The yellow-throated vireo (''Vireo flavifrons'') is a small American songbird. Adults are mainly olive on the head and upperparts with a yellow throat and white belly; they have dark eyes with yellow "spectacles". The tail and wings are dark with white wing bars. They have thick blue-grey legs and a stout bill. Their breeding habitat is open deciduous woods in southern Canada and the eastern United States. These birds migrate to the deep southern United States, Mexico, and Central America. They are very rare vagrants to western Europe; there is a September 1990 record from Kenidjack Valley in Cornwall, Great Britain, and September 1998 record from Heligoland, a small German archipelago in the German Bight.〔 They forage for insects high in trees. They also eat berries, especially before migration and in winter when they are occasionally seen feeding on gumbo-limbo (''Bursera simaruba'') fruit.〔Foster, Mercedes S. (2007) The potential of fruiting trees to enhance converted habitats for migrating birds in southern Mexico. ''Bird Conservation International'' 17(1): 45-61. (PDF fulltext )〕 They make a thick cup nest attached to a fork in a tree branch. ==References== ==External links== *(Yellow-throated Vireo Species Account ) - Cornell Lab of Ornithology *(Yellow-throated Vireo - ''Vireo flavifrons'' ) - USGS Patuxent Bird Identification InfoCenter *(Yellow-throated Vireo Bird Sound ) 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-throated vireo」の詳細全文を読む スポンサード リンク
