Great Grey Shrike: Winter Visitor Welfare Science

Key Welfare Facts

Great grey shrikes are solitary territorial winter visitors to heathland and open farmland in the UK.
Each bird establishes a winter territory and defends it aggressively against conspecifics and other predators.
They create larder caches of impaled prey on thorns and barbed wire, supporting welfare through food security.
Winter welfare depends on prey availability including voles, large insects, and small birds in open habitats.
Heathland management maintaining open structure with scattered scrub provides optimal shrike foraging habitat.
Disturbance by birdwatchers at larder sites causes birds to abandon cached food representing significant energy loss.

Welfare Assessment

Great grey shrike welfare benefits from maintaining open heathland with diverse prey populations and respectful birdwatching practices that avoid disturbing larder sites. Supporting heathland management funds the habitat these spectacular winter visitors need.
