Avocets have recovered spectacularly on UK nature reserves. Managing breeding colonies to reduce predation and disturbance maximises welfare and productivity.
Avocet breeding welfare on managed reserves is substantially better than it would be without active management. Electric fencing around nesting areas prevents fox and mink access, reducing nest failure. Island nesting sites surrounded by water reduce mammalian predator access. Maintaining optimal water levels at 5-10 cm depth supports the shallow wade feeding of chicks. Disturbance management preventing public and drone access to colony areas during incubation and chick rearing maintains adult attendance at nests, preventing chilling and predation.
