Reproductive parameters in captive hand-reared black-bellied sandgrouse

Abstract 10.1002/zoo.20185.abs 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 […]

Artificial incubation of trumpeter swan eggs: Selected factors affecting hatchability

Abstract 10.1002/(SICI)1098-2361(1999)18:53.3.CO;2-# Eggs collected from captive trumpeter swans (Cygnus buccinator) in 1993 (n = 33) and 1994 (n = 42) were artificially incubated with careful monitoring to identify factors contributing to the low hatch success reported by the Ontario Trumpeter Swan Restoration Program. Fertility was > 80% in both years, whereas hatch success of fertile […]

Artificial incubation and hand-rearing of ‘Alala (Corvus hawaiiensis) eggs removed from the wild

Abstract 10.1002/zoo.1430130307.abs The wild ‘Alala (Corvus hawaiiensis) population has been declining for many years, and only a few pairs of birds are currently reproductively active on the island of Hawaii. A recovery program was initiated in 1993 which included removing eggs from wild nesting birds for artificial rearing and reintroduction. This paper describes the artificial […]

Captive breeding and reintroduction of the endangered masked bobwhite

Abstract 10.1002/zoo.1430100602.abs Efforts to restore the endangered masked bobwhite (Colinus virginianus ridgwayi) to its former range have required 1) habitat acquisition, restoration, and preservation; 2) captive propagation; and 3) reintroduction of captive-bred stock. In its role to recover the masked bobwhite, the Patuxent Wildlife Research Center (U.S. Fish and Wildlife Service) has refined captive breeding […]

Hand-rearing, growth, and development of the red bird of paradise (Paradisaea rubra) at the New York Zoological Park

Abstract 10.1002/zoo.1430100104.abs Growth and development of six hand-reared red bird of paradise chicks was documented at the New York Zoological Park from March 1988 to May 1989. A total of 16 eggs were laid, of which 10 were fertile. Clutches consisted of two eggs and the female left the next infrequently during incubation. Two chicks […]

Report on captive hatches of California condors (Gymnogyps californianus): 1983–1990

Abstract 10.1002/zoo.1430100108.abs The California condor (Gymnogyps californianus) recovery plan entails increasing the reproductive rate via replacement-clutch manipulation and artificial incubation of eggs. During the period from 1983 to 1990, 37 eggs have been artificially incubated; 32 of these were known to be fertile and 28 hatched (fertility: 86.5%; hatchability: 87.5%).

Hand-rearing Greater flamingos Phoenicopterus ruber roseus for translocation from WWT Slimbridge to Auckland Zoo

Twenty Greater flamingo Phoenicopterus ruber roseus eggs, originating from a flock held at the Wildfowl & Wetlands Trust, Slimbridge, UK, were hatched in incubators. The chicks were hand-reared in a pre-export isolation facility before being successfully translocated to Auckland Zoo, New Zealand, at 33–71 days of age. At Auckland Zoo the flamingos were held in […]

Captive-rearing of Gunnison sage-grouse from egg collection to adulthood to foster proactive conservation and recovery of a conservation-reliant species

Gunnison sage-grouse (Centrocercus minimus) are distributed across southwestern Colorado and southeastern Utah, United States. Their distribution has decreased over the past century and the species has been listed as threatened by the U.S. Fish and Wildlife Service. Reduced genetic diversity, small population size, and isolation may affect Gunnison sage-grouse population persistence. Population augmentation can be […]
