Blaukopfamazilie Saucerottia cyanocephala

Medium-sized hummingbird of oak and pine-oak woodlands and adjacent shrubby clearings; also local in lowland pine savannas. Sexes look alike and often look rather dull overall, despite the name. Note the whitish throat and breast offset by a dusky vest, and the dusky brownish rump and tail. Crown and sides of head are blue (rarely catching the light), with a white spot behind the eye and some red at base of bill.
