SGS-LTER Avian Road Counts (Breeding Bird Survey) in eastern Colorado, USA 1994-2002

The BBS is a large-scale survey of North American birds. It is a roadside survey, primarily covering the continental United States and southern Canada, although survey routes have recently been initiated in Alaska and northern Mexico. The BBS was started in 1966, and the over 3,500 routes are surveyed in June by experienced birders. Routes 305, Nunn and 901, Rockport are located in the area of the SGS research site. The primary objective of the BBS has been the estimation of population change for songbirds. However, the data have many potential uses, and investigators have used the data to address a variety of research and management objectives. In the USGS-BBS Home Page, reults from the BBS are summarized, and supplement the results with pictures of birds and other species information. Data from 1966 - 2002 also can be downloaded from the SGS-LTER website.
