The alder flycatcher (''Empidonax alnorum'') is a small insect-eating bird of the tyrant flycatcher family. Adults have olive-brown upperparts, browner on the wings and tail, with whitish underparts; they have a white eye ring, white wing bars, a small bill and a short tail. The breast is washed with olive-grey. The upper part of the bill is grey; the lower part is orangish. At one time, this bird was included with the very similar willow flycatcher in a single species, "Traill's flycatcher". Their breeding habitat is deciduous thickets, often alders or willows, near water across Canada, Alaska and the northeastern United States. They make a cup nest low in a vertical fork in a shrub. These birds migrate to South America, usually selecting winter habitat near water. They wait on a perch near the top of a shrub and fly out to catch insects in flight, also sometimes picking insects from foliage while hovering. They may eat some berries and seeds. This bird's song is a wheezed ''ree-BEE-a''. The call is a quick ''preet''. ==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「Alder flycatcher」の詳細全文を読む スポンサード リンク
