BRIEF NOTES ON THE BIRDS OF SAN AMBROSIO AND SAN FELIX ISLANDS, CHILE

San Ambrosio Island, together with San Felix 17 miles to the NNW, and the smaller González Islet form the San Felix Group situated on Lat. 26° 20'S and Long. 80° W. These islands, like all the others scattered off the Chilean coast, are outcrops of volcanic origin which emerge from depths as great as 10,000–14,000 feet below sea level. They lie 500 miles west of the port of Chañaral and about the same distance due north of Juan Fernandez (Robinson Crusoe) Island. As they lack fresh water and lie off the regular navigation routes, civilization has passed them by and, except for occasional visits by lobster fishermen, has left them uninhabited.     

THE BIRDS OF THE COCOS-KEELING ISLANDS (INDIAN OCEAN)

The birds of the Cocos-Keeling Islands, in the Indian Ocean, are discussed in the light of specimens and data collected during a stay of eleven months in 1941. Seventeen species were found to be breeding. One of these was an indigenous land bird, four were land birds known to have been introduced, and the remainder were sea birds mostly confined to North Keeling. During this period examples of seventeen species of strays or visitors were taken, of which ten probably occur regularly though in small numbers, while the other seven are true vagrants. Eight of these birds have not so far been recorded from Christmas Island.
Eleven birds listed from the islands by previous visitors were not present in 1941. Two of these were introduced but have failed to maintain themselves, and one, Egrctta garzetta nigripes , seems to be an occasional vagrant. The remaining eight records are all unsatisfactory.     

BIRDS ON GRENADA

Resident and transient birds seen on Grenada in 1971 are listed. Leptotila wellsi still persists. Apus apus is new for the West Indies. Nearly half the resident land birds are regular in both lowlands and highlands.
