I spent the afternoon with friend Laura at Barr Lake State Park which I’d never visited, despite living in Colorado for 24 years. It’s embarrassing, really. Tons o’ birds hang out there and I didn’t know about the park until Laura asked if I’d ever been there.
We remedied the situation today and it was a glorious three hours. I took gobs of photos, some of which I’ve already deleted. Many, though, make me smile.
Throughout the afternoon, Laura wondered about the bump/horn on the pelicans’ bills. I finally took the time to pull out my little bird guide and then read this to Laura: Breeding adults also usually grown a flat fibrous plate in the middle of the upper mandible. The plate drops off after eggs have hatched.
Laura’s response: “But why? Why do they grow that?”
Well, I just did a little online research and still have no idea why breeding adults temporarily grow what appears to be enormous warts on their bills. However, that lack of knowledge in no way detracts from my gratitude for walking and talking with my friend on a beautiful, sunshine-y spring day in a bird wonderland.
