White-backed Woodpecker (Dendrocopos leucotos)
Black-throated Loon (Gavia arctica)
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".

Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.
