Spoonbills began breeding in the UK in 1999 after a 300-year absence and numbers are slowly increasing. Their welfare depends on undisturbed shallow coastal lagoons and estuaries with sufficient fish and invertebrate prey.
Spoonbill breeding colonies disturbed by photographers or recreational visitors experience nest abandonment and chick mortality. Pairs nesting in shallow scrapes are particularly vulnerable to flooding events and predation during the incubation period. Adequate fish and invertebrate prey availability in adjacent wetlands determines chick growth and fledgling success. Each breeding pair represents a significant proportion of the still-small UK breeding population.
