Hobby Welfare and Summer Conservation in the UK

Key Facts

• Hobbies arrive in the UK in May and depart by October, breeding in mature woodland edges with open foraging habitat
• They are specialist predators of large dragonflies and hirundines (swallows, swifts, martins)
• UK breeding population of approximately 2,800 pairs has been relatively stable in recent decades
• Hobbies nest in old crow or magpie nests — they never build their own
• Climate change is extending the dragonfly season, potentially benefiting hobby foraging success

Welfare Considerations

Hobby welfare and conservation are closely tied to the ecological health of their foraging habitats: lowland heathland, wetlands, and open farmland supporting dragonfly and hirundine populations. They are not threatened at the UK level but face pressures from agricultural intensification reducing prey abundance and nest site availability. Disturbance at nest sites from birdwatchers and photographers causes nest abandonment. The hobby is an indicator of landscape quality — a territory supports a rich web of prey species, all of which benefit from the same habitat management.

What You Can Do

• Never photograph or observe hobbies at the nest — disturbance causes abandonment
• Support heathland and wetland management that maintains dragonfly populations as hobby food
• Create and maintain wildlife ponds to support dragonfly populations in rural and suburban areas
• Report hobby breeding territories to BTO BirdTrack for population monitoring
• Maintain rough grassland and farmland margins to support hirundine prey for foraging hobbies
