APPENDIX B 



LISTING OF COLONY NESTING DATA, 1900-1977 



The purpose of this supplement is to provide the reader with ready access 

 to detailed breeding data on all colonial waterbirds from southern Maine to 

 Virginia for the period 1900-1977. These data have already been summarized 

 and are presented, by State and species, in tabular form in Section III of 

 this report. 



All information concerning nesting numbers at specified location s in each 

 of the 10 northeastern States is presented. References to State or regional 

 totals are not recorded here, but are integrated into Section III. 



DATA SOURCES 



Both published and unpublished reports of breeding numbers were extracted 

 from a number of sources. All major ornithological periodicals were carefully 

 reviewed, especially the field notes sections (Table Bl). In most cases, all 

 issues in the journal series were available. Museum, research center, and 

 national wildlife refuge files provided a second major source of information 

 (Table B2). Also, data were requested from each of the State's Audubon socie- 

 ties. In most cases, this information was already available from other 

 sources. Lastly, a significant amount of data were obtained from unpublished 

 field notes and records of a number of professional and amateur ornithologists 

 (Table 82). 



Concerted efforts were made to contact as many active ornithologists and 

 waterbird banders as possible in an attempt to collect all nesting records. 

 In some cases, the data were not made available; however, the following com- 

 pilation represents the vast majority of waterbird nesting data. 



A bibliography of all data sources is included (Appendix C). The major- 

 ity of the literature survey was completed by December 1975, but important 

 additional journal references from 1976 and 1977 are also listed. 



DATA ORGANIZATION 



The data are organized by States. All data were recorded on computer 

 cards. Because of the nature of the data and the computer storage systems 

 used, four record types are included: 1) colony location, 2) 1977 field data, 

 3) 1976 field data, and 4) historical (1900-1975) data. 



The information for each record type is presented on microfiche at the 

 end of this report. Data entries are explained below: 



COLONY LOCATION DATA 



All colony locations, both present and past, are listed. In most cases, 

 U.S.G.S. map names are used. If no official name was available, the colony 

 was named after a major geographical feature (water body, etc.) nearby. 

 Location is given by latitude and longitude, judged to the nearest degree. 

 The "map ID" refers to the code number on the approximate U.S.G.S. 1:250,000 

 scale map (these code numbers are now superceded by a map name). Ownership is 

 listed but more detailed information is given in the atlas. The six-digit
