Say's phoebe (Sayornis saya) is a passerine bird in the tyrant flycatcher family, Tyrannidae.

Say's phoebe was formally described in 1825 by the French naturalist Charles Lucien Bonaparte from a specimen collected near Pueblo, Colorado.

He coined the binomial name Muscicapa saya where the specific epithet was chosen to honour the American naturalist Thomas Say.

[6] They winter in the desert southwest to southern Texas and south through Mexico to northern Central America.

It is made of grass, forbs, moss and plant fibers lined with hair and other fine materials.

The diets of adult Say's phoebes varies from that of nestlings, with the latter consuming a higher share of soft foods.

[12] Like other Sayornis species, Say's phoebe is known to use "song-like" displays as its main form of communication.

[13] This initial peak pitch is a distinctive trait to Say's phoebe compared to its other Sayornis counterparts.

They generally use this form of communication to countersing other birds, make its presence known when patrolling its territory, and in during the early stages of mating season.
