Article summary

On the occasion of the 50th anniversary of Aves, this article reviews the evolution of the “opportunistic” observation database of the association. This database organizes data from daily bird records of hundreds of birdwatchers, collected outside survey programs conducted with a specific protocol. More than 1.8 million data have so been accumulated, first from monthly reports sent by the observers, then, since 2008, through specialized data portals, the most famous being “observations.be”. Part of the pre-1989 data are at this moment only available in the form of handwritten files, currently being digitized. The data transmitted through online data portals are not only more numerous (about 300,000 per year) than during the pre-portal period, but also different in many ways which are discussed in the article. Some potential uses of this database are also reviewed.
