Zusammenfassung Das Brutkleid des weiblichen Mauerläufers wird in der Literatur unrichtig beschrieben. Danach soll es dem ♂ ähnlich, nur blasser sein. Die Beobachtungen von 16 Junge fütternden ♀ zeigte, daß 5 ♀ eine weiße Brust hatten wie im Winterkleid. Die übrigen 11 ♀ hatten einen isolierten, von weißen Feldern umgebenen schwarzen Fleck, der bei 10 ♀ klein, bei nur einem ausgedehnter war. Die Kehle war bei allen ♀ weiß. Der lrrtum wird damit erklärt, daß Mauerläufer im Brutkleid nur sehr selten in den Sammlungen der Museen zu finden sind.
Abstract:
Summary The breeding plumage of female Wall-creepers is incorrectly given in literature, which describes females as similar to males, but paler. The observation of 16 females feeding young showed that 5 had a white breast, as in winter plumage. The other 11 had an isolated black spot surrounded by white; the black spot on 10 being small, and larger only on one. The throats of all 16 females were white. The oversight in the literature is explained by the lack of specimens of females in the breeding plumage in museum collections.
Notes:
Summary Description of a new subspecies of the Black-masked Finch,Coryphaspiza melanotis marajoara, from Marajó Island, Pará, in the mouth of the Amazon. This bird was not previously known north of Goiás, Central Brazil. Its presence on Marajó may be a parallel to that of the Red-winged TinamouRhynchotus rufescens and could indicate that the savannas, where these birds live, are natural ones, and have not been produced by men. Some fieldnotes on the Black-masked Finch are added.
