The birth and early development of a captive sifaka, Propithecus verreauxi coquereli.
We report here our observations on parturition and infant development up to five months in a captive sifaka, Propithecus verreauxi coquereli. Comparisons are made with other reports of Propithecus. In describing the acquisition of developmental landmarks, a distinction is made between the first sighting of a behavior pattern and its regular occurrence in the infant's repertoire. We describe the development of locomotor abilities, grooming, feeding, play, and social interactions. In general, maturation of Propithecus is slow relative to species of the genus Lemur.
