Rufous Hornero reproduction
Two to four white eggs are laid, mostly between August and December. Both parents incubate for about 14 to 18 days and feed the chicks, which leave after roughly 23 to 26 days. The young often stay on their parents' territory for several months.
Males and females look alike in plumage and size. In the pair's duet the two sexes sing different parts at different tempos, so a practised listener can tell them apart by ear.
