Reproductive parameters in captive hand-reared black-bellied sandgrouse.
Flock breeders of black-bellied sandgrouse originated from wild-laid eggs collected in west central Morocco in 2003 and 2004, were hatched, and hand-reared in captivity in the framework of a reinforcement population program. Three to five pairs of different ages were housed in an aviary. Egg-pulling procedure was used and eggs incubated artificially. Breeding parameters, hatchability, and posthatching mortality were recorded. The black-bellied sandgrouse showed a seasonal breeding pattern with a laying period extending from 7 to12 weeks. The clutch frequency varied from 3 to 7 clutches per female per season. The mean clutch size was 2.66+/-0.47 eggs, and the mean interclutch interval was 10+/-2.7 days. The average total egg production was 12+/-5.83 eggs per female varying with age from 8 to18 eggs per female. Egg hatchability of incubated eggs increased with age and varied from 37.5 to 72.2%. Chick mortality occurred only in the first week after hatching, averaging 60.5%. The obtained results showed that black-bellied sandgrouse can be successfully bred in captivity and opened the possibility of controlling, managing, and maximizing their production for the reinforcement of the local declining wild populations.
