This dataset is the result of the digitization project "Aves Birds observation records anterior to 1990".
It provides ornithological data gathered by Aves between 1960 and 1990.
Since the early sixties, Aves, the bird study and protection society in French-speaking Belgium, now part of Natagora asbl, is collecting bird observation data in Belgium (almost exclusively in Wallonia and Brussels regions). Bird observation data in Aves collection are essentially generatedby "broad-scale surveys" in the sense of (Kelling, 2008) : data are collected mostly by volunteers, outside a strict experimental hypothesis-testing framework.
