CRC Press (1992), ISBN 978-0-8493-4258-5.〕 Females are larger than males and Northern populations are notably larger than Southern races.〔() (2011).〕 Adults are larger than whiskered screech owls, with larger feet and more streaked plumage pattern. There are several morphs: brown Pacific, grey Pacific, Great Plains, Mojave, and Mexican. All have either brown or dark gray plumage with streaking on the underparts. There is no red morph. They have a round head with ear tufts, yellow eyes and a yellowish bill. Their appearance is quite similar to whiskered and eastern screech owls, so it's best to identify them by their calls. They were previously considered to be the same species as the eastern screech owl.〔''The Sibley Guide to Birds'', by David Allen Sibley, ISBN 0-679-45122-6〕 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「Western screech owl」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
