Redbilled Hornbill
A pair of Redbilled Hornbills preparing their nest in a hollow of a dead tree. When the female is ready to lay her eggs, the male seals the entrance nearly shut with mud, leaving only a small hole through which he brings her food. This continues during incubation (24 days). She does not leave the nest until the nestlings are half grown, at which time she reseals the entrance, except for the feeding hole. The total fledgling time is 45 days). [Masai Mara, Kenya]
