How do birds hear us and their own songs?

In the spring we enjoy bird songs. How do birds hear us and themselves? At present we know surprisingly little about it. The bird ear has some similarity to the mammalian ear in neuronal organization but it has significant differences in structure. I present a brief account of how their ear possibly works, starting from describing how it is organized and how it differs from ours. Based on the structure of their ear, I describe a couple of attempts to come up with possible modes of motion in their inner ear.
