BirdNet is the home to the collections of the Holliday Lab at the University of Missouri (https://hollidaylab.com/). Here we host CT, image, histology and other data collected as part of our NSF-sponsored research on the form, function, and evolution of birds, dinosaurs and other vertebrates. Research is sponsored by NSF IOS 1457319, NSF EAR 1636753, and University of Missouri. Our sibling site "Crocnet" (https://osf.io/jmpck/) hosts similar data collected for alligators and other crocodilans.
