Nuthatch (Sitta europaea)
Lesser Black-backed Gull (Larus fuscus)
Unmistakable in most of Europe where no other nuthatch species occur. Only bird climbing head-first downwards trees. Blue-grey upperparts, white underparts and solid black eye stripe. Large head, long bill and short tail. Climbs in jerky, but nimble motion. Scandinavian birds with mostly white underparts (except for vent), continental birds with more rufous belly.
Sound:Very varied voice. Ranging from very high pitched whistles and melodic resonant calls, to chattering and nasal mocking sounds. Song a simple series of loud notes. Characteristic warning call a hard "check" or "chwit", often in rapid series, like a pebble bouncing on hollow ice.
