Young Scarlet Ibis (Left and Center) Lack Their Parents' Vivid Plumage This Venezuelan bird city, by the author's estimate, had a population of about 10,000. Dark juvenile ibis quit nests and maintain bush-top positions until they can fly. Reddish feathers emerge only after the first molt. A complete color transformation requires about three years.
