Its European breeding population is relatively small (<23,000 pairs), but was stable between 1970–1990. Despite declines in Greece and Croatia during 1990–2000, the species was stable or increased elsewhere within its European range, and probably remained stable overall. Although it was previously classified as Rare, the species’s European breeding population is now known to exceed 10,000 pairs, and consequently it is provisionally evaluated as Secure.
