Remsen, J.V. 1978 Allen's Hummingbird Selasphorus sasin Mar. 18 Pt. Reyes, Marin Co. Calif.: A male was watched displaying directly to a female in some open undergrowth adjacent to the stream next to the Pt. Reyes hdqts. area. The male had given one complete pendulum display and then flew to within a foot of a female (which we had not seen) carrying some white fluff. The female retreated a foot or so and the male began darting back and forth at her with tail cockled and spread and gorget extended: tail cockled, spreard vertical --> gorget extended spread held out from throat The hovering zigzagged back and forth in front of the female, moving directly at her and then back, then at her again, etc., all in rapid succession. Presumably the female's view would look something like this: The male is maximizing the area of rufouse exposed to the female - the tail spread display reminiscent of Sase Group. Perhaps the moving back and forth in front of the female maximizes the flashing effect of the iridescent gorget.
