WHITE-CRESTED TYRANNULET Serpophaga subcristata
The White-crested Tyrannulet is a winter visitor to Paraguay when it can be quite numerous, even in urban areas. They are restless, active feeders, rarely still for more than a second, taking a variety of tiny insects both in flight and gleaned from foliage. It is part of a recently discovered cryptic species complex with another, as yet unnamed, but extremely similar species.

Identification of non-vocalising Serpophaga tyrannulets is difficult. Typically this species has an unbroken supercilium and a white crest bordered black that is sometimes visible in the field. The crest can be hidden, but its presence is diagnostic.
Serpophaga subcristata calls from a pair recorded Aguara-Ñu, Mbaracayú Biosphere Reserve, Departamento Canindeyú (Juan Mazar Barnett November 1997).
