"Guatemalan tyrannulet," Wikipedia, the free encyclopedia. The Guatemalan tyrannulet or paltry tyrannulet, is a very small passerine bird in the tyrant flycatcher family. It occurs in southern Mexico, Guatemala, El Salvador and southern Belize. It was formerly considered to be conspecific with the mistletoe tyrannulet (Zimmerius parvus). The Guatemalan tyrannulet is a common bird from the lowlands to 2,600 m (8,500 ft) altitude, mainly in humid regions. It can be found in forests, second growth, pasture and plantations with trees, and shady gardens.The Guatemalan tyrannulet is 11–12 cm (4.3–4.7 in) in length. The upperparts are olive-green other than a dull grey crown to the head and grey supercilia. The wings are blackish with yellow feather edging but no wing bars, and the longish tail is dusky. The throat and breast are off-white with grey streaking, the belly is white, and the flanks have a dull yellow-green cast. The long legs are blackish. The sexes are similar, but young birds have an olive crown, yellow-tinged supercilia and broader but paler wing bars. The call is a loud peeer and the dawn song is a plaintive yer-de-dee, yer-de-dee.
