Migrant waders at Aldabra, September 1967—March 1968
Observations of palaearctic waders during the first three phases of the Royal Society Expedition to Aldabra, between 1 September 1967 and 14 March 1968 are listed and compared with those from other places in the area. Seventeen species are included in the check list, of which four are considered vag...
