bbs1980

bbs2000

The data consists of binary presence/absence matrices for 569 bird 
species across 49 US states for two time slices (1980 - 1985 and 2000 - 2005). 
Only species (identified by AOU number) recorded during both time periods are included. 
The data are taken from the North American Breeding Bird Survey dataset and from a 
version of the database downloaded in May 2009.
