Eurasian spoonbills have recently recolonised the UK as breeding birds after 300 years, but their small population remains vulnerable to disturbance at nest sites.
Spoonbills at small UK breeding colonies are particularly vulnerable to disturbance impacts because each breeding pair represents a significant proportion of the total breeding population. Nest abandonment following disturbance eliminates an entire season's breeding contribution. Chicks require parental care for an extended period and are vulnerable to cold stress during incubation breaks caused by disturbance. The slow population growth means welfare impacts on individual birds have disproportionate conservation significance.
