populations from wetland loss and swallow populations from farmland change reduce the prey base available to breeding and migrating hobbies. Chicks that cannot be provisioned adequately starve in the nest - an entirely preventable welfare outcome if prey populations are maintained through habitat protection.

What You Can Do

Support heathland conservation and wetland restoration that benefits hobby prey
Contribute hobby sightings to BTO BirdTrack for population monitoring
Advocate for agri-environment funding that supports swallow breeding habitats
Avoid disturbing potential nest sites in woodland near heathland from May to August
Reduce insecticide use that depletes aerial insect populations
