The main publication resulting from WBBS is the BTO's BirdTrends report, in which the survey's long-term trends are put into context alongside other monitoring of population levels and measures of breeding productivity and annual survival rates. The overall picture for each species is discussed using the recent scientific literature. BirdTrends is updated annually to take account of each year's new data and publications.
A series of BTO research reports details the planning and development of the WBBS and aspects of its results, for birds and for mammals. In addition, there are some peer-reviewed publications that have used WBBS data. Some key references are listed below, in date order:
