Abstract

Four partly albino fledglings were observed in two Carrion Crow Corvus corone orientalis families in Hirosaki City, Aomori Prefecture, Japan, from 30 June to 9 August 2002. They all had white parts on the subterminal regions of the upper and under primary coverts, upper and under greater coverts, primaries, secondaries, and tertiaries. Two fledglings in one family had white in the subterminal regions of the rectrices as well as in the remiges. The latter two birds stayed with their parents for about 20 days longer than their single normally plumaged sibling.
