The bridled titmouse (''Baeolophus wollweberi'') is a small songbird, a passerine bird in the tit family Paridae. These birds range from 11.5 – 12.7 cm. (4.5 to 5 in.) long. It is small, crested and gray with a black and white patterned face, a black bib. Its crest is boarded with black and white (sometimes gray) underparts. A standard nest ranges from 5 – 9 eggs colored white, speckled, or reddish-brown.〔Book of North American Birds. Pleasentville: Readers Digest, 1990. pg 232.

They nest in a hole in a tree, either a natural cavity or sometimes an old woodpecker nest found 4 – 28 ft. off the ground. They line the nest with soft materials. Usually built from loose cups of cottonwood down, stems, leaves, and grass.〔Book of North American Birds. Pleasentville: Readers Digest, 1990. pg 232. Print.〕 These birds are permanent residents and may join small mixed flocks in winter. They forage actively on branches, sometimes on the ground, mainly eating insects, especially caterpillars, but also seeds, nuts and berries. They will store food for later use. The song is usually described as a whistled ''pidi-pidi-pidi-pidi''. They make a variety of different sounds, most having a similar tone quality. ==References== 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「Bridled titmouse」の詳細全文を読む スポンサード リンク
