  1. Artificially incubate and hand-rear parrots in captivity

    A replicated, controlled study at a rehabilitation centre in southern Brazil in 1997-9 (Seixas & Mourao 2003) found that hand-reared blue-fronted amazons Amazona aestiva grew for longer than wild birds (with an average growth period of 64 days for 124 captive-reared birds vs. 56 days for 86 wild nestlings). This meant that fledging weights of captive-reared birds were significantly higher than wild birds (average weights of 401.g for 34 captive males and 362 g to 28 females vs. 364 g for nine wild males and 343 g for 12 wild females). Birds were initially fed on a mix of mashed fruit, vegetables, corn flour and puppy food three times per day, changing to fruit, vegetables, seeds and grain as they grew.
