Volunteers drive the North American Breeding Bird Survey

Ziolkowski D, Pardieck KL

Jointly coordinated by the U.S. Geological Survey and the Canadian Wildlife Service, the North

American Breeding Bird Survey is the primary source of long-term, large-scale population data

for over 400 of North America's breeding bird species. At a cost of roughly $900 per species,

the program is regarded as a model for efficient large scale monitoring efforts. The success of

the BBS stems from three major components: a scientifically rigorous sampling design, a

straight forward field protocol, and an extensive volunteer participant base. Here we combine

the results of two BBS participant surveys with queries from the four-million record BBS

database to: (1) develop a profile of BBS volunteers; (2) examine BBS participant

demographics; and (3) examine the relationship between BBS management activities and long

term participation trends. More than 8,600 individuals have participated in the BBS in its 40

year existence, with approximately 2,000 volunteering annually since the 1990s. Volunteer

retention is high with 75% of new recruits returning the following year and remaining with the

program, on average, for 8 years. Despite the program's success in attracting highly motivated

and well trained volunteers, BBS volunteer trends exhibit a number of gains and plateaus which

are further discussed.
