Tyrant-flycatchers (Tyrannidae)

Say's Phoebe (Sayornis saya) - HBW 9, p. 374

French: Moucherolle à ventre roux German: Zimtbauch-Phoebetyrann Spanish: Mosquero Llanero

Taxonomy: Muscicapa saya Bonaparte, 1825, Arkansaw River, near Pueblo, Colorado, USA.
Taxonomy yet to be fully resolved, and analysis confounded by problems of wear and fading in museum specimens. Geographical variation in colour weak, perhaps clinal, with paler coloration in arid environments. Birds from Alaska and NW Canada described as race yukonensis and those of Mexican Plateau as pallida; both merged with nominate, although further research may indicate that one or both should be upheld. Two subspecies currently recognized.

Subspecies and Distribution:

  • saya (Bonaparte, 1825) - N Alaska S through W & WC USA to C Mexico; winters from S USA (California E to Texas) S to C & S Mexico.
  • quiescens Grinnell, 1926 - NW Mexico (N Baja California and Cedros I).
