Summary. During the latter half of September observations were made at various points on the coast of southwest Portugal. A great many migrants were seen, especially close to Cape St. Vincent, belonging to species that winter only south of the Sahara. Bird‐catchers were in evidence on the south coast, but not on the west. Evidence was obtained that migrants are fewest with east winds Most of the birds seen must have been travelling in a southwesterly direction for a long way and it is necessary for their survival that they should change course on reaching the shores of the Atlantic. Any that did not do so might find a temporary refuge on the Canary Islands, but the list of regular passage‐migrants there is very different from that of the birds seen commonly near Cape St. Vincent
