marshall (1942) Chaetura richmondi? Luke Olomega jan 22 several noted at olomega landing in am. small - black. V. de Santa Ana : See Gordon article. Courtship took place over fixed circuit along main canyon up Cerro del Aguila & around through certain large trees there - at terrific speed. The flocks of Streptoprocne and Chaetura never mixed here as far as I could tell, altho they would appear at the same places at different times. Charles: Chilata - Courtship flight by pairs only, seen among balsam groves. Flocks would mix with Streptoprocne over grassy knoll in late afternoon. Call note - vigorous staccato 'kip, kip, kip, trip,' given especially when chasing each other in circuits around trees. Call heard overhead before swift come into view. Becomes more intense & twanging in courtship - almost like call of Eutamias. Only single notes.
