Technical Announcements. Employees in the News. Emergency Management. Survey Manual. Each year thousands of citizen scientists skilled in avian identification collect data on BBS routes throughout North America allowing us to better understand bird population changes and manage them. Participate in the Survey - Each spring over skilled amateur birders and professional biologists volunteer to participate in the North American BBS.
We are always looking for highly skilled birders to join the team. Get Raw Data - Search and download raw data results. This strategic plan was developed in collaboration with key partners and stakeholders and charts the ambitious course for the BBS over the next decade — Using this plan as a guide, the BBS program will set out to improve the breadth and depth of standardized data collection and analytical products; ensure its products are widely used and recognized as the authoritative source for long-term population change information for most birds; and secure adequate resources, internally and through partnerships, to realize the expanded vision of the BBS intended to support avian management needs through Geological Survey, Canadian Wildlife Service, Mexican National Commission for the Knowledge and Use of Biodiversity and other possible collaborators providing a road map and starting points for accomplishing the three goals and eight strategic objectives of the BBS Strategic Plan over the next decade.
The action plan is a living document, subject to annual review and updates as tasks are accomplished and priorities change through time. Public domain. The website provides geographic displays and quantitative information on population trend interval-specific yearly percentage changes and annual indices of abundance for each species at several geographic scales, including survey-wide, states and Provinces, Bird Conservation Regions physiographic strata , and for individual survey routes in the United States.
Custom analyses of population change allow of analysis of change for any combination of years over which the survey was conducted. Along with maps, images, song and call recordings, and life history information are provided for species encountered along BBS and CBC surveys. We also include a quiz in which users get to test their knowledge of wintering and breeding distributions of North American Birds.
Ecological indicators of climate change are needed to measure concurrent changes in ecological systems, inform management decisions, and forecast the consequences of climate change. We seek to develop robust bird-based, climate-change indicators using North American Breeding Bird Survey data. The North American Breeding Bird Survey program BBS provides critical science-based population data for more than bird species to improve our understanding of how these federally entrusted species respond to environmental variability and ecosystem change.
It is relatively easy to construct complex hierarchical models for analysis of the North American Breeding Bird Survey BBS , but deciding which model best describes population change is difficult. We are developing methods for model selection for BBS and other important survey data sets, and using them to refine our estimates of population change from this important survey.
Designing and analyzing large-scale animal surveys is an important focus of our research. Although we conduct research into analysis methods for many surveys, the primary focus of this project is to conduct analyses and develop web-based summaries of data from the North American Breeding Bird Survey BBS. The BBS is a scientifically rigorous population count performed by a highly skilled, largely volunteer work force of nearly 2, observers.
This strategic plan was developed in collaboration with key partners and stakeholders and charts the ambitious course for the BBS Management interest in North American birds has increasingly focused on species that breed in Alaska, USA, and Canada, where habitats are changing rapidly in response to climatic and anthropogenic factors.
We used a series of hierarchical models to estimate rates of population change in 2 forested Bird Conservation Regions BCRs in Alaska based The North American Breeding Bird Survey BBS was established in in response to a lack of quantitative data on changes in the populations of many bird species at a continental scale, especially songbirds. Atlas data are proven to be among the most important tools for conservation and land management in the state. They provide critical information on where threatened and endangered species are breeding, which is invaluable for reviewing the impacts of proposed development projects like solar and wind farms.
The distributional and change data are critical for determining which species are of conservation concern e. This Pileated Woodpecker graphic will serve as the visual identity for the project, which is slated to begin in and continue through It was created by Evan Lipton , a young birder from Massachusetts. Congratulations Evan! In the early s, New York was one of the first states to undertake an Atlas project, mapping the breeding distribution of its birds. BBA Database - See species lists and distribution maps from the 1st Atlas and 2nd Atlas and see how the distribution of each species changed between the first two Atlases.
The first Atlas took place from to , the second from to The third Atlas will continue to improve our understanding of changes in the distribution of breeding birds in the state and provide the basis for more informed conservation and management of birds and their habitats. In the first Atlas, over 4, volunteers submitted more than , observations of species and three hybrids.
