The turtle dove has declined by 98% in the UK since 1970 and is now critically endangered. Their welfare depends on specific farmland food plants, quiet nesting scrub and survival on migration routes through Europe.
Turtle doves arriving in the UK from sub-Saharan Africa face a landscape transformed from the cereal-rich farmland their ancestors exploited. Modern herbicide use has eliminated the weed seeds that turtle doves depend on to fuel reproduction. Birds that cannot find adequate food cannot rear sufficient chicks to offset adult mortality. The hunting pressure during migration through southern Europe kills birds that have survived the trans-Saharan crossing and reached breeding condition. Each individual turtle dove that fails to reproduce due to food scarcity on its breeding grounds represents a welfare and conservation loss in a species already at the edge of viability.
