  1. Artificially incubate and hand-rear raptors in captivity

    A replicated study in a breeding centre in New York, USA, in spring 1970 (Snelling 1972) found that artificially incubated American kestrels Falco sparverius eggs were more likely to hatch when incubated at 38.5oC (100% of 11 eggs hatching), than at 36oC (34% of 13) or 40oC (25% of 12). Whether the eggs were cooled to 21oC twice daily or not did not affect hatching success (61% of 18 cooled eggs hatching vs. 44% of 18 non-cooled eggs). Sixteen of the 19 hatched chicks were raised to fledging on a diet of minced meat. Eggs had been naturally incubated for 2-26 days before being taken from the wild.
