:''For the similarly named Australian bird see Brown treecreeper.'' :''For the similarly named New Zealand bird see Brown creeper (New Zealand).'' The brown creeper (''Certhia americana''), also known as the American treecreeper, is a small songbird, the only North American member of the treecreeper family Certhiidae. ==Description== Adults are brown on the upperparts with light spotting, resembling a piece of tree bark, with white underparts. They have a long thin bill with a slight downward curve and a long stiff tail used for support as the bird creeps upwards. The male creeper has a slightly larger bill than the female. The brown creeper is long. Its voice includes single very high pitched, short, often insistent, piercing calls; ''see'', or ''swee''. The song often has a cadence like; ''pee pee willow wee'' or ''see tidle swee'', with notes similar to the calls. 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 creeper」の詳細全文を読む スポンサード リンク
