Lesser Kestrel Welfare: Colony Breeding and Conservation in Spain

Lesser kestrels breed colonially in old buildings and cliffs across Spain, facing welfare threats from nest site loss, pesticide use, and prey scarcity.

Key Facts

Spain holds the largest European lesser kestrel breeding population
Colonies nest in old buildings, churches, and cliff faces across southern Spain
Agricultural intensification reduces invertebrate prey availability on breeding grounds
Pesticide use in grasslands kills the large insects kestrels depend on
Conservation projects providing nest boxes in villages have boosted local populations

Welfare Considerations

Colonial lesser kestrels face welfare challenges when traditional nest sites in old buildings are renovated or demolished without provision of replacement structures. Prey scarcity caused by pesticide use means parents must travel further to feed chicks, increasing brood starvation risk. Nest sites at high ambient temperatures create heat stress for chicks in poorly insulated buildings during Mediterranean summers.

What You Can Do

Support Spanish lesser kestrel conservation and nest box programmes
Advocate for retention of nest sites when renovating old buildings
Reduce pesticide use in gardens and encourage farmland pesticide reduction
Donate to organisations restoring traditional farmland habitats in Spain
Report lesser kestrel colonies to conservation databases
