NOTES ON THE BIRDS OF ANNOBON AND OTHER ISLANDS IN THE GULF OF GUINEA

Summary 1. A systematic list of the birds of Annobon Island in the Gulf of Guinea is presented with field notes obtained on a recent expedition, and the records are compared with those of previous ornithological visits. 2. The land avifauna of Annobon has altered markedly in the last five or six decades. That the resident land-birds provide severe competition for newly arrived immigrants is offered as the most plausible reason for the paucity of land-birds species on the island. 3. Brief ornithological notes from Sao Tom and Fernando Po are given as addenda to recent papers on the respective avifaunas.
