From what I gathered today, while being in the Chat room, eagles prefer cold weather to warm weather. They have been there done that with this type of weather. It is spring there, so the temperatures are just right for them. Not even freezing. The cottonwood is a strong tree and sways nicely in the wind. This birds are made to take care of themselves in what we might consider to be harsh weather. Most of the eagle population is in Alaska for heavens sake. Watch out for ..... oh never mind.
I, too, thought horrible things about the weather, but the eagle folks related to the reserve are laughing at all us wimpy folks. The eagles are fine. The parents have a 100% eaglet survival going. And if one doesn't make it for some reason, well, that's mother nature for you.
I encourage everyone to go to the site to check out the eagles. It's a chance of a life time to see them feed the eaglets and themselves etc.
