Purpose is to provide a stable, long-term home for Crossbill research over a broad front: field observations, recordings, assortative mating and call type delineation by sound, range and DNA. Provide information to the scientific community on the validity of call types and potential full-species separations for flight call types, geographically isolated populations (old world versus new world) etc. One purpose would be to serve as arbiters of flight call determination via audiospectrographic analysis and machine learning/AI for this worldwide complex.
Whether it’s through loving birds and getting in the field to watch our feathered friends, the easiest and best way to be a part of this collaborative network is that whenever you’re the field and you hear crossbills, especially if you’re in Canada or somewhere across the Western Palearctic where recordings are scarce, is please grab a recording, whether with professional gear or phone, and upload it to Xeno Canto, BirdNet or ideally Macaulay Library! Macaulay Library has over 8300 crossbill recordings making it the most common species in the collection by almost 30%, and that is thanks to all of you!
We hope to get to the point where we can help fund summertime student research projects. And lastly, we implemented an ARU component of The Crossbill Project this past summer, and if you’re interested in helping in the future, please contact us as well.
