Discussion Confusingly similar to Willow, and both species favor damp woodland. Best identified by voice; silent birds are often not separable. See Willow's entry for discussion of subtle structural differences. Engages in aerial sorties from perches near top of tree after flying insects; also hovers and gleans insects from foliage. Sexes are similar.
