The EBBA2 project was developed step by step with regard to funding. Many contributions were provided as in-kind funding by EBCC partner organisations. European project coordination was also partly funded by the organisations involved, but was supported to a larger extent by external funding from charitable foundations, in particular the MAVA Foundation, as well as governmental bodies, ornithological societies and private donors. A species sponsorship scheme on the EBBA2 website allowed societies and individuals to support the project with smaller contributions. Some of the artists providing illustrations also helped to raise funds for EBBA2 by selling their artwork and sharing their income with EBCC.
