Artificially incubate and hand-rear songbirds in captivity
A small study at a captive-breeding centre in New York, USA (Cade 1992), found that eight loggerhead shrike Lanius ludovicianus chicks removed from the wild and hand-reared from 8-9 days old survived. Two bred (see ‘Use captive breeding to increase or maintain populations’) and two of their chicks were removed, hand-reared and released. Both survived for several weeks until they disappeared.
Use captive breeding to increase or maintain populations of songbirds
A small study in New York, USA (Cade 1992), reported that a pair of wild-caught loggerhead shrikes Lanius ludovicianus (from a total of eight birds caught and hand-reared from the age of 8-9 days in 1970) formed a pair-bond and laid seven eggs, all of which hatched. However, none of the young survived. A replacement clutch of three eggs was laid, of which two survived and were hand-reared (discussed in ‘Artificially incubate and hand-rear birds in captivity’).
