Hobby Welfare: A Summer Falcon on UK Heathland

The hobby is Britain's most agile falcon, arriving in summer to breed — individual welfare depends on insect and small bird prey availability.

Key Facts

• Hobbies arrive from sub-Saharan Africa in late April to breed in southern and central England
• They prey primarily on large insects and small passerines caught in aerial pursuit
• Nest sites are invariably old crow nests in trees near heathland or wetland
• Climate change appears to be extending hobby range northward as conditions warm
• Hobbies are extremely sensitive to nest disturbance causing abandonment if closely approached

Welfare Considerations

Hobby welfare during breeding depends on the availability of large aerial insects, particularly dragonflies and large beetles, and small passerines as prey. In warm, insect-rich summers hobbies thrive — food is abundant and chick-rearing is successful. In cold, insect-poor summers hobbies must travel further for food and may struggle to provision chicks adequately. Nest disturbance by birdwatchers or photographers approaching crow-nest nest sites causes abandonment — pairs that have invested weeks in courtship, territory establishment, and incubation lose their entire breeding attempt. The expansion of hobby range northward with warming climate means welfare-positive habitat management in new areas increasingly benefits this spectacular falcon.

What You Can Do

• Observe all hobby nest sites from considerable distance — do not approach active nests
• Report hobby nesting locations to local birding groups for discreet recording
• Reduce insecticide use to maintain the large insect prey hobbies depend on
• Support heathland and wetland conservation that maintains hobby foraging habitat
• Record hobby sightings through BTO surveys to monitor the northward range expansion
