In recognition of the important role birds play in natural ecosystems and in our culture, we join World Migratory Bird Day (second Saturday in May for U.S. and Canada – May 12, 2018) and the Year of the Bird (2018) in bringing attention to birds and their conservation. Data and information on migratory and non-migratory native birds have been used in research, management and conservation of wild birds in the United States for over a century.
Here we highlight some examples of datasets resulting from federally supported long-term surveys of wild birds in the United States:
(Year in parentheses represents the last year of data available online from data collected in a survey. Recent data after that year may be available from the point of contact for each survey.)
• Mid-winter Waterfowl Survey (2016)
In addition, the following general biodiversity (all species) resources provide access to bird occurrence data from multiple data sources:
• Biodiversity Information Serving Our Nation (BISON) – provides access to species occurrence data for animals, plants, fungi and other taxonomic groups in the United States. Currently, BISON contains over 300 million bird occurrence records from data sources such as eBird, North American Bird Banding Program – Bird Banding Lab, North American Breeding Bird Atlas (BBA) Explorer, North American Breeding Bird Survey (BBS), and many other projects and natural history museums.
• USA National Phenology Network (NPN) – provides access to data about the recurring life cycle stages (phenology) of plants and animals. For migratory birds, examples of phenology data include first arrival date and date last seen. Also includes data on hummingbird nectar plant phenology.
