The hummingbird Amazilia lactea (Lesson, 1832) built a nest in São Paulo, Brazil, in the spring (Oct) and added lichens during incubation. The female incubated over 70 per cent of the day, 1-56 min per visit, and brooded two small young somewhat less; brooding stopped by about 10 days of age, as did night brooding. Lack of night brooding for large young hummingbirds may reflect lack of space in a small nest. Young stayed in the nest 19 days. Feedings were widely spaced, and presence of possible predators caused alarm.
