Two captive pairs of Little Tinamou (Crypturellus soui) were studied to describe reproduction, development, and associated behaviors of this extremely cryptic forest dwelling species. Pairs were strongly territorial. Precopulatory courtship behaviors were performed by the female. Male tinamous showed strong nest attendance during incubation and sat without leaving the nest from day 14 until the eggs hatched. Nest abandonment and false abandonment occurred due to environmental stress, flushing by humans, eggs being laid in a poor location, and if clutch size was too large. Renewed reproductive efforts began shortly following loss of a previous clutch, with calling activity and inter-clutch duration being a minimum of 3 and 5 days, respectively.
