A Summary of Bird Record Information by Latilong 



The following maps use the latilong system to summarize the information stored in the 

 Montana Bird Distribution Database in two different ways. Figure 2 shows the total number of 

 records of all species entered for each quarter latilong (QLL) for the period 1991 through 1995. 

 Figure 3 shows the relative diversity of bird species with two different numbers: 1) the center 

 number indicates the total number of species ever reported for that latilong; and 2) the QLL 

 number shows the total number of species recorded in each QLL for the period 1 99 1 - 1 995 . Both 

 maps reflect where our contributors are birdwatching.
