Rehabilitation of injured and treated birds
A small study in mixed croplands, forests and pastures in Louisiana, USA (Hamilton et al. 1988), found that, of eight red-tailed hawks Buteo jamaicensis and one red-shouldered hawk B. lineatus rehabilitated and released over six occasions in 1985-6, one red-tailed hawk died 17 days after release, the red-shouldered hawk was shot and had to be rehabilitated again and four other red-tailed hawks survived for more than two weeks after release. This implies that these four releases were successful as starvation normally occurs within two to three weeks if hawks do not feed. The remaining three red-tailed hawks could not be successfully tracked. The birds had been admitted to a rehabilitation centre for a range of reasons, from confiscation by officials to gunshot wounds and had been in the centre from a few weeks to over a year.
