Nonbreeding plumage is paler and grayer than smaller and chunkier Common Redshank. In flight often appears dark overall with narrow white oval up middle of back. Breeds in arctic bogs and swamps; migrants occur in varied wetland habitats. Usually seen as singles or small groups, though will sometimes congregate in large flocks, especially on wintering grounds. Feeds mainly by wading in fairly deep water, probing and picking with its bill, at times swimming.

Cacatua pastinator

Small cockatoo with long pointed bill and a solid, short crest, typically found in farmland. This species is restricted to southwestern Australia, though not usually in the Perth area. Entirely white with pink patch in front of the eye, which has pale blue skin around it. Compare Little Corella (with much shorter bill and crest) and Long-billed Corella (introduced to Perth area from eastern Australia, with red patch on chest and much shorter crest). Call a worried-sounding, wavering cry, slightly lower in pitch than Little Corella’s and less clipped than Long-billed Corella’s.
