How to Use Maps And Tables 



A few minutes taken to carefully read this 

 section should make your use of these maps and 

 tables much easier. Each Colony in this report is 

 included on one of 1 1 U.S. Geological Survey 

 maps which cover the California coast. An index 

 to these maps appears on the facing page. They 

 are numbered under a U.S. Fish and Wildlife 

 Service system covering the entire United States. 

 The first three digits of the six-digit catalog 

 number for each colony is the map number. All 

 data in the following maps and tables are organ- 

 ized into eleven sections corresponding to these 

 maps. 



Once you have determined which of these 

 eleven maps covers your area of interest, turn 

 to that section. Heading each section is a map of 

 that area showing the locations of all colonies 

 within that area. The numbers that appear here 

 (00 1, 002, 003, and so on) are the colony identi- 

 fiers, each specific for a colony area within that 

 map. These are the last three digits of the six- 

 digit catalog number. Note that these numbers 

 are not sequential along the coast. Many new 



colonies have been identified since catalog num- 

 bers were initially assigned by Varoujean, (1979). 

 We have retained these initial numbers and added 

 new colony numbers as necessary. 



A sample colony listing is given below. Note 

 that the populations are given in number of breed- 

 ing birds and not pairs. The reference (l, 2, etc.) 

 at the end of each data line corresponds to the 

 proper citation, page 341 , from which we obtained 

 the information. If further detail is needed about 

 a site, these sources should be consulted. For 

 information on the archiving of our U.S. Fish and 

 Wildlife Service field notes and photographs see 

 appendix A, page 35 1. 



Since there are many landforms with similiar 

 or identical names along the coast, such as "Bird 

 Rocks", "White Rocks", or "Castle Rocks", the 

 catalog number is important in distinguishing 

 sites. Therefore we list it after mentioning a site 

 in the text. If you know the name but not the 

 catalog number of a site you are interested in, 

 check appendix C. It lists all colony areas alpha- 

 betically and their catalog numbers.
