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.
As part of ongoing research into the conservation of wild avian species in Niigata Prefecture, helminthological examination was conducted between March and November 2002 in Niigata Prefectural Bird Protection Center, Japan. A total of 50 individuals of 28 avian species was investigated, with parasitic helminthes collected from 26 individuals. The parasitic helminths belonged to 13 nematode, two acanthocephalan, and three trematode genera, and unidenfied cestodes were also collected. Three genera, Epomidostomum (host: Anser albifrons), Viktorocara (host: Fulmarus glacialis) and Diomedenema (host: Ardea cinerea) were new locality records in Japan.
