Spot mapping is widely used in bird research, but the time required to compile species composite maps and the limited utility of paper maps are a drawback to its use. A Geographic Information System (GIS) was used to enter and analyze spot-mapping data. A new program (BIRDMAP) was written using the programming language of PC ARC/INFO to digitize data from field maps. Use of BIRDMAP greatly reduced the time required to produce species composite maps. Specific applications and benefits of using a GIS for analysis of spot-mapping data are presented.
