The Pacific Ocean Biological Survey Program (POBSP) was initiated in 1962 when the Smithsonian Institution entered into a grant agreement with the Department of Defense. From January 1963 through June 1969 Smithsonian Institution employees undertook biological surveys in an area of the Pacific Ocean spanning the equator and extending from latitude 30 degrees north to 10 degrees south and from longitude 150 degrees east to 180 degrees west, an area dotted with clusters of islands and atolls. The major goals of the program were to learn what plants and animals occurred on the islands, the seasonal variations in their numbers and reproductive activities, and the distribution and population of the pelagic birds of that area. Emphasis was placed on the banding of birds in an effort to determine migration, distribution, and abundance of pelagic sea birds. During the six and a half years of field work 1,800,000 birds were banded; approximately 150,000 observations of pelagic birds at sea were made; and biological surveys of varying intensity were made on several islands.The present folder includes various annotated lists of observed cats and birds from Enderbury, by several members of the POBSP, including Sibley and Huber. The observations were made between 1963 and 1966, and a note dated from April 1966 states that "previous SIC trips have exterminated all mammals from the island'
