North American Breeding Bird Survey

Route Abundance, Trend Analysis, and Land Cover Form


This part of the Home Page provides data and results from individual survey routes. You select a route, and all species information will be summarized and displayed, along with links to other information about the species found on the BBS route. This version of the page also provides links to land cover data for the Continental United States.
BBS routes are named for the town nearest the start of the survey route. In this list, we list routes by state/province, route number, and the route name. Survey routes in National Parks are listed at the bottom.
Want more information about the route locations? Please access the BBS route location maps available on the National Atlas of the United States ® (no provinces yet, sorry). available on the BBS operations web site.

Caution! No species is found on every route, and some routes have data of insufficient quality to estimate change. Consequently, some analyses will provide empty graphs, and "NaN" errors indicating insufficient information.
