We report aberrant plumages in seven species of migratory waders (shorebirds) seen in Australia over the past 25 years: Bar-tailed Godwit, Limosa lapponica, Black-tailed Godwit Limosa limosa, Great Knot Calidris tenuirostris, Red-necked Stint Calidris ruficollis, Sharp-tailed Sandpiper Calidris acuminata, Curlew Sandpiper Calidris ferruginea and Double-banded Plover Charadrius bicinctus. Evidence that a leucistic Bar-tailed Godwit and a Double-banded Plover with diluted plumage each lived for at least seven years suggests that some plumage aberrations may not have an adverse effect in survival.
