rorýs skvrnolící Cypseloides cherriei

Little-known swift found mostly in mountainous areas, though flocks occasionally venture into lowlands. All dark with short square tail and angular wings. Namesake white spots on forehead and behind eyes are distinctive, but these can be extremely difficult to see. Many swifts are best left unidentified. Sex and age variation not well known; some birds, maybe juveniles, can show whitish scaling on belly. Occasionally seen singly or mixed with flocks of other swifts, but most often in monotypic flocks of up to several dozen individuals. Voice can be helpful with practice; typically a staccato chatter followed by “pew pew pew” notes like a laser gun.
