Behavior

Territoriality

Males defend clumps of flowers from conspecific males and hummingbirds of other species. They are thought to willingly share feeding domains with conspecific females only during courtship (Feinsinger and Chaplin 1975, Snow 1977, Feinsinger et al. 1988). Females also show territorial behavior, but they are less aggressive and use scattered bunches of flowers in a manner termed 'traplining' (Feinsinger and Chaplin 1975).

Sexual Behavior

Little courtship behavior has been described for this species, although the sexes occasionally share flowers and call to each other responsively (Snow 1977). Because males and females typically exclude each other from defended feeding territories, it has been suggested that such atypical resource sharing is a form of courtship.
