Week old robins

Robins built a nest in a fern hanging on the neighbor's front porch. Three chicks hatched a week ago, and within another week they will grow to be as large as their parents and will fledge the nest.

On these chicks downy feathers have been almost completely replaced by juvenile feathers. Feathers do not grow on all parts of the body, instead growing in defined feather tracts.  Feathers overlap bare spaces on the bird, giving the adult bird the look of being completely feathered.
