Hobby Falcon Welfare: Aerial Predator of Open Country

The hobby is a graceful summer migrant falcon that breeds across southern and central UK. Its welfare is linked to insect and small bird prey availability and nest site integrity.

Key Facts

The hobby (Falco subbuteo) is a summer visitor to the UK, wintering in Africa
An estimated 2,500-3,500 pairs breed in the UK, predominantly in southern England
Hobbies are aerial specialists catching large insects (dragonflies) and small birds (swallows, swifts) on the wing
They do not build their own nests, instead using old crow or magpie nests in trees
Insect decline threatens hobby welfare through reduced prey availability during breeding season
Climate change is altering the timing of dragonfly and hirundine abundance, potentially creating mismatches with chick rearing periods
Disturbance of nest sites during the breeding season (June-August) can cause nest failure

Welfare Considerations

Hobby welfare is closely tied to ecological health. As specialist aerial insect predators, hobbies are sentinels of ecosystem change. Neonicotinoid insecticides and habitat loss have reduced dragonfly and large insect populations, meaning hobbies face harder foraging conditions than historical populations. Chick welfare during periods of low insect availability is particularly concerning - hungry chicks in the nest cannot thermoregulate effectively and are vulnerable to cold nights. Maintaining wetland habitats that support dragonfly populations is therefore a direct hobby welfare intervention.

What You Can Do

Support pesticide reduction campaigns that protect insect populations important to hobby prey chains
Maintain or restore wetland habitats near farmland to sustain dragonfly populations
Do not disturb known hobby nesting sites from June to August
Report hobby sightings to BTO BirdTrack to contribute to population monitoring
