In the 2012 President's Budget Request, the National Biological Information Infrastructure (NBII) is terminated. As a result, all resources, databases, tools, and applications within this web site will be removed on January 15, 2012. For more information, please refer to the NBII Program Termination page.
Birds are valuable to humans as they provide aesthetic enjoyment as well as important
(seed dispersal, pollination, predation, scavenging, nutrient deposition, ecosystem engineering),
(food, recreation), and
(art, religion). Bird conservation has been a national priority in the United States since the early 1900s, when scientific evidence showed that humans could negatively impact the long-term sustainability of bird populations. Recent findings indicate that a third of North America's bird populations declined during the last half of the 20th century, so there is clearly a continued need for bird conservation at local, state, regional, national and continental scales.
Updated MAPS Demographic Estimates
The Institute for Bird Populations has recently updated the avian demographic estimates provided via the online NBII/MAPS Avian Demographics Query Interface. These regional estimates (number of adult individuals, productivity, annual survival rates) for over 150 species of landbirds are based on data collected during the period 1992-2006 at bird banding stations in North America as part of the Monitoring Avian Productivity and Survivorship (MAPS) Program.

The NBII Program is administered by the Biological Informatics Program of the U.S. Geological Survey
