Degree of Sociality

On occasion, the Hispaniolan Trogon gathers in small flocks for reasons as yet to be determined. One such encounter is described by Wetmore and Swales (1 Wetmore, A., and B. H. Swales (1931). The birds of Haiti and the Dominican Republic. United States National Museum Bulletin 155. Smithsonian Institution, Washington, DC, USA. Close ) in mid April where six birds where seen together: "Two, apparently rival males, were matched in harmless combat in which they rested a few feet apart with head outstretched and tail hanging down. At intervals the tail was raised slowly to nearly a right angle with the back and then brought down rather quickly to its normal perpendicular position. At brief intervals one dashed at the other with a loud rattle of wings but apparently the two never actually struck one another as the one attacking usually passed beneath the opponent. They uttered constantly a rolling note that mingled with the usual cooing calls uttered steadily by their companions." Such aggregations have been reported by other individuals but no research has been conducted to determine what this behavior represents.

The Hispaniolan Trogon may also rarely join mixed-species flocks (29 Latta, S. C., and J. M. Wunderle (1996). The composition and foraging ecology of mixed-species flocks in pine forests of Hispaniola. Condor 98(3):595–607. Close ).

Nonpredatory Interspecific Interactions

Interspecific behavior includes aggressive interactions with the Hispaniolan Woodpecker (Melanerpes striatus) at the nesting cavity (M. Cañizares, personal observations). Whether these interactions are competition for the cavity itself or possible egg or nesting predation is unknown.
