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 incubation and hand-rearing techniques. Eleven eggs were removed from three nesting pairs; eight were fertile, and seven hatched and were hand-reared (fertility, 72.7%; hatchability, 87.5%; survivability, 100%). Eggs were incubated in a forced-air incubator at 99.5°F (dry bulb), 80.0–86.0°F (wet bulb), and hatched under still-air conditions at 99.0°F (dry bulb) and 88.0–90°F (wet bulb). Hatched chicks were hand-fed a diet of fruit, insects, and mouse pups. © 1994 Wiley-Liss, Inc.
