(5) Area Code . Locations of waterfowl observations will be coded in 

 the "Area Code" column. This will eliminate the need for plotting waterfowl 



observations on base maps. Use letter codes as shown in Figure of the 



Final Report; use column 54 only (the right-hand column). 



(6) Species . Use four-letter abbreviations of common names as listed 



by Skaar (1975). If common names consists of one word, list first four letters 

 (e.g.. Pintail = PINT). If two words, list first two letters of each word 

 (e.g., Canada Goose = CAGO). If three or more words, list first letter of 

 first two words and first two letters of last word (e.g.. Ring-necked Duck = 

 RNDU; Blue-winged Teal = BUTE, Great Blue Heron = GBHE), etc.) Identify 

 birds to species if possible; if this cannot be done, indicate UNDU (=Unident. 

 Ducks); UNGE (="Unident. Geese"); UNKN (="Unknown") ; etc. Where several spe- 

 cies occupy a given water area, it may be necessary to use several rows to 

 record the data, or even several rows for one species. 



(7) Census . An X in this column indicates that all water birds occupying 

 the water area in question were recorded; this includes waterfowl, shorebird, 

 kingfishers, herons, etc. 



(8) Activity : List first two letters of word; for example: 

 FL - Flying CO = Courtship 



SW = Swimming MA = Mating 

 FE = Feeding NE = Nesting 

 ST = Standing PE = Perched
