The North American Breeding Bird Survey is our longest running continent-wide survey of breeding birds. Each year during the height of the avian breeding season (late May to early July), skilled birders collect bird population data along roadside BBS survey routes. Each survey route is 24.5 miles long with 50 stops situated 0.5-mile apart. At each stop, a 3-minute point count is conducted, and every bird seen or heard within a 0.25-mile radius is recorded. Routes are surveyed once each season, following the same roads and making the same stops each year.
Observers should be skilled in identifying the birds of the region by sight and sound (sorry, you can't use Merlin sound ID to find and ID the birds for you). The BBS is looking for volunteers to make at least a three-year commitment to surveying a route. Visit here for
more information.
