Dark-sided Flycatcher Muscicapa sibirica in the Cocos (Keeling) Islands

Abstract

A Dark-sided Flycatcher Muscicapa sibirica was observed and photographed on Home Island, Cocos (Keeling) Islands, on 6–7 November 2008. Its identification was based on its compact shape, its very dark, diffusely streaked breast and flanks, its wing-length and primary projection, its short bill with concave sides, prominent white half-collar, asymmetrical eyering and other features. The field marks which distinguish this species from similar-looking Muscicapa flycatchers are discussed. This is the first record of this species for the Cocos (Keeling) Islands and the second (and first photographic) record for Australian territory (Birds Australia Rarities Committee Case no. 593).
