Eurasian Collared Dove

Eurasian Collared Dove (Streptopelia decaocto) is a pale grey-buff dove with a narrow black half-collar on the hindneck and dark-tipped tail. The combination of body shape, bill structure, plumage pattern and voice provides the most useful field characters. Age, sex and season can alter its appearance, so identification should use several features rather than colour alone. This supports comparison with similar species in the field (Wikipedia, general species account).

It feeds on seeds and grain in open country and settlements and has expanded far beyond its original Asian range. Its movements and social behaviour vary through the year, with breeding birds generally more dispersed and non-breeding birds more likely to gather where food is concentrated. Japanese records place it within the country's documented avifauna as a resident, migrant, visitor or introduced bird (Wikipedia, general species account; Wildlife of Japan occurrence records).
