Sound and vision

I received a pair of binoculars as a birthday present recently, and the kids and I have been using them to explore the surrounding country and notice birds. Just in time for summer. I also read more of What It’s Like to Be a Bird and was again reminded how crazy cool birds are and how much we still don’t know about them (like when irruptions happen), which makes me happy.

Here are some sound and vision-related facts abut birds that I think are super cool.
