Even though most hummingbirds in SoCal wing it over to Mexico to spend the winter there, some stay, so that one can watch them all year long. In Spring, however, the main flock returns and one can see them everywhere.
Apart from their amazing flight abilities they also have a major attitude – they fiercely defend their territories and their feeding sources. Watching a full-blown hummer battle is quite a sight; these tiny birds really have a go at it. They do not hurt each other, but if the intruder does not fly away after an initial bluffing charge, occasionally one can see a feather or two fly.
This little member of the species however had nothing to fear. Either no other hummingbirds had discovered its feeding source – or it was replenishing spent energy after driving away all rivals.
