L'Oiseau et ses sens

Birkhead's insights really made me wonder how he immersed himself in understanding bird senses. Was this a lifelong passion or a specific moment of inspiration?

The detailed descriptions of how birds find their way or communicate felt almost magical. I’m curious if others found themselves marveling at these natural wonderings.

The variety of birds studied was impressive, but I wonder what guided the selection—was it based on their uniqueness, accessibility, or something else?
