Hello and welcome.

This is the Science of Birds.

I am your host, Ivan Philipson.

The Science of Birds podcast is a lighthearted exploration of bird biology for lifelong learners.

In this episode, which is number 76, I'll be answering some interesting questions sent to me by my listeners.

Questions about birds, I mean.

Just to be clear, these aren't random,

interesting questions like, can pure reason lead us to understand the ultimate nature of reality?

Or, which is better, sharks or snakes? No, we're talking about birds today, of course. But in case you're still thinking about those

two questions, I'm not so sure about the ultimate nature of reality, but snakes for sure.

Snakes all the way. The questions in today's episode came from not just any old listeners, but

from my supporters on Patreon.

At the two higher tiers of support, one perk for my patrons is the chance to send me questions

for these Ask Me Anything episodes. So if you'd like to ask your own question for a future episode,

consider becoming a supporter of this show on Patreon.

All right. Let's jump right in.

Our first question comes from Jamie.

Here it is. Quote,

Why do some bird's eyes change color as they age?

For example, the osprey, my favorite bird.

End quote.

Excellent question, Jamie.
