Cranial kinesis in a hyacinth macaw, the largest flying parrot

Demonstration of cranial kinesis in a hyacinth macaw (Anodorhynchus hyacinthinus), the largest flying parrot species. WitmerLab grad student James Nassif dissected this specimen (OUVC 10883), and then it was skeletonized in our dermestid beetle colony.. Immediately after it came out of the disinfecting hydrogen-peroxide/ammonia bath, the intracranial joints were still mobile, so I took the opportunity to film a quick video before it dried. This project was funded by our National Science Foundation (NSF) grant to study the evolution of avian kinesis. This macaw was not sacrificed for our research but rather was a natural casualty of a captive-bred bird that we were able to obtain for our studies.
