Northern beardless tyrannulet

The northern beardless tyrannulet (Camptostoma imberbe) is a small passerine bird in the tyrant flycatcher family.

It breeds from southeasternmost Arizona and Texas of the United States through Mexico and Central America to northwestern Costa Rica.

Sexes are similar, and this species always appears not as bright, especially with regard to the wing bars, as the closely related southern beardless tyrannulet, C. obsoletum, with which it was once considered conspecific.

Northern beardless tyrannulets are active birds, feeding in a vireo or warbler-like fashion on insects, spiders and berries.

In courtship, or when alarmed, the crests are raised, the tail flicked, and an excited call is made.
