This folder contains maps showing distribution and abundance of Sula dactylatra (Blue-faced Booby) [or Masked Booby] based on at-sea observations from February 1963 through August 1965 for the Pacific Ocean Biological Survey Program. Distribution and abundance data are represented by symbols, numbers, and colors added to printed maps of the central Pacific Ocean. Each map shows data from one calendar month, with one map for each month of the year. No year information is shown on the maps, although an explanatory page in the folder says that the maps represent observational data from February 1963 through August 1965. Each map may therefore represent data collected during that month in one year or more than one year. There is one hand-colored map and two uncolored copies for each month of the year. Each symbol (square or circle) on the map represents one day's observations, with number of birds observed that day written inside the symbol. The map legends and explanatory sheet in the folder provide additional information on interpretation of the maps.
