luv2bird:See those funky holes that look like ears? OMG the bird emits weird gaseous sounds every few minutes out of those holes that I thought were ears but they're not ears. The purpose and function are gross ... nevermind.
I've looked in lots of articles online and see nothing as to what purpose and function these holes serve ?
