This project is funded by ONR (Office of Navy Research) and the overall goal of this project is to study the hearing in auks. This project is done in collaboration with Aran Mooney from Woods Hole Oceanographic Institution.
We have measured the hearing of puffins at Tjörnes and also had sound recorders inside the puffin burrows to record the sounds of puffins themselves. The next step is to measure hearing of guillemots.
As part of this project, we also have captive guillemots at the Marine Research Center in Kerteminde, Denmark. Underwater sounds have been played back to the captive guillemots and we looked at their behavioural reactions.
