Ghana has lost 90–99 per cent of its African Grey Parrot (Psittacus erithacus) population in the past two decades, according to a study recently published by a team of researchers from Ghana and the United Kingdom.
The population decline of Grey Parrot, a heavily traded cagebird species, is evidenced by the near-total loss of the major roosts known in 1992. Further evidence indicates an almost a tenfold reduction in bird encounter rates observed in the 1990s compared to 2014, as well as the perceptions of 96 per cent of the almost a thousand residents that were interviewed during the study.
