The female constructs her nest largely of plant down bound together with spider webs and saliva. The outside of the nest is camouflaged with bits of moss and lichen, so that it is virtually indistinguishable from the branch to which it is attached. The mother incubates the eggs, without help from the male, for 15 to 19 days, depending on the species. Newly hatched hummingbirds are almost completely featherless, and are remarkably ugly, but are more hardy than their size would indicate. The mother feeds them for about 25 days, by which time they leave the nest and begin to fend for themselves.
Most hummingbirds raise two broods each breeding season.
