The brown jay (''Psilorhinus morio'') is a large American jay which has the habitus of a magpie, but is slightly smaller and with a shorter tail, though the bill is larger. It occurs from Mexico south into Central America on the Gulf slope. The northernmost extent of the bird is in the Rio Grande Valley of Texas. ==Description== Brown jays vary in plumage geographically: there are two main groups. Northern birds are almost completely dark brown, with lighter brown on the underparts. Southern birds are white-bellied and have bright white tips to the outer tail feathers. The intergrade zone is in Veracruz, Mexico. Adults in both populations have black bills, legs, and feet. Immatures have yellow bare parts, including yellow eye-rings. The voice is a loud but low-pitched ''pee-ah'' call and is often modified to suit its situation or mood. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「brown jay」の詳細全文を読む スポンサード リンク
