What is the general social grouping structure of Costa's Hummingbirds outside of mating interactions?

Answer

Generally solitary creatures that do not form flocks

Outside of the intense, brief periods associated with mating rituals, the social dynamic of the Costa's Hummingbird is decidedly solitary. They are not known to aggregate into stable groups. While temporary, tense tolerance might occur around a rich food source like a backyard feeder, they do not form cooperative groupings or flocks. After breeding concludes, they disperse to focus solely on solitary foraging.
