Black Stork (Ciconia nigra)
Great Black-backed Gull (Larus marinus)
Similar to White Stork (Ciconia ciconia), but with dark brown, metallic neck, head, breast and back. Only belly and innermost, under wing coverts are white. Legs, eye-ring and bill deep red. Flies with neck extended like White Stork, but contrasting white belly is visible at great distance. Immature birds duller brown than adults, with grey-green bill and legs.
Sound:Thin, disyllabic "ahhh-li" heard at nest and when courting. One syllable sounds like gasping intake of air, the other is a thin, piping sound. A bit like a cheap, manual, air-mattress pump. Bill-clattering used by juveniles in alarm.
