Since some of you approached us if it would be allowed to use taxonomy data for training, I’d like to announce that this is indeed the case. Using a taxonomy e.g. to train hierarchical models will be allowed and you are free to use whatever resources you might find helpful. Please make sure that any information you intend to use for taxonomic training is publicly available.
Since we are using the eBird taxonomy (Clements list), take a look at this page: https://www.birds.cornell.edu/clementschecklist/download/
