Brown-cheeked Rail

Brown-cheeked Rail (Rallus indicus) is a slender rail with a long reddish bill, brown cheek stripe, grey face and barred flanks. Body shape, bill structure, plumage pattern and voice provide the strongest field characters. Age, sex and season may alter its appearance, so identification should combine several features and careful direct field comparisons with similar species in the same habitat (Wikipedia, general species account).

It breeds in reedbeds of northeastern Asia, winters farther south and probes wet mud for invertebrates. Its movements and social behaviour vary through the year, with breeding birds generally more dispersed and non-breeding birds gathering where food is concentrated. Japanese records place it within the country's documented avifauna as a resident, migrant or visitor (Wikipedia, general species account; Wildlife of Japan occurrence records).
