White-backed Woodpecker (Dendrocopos leucotos)
Little Tern (Sternula albifrons)
Upper back strongly barred, lower back all white (barred in south-east Europe subspecies). Underparts streaked. Whole crown red in male. Vent pinkish red, not deep red as in Great Spotted, and less marked. Most likely to be confused with Middle Spotted Woodpecker, but is clearly bigger, has longer bill and black moustache stripe connects to base of bill. Easily recognized in flight due to strong wing-bars and white lower back.
Sound:Drumming noticeably longer and more powerful than Great Spotted, with accelerated ending (similar to Three-toed Woodpecker but faster). Contact call similar to Great Spotted, but slightly deeper and softer; "kjuk".

CCWhite forehead with white wedge above eye in all plumages. Legs, and most of bill yellow in adult breeding plumage. Very small and longwinged tern. Only 2/3 of size of Common Tern. Head and bill proportionally longer than Chlidonias species and congeners, while tail is shorter. Back paler grey and belly whiter. First primaries form a dark front edge to wing. In winter the bill darkens, legs turn a dirty yellow and the white forehead expands. Juvenile resembles adult winter, but has yellowish bill base and scale patterned back. Flight fluttering with rapid wing-beats, which together with size, is usually sufficient to determine the species.
Sound:Fairly distinct voice. Contact call a sharp "kitt", often combined to form undulating, rolling series. Not as sharp and penetrating as Common- and Arctic Tern.
