The yellow-billed shrike (''Corvinella corvina'') is a small passerine bird in the shrike family. It is sometimes known as the long-tailed shrike but this is to be discouraged since it invites confusion with the long-tailed shrike, ''Lanius schach'', of tropical southern Asia. The yellow-billed shrike is a common resident breeding bird in tropical Africa from Senegal east to Uganda and locally in westernmost Kenya. It frequents forest and other habitats with trees. The nest is a cup structure in a bush or tree into which four or five eggs are laid. Only one female in a group breeds at a given time, with other members providing protection and food. The yellow-billed shrike is 18 cm long with a long tail and short wings. The adult has mottled brown upperparts and streaked buff underparts. There is a brown eye mask and a rufous wing patch, and the bill is yellow. Sexes are similar, but immatures show buff fringes to the wing feathers. This is a conspicuous and gregarious bird, always seen in groups, often lined up on telephone wires. It is noisy, with harsh ''swee-swee'' and ''dreee-too'' calls. The yellow-billed shrike feeds on insects which it locates from prominent look-out perches in trees, wires or posts. ==References== * ''Birds of The Gambia'' by Barlow, Wacher and Disley, ISBN 1-873403-32-1 * 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「Yellow-billed shrike」の詳細全文を読む スポンサード リンク
