Spent a couple of days last week in Yellowstone National Park - The Bison were handling the colder better than I was. One morning it hit -31F.
BTW - that river in the first photo would be frozen solid if it wasn't being heated by all of the geothermal activity in the park.

This image is a repost from last year, just for the purpose of pulling the 200-500 thread closer to the top again. Great lens! I love it.
Anyway, in one of this year’s (2020) loon images, I noticed that one of the two sibling chicks (that was under the parent’s wing), was so low on the parent’s back, that *its bottom had to be in the water*.
The underwing area is “warm as toast” (as they say). Birds run a higher body temperature than we do..... about 105 fahrenheit. And the babies are out and about in cold (or at least cool) spring rain. With only down feathers, chicks are subject to hypothermia, but not with that underwing area to quickly escape the cold. When a baby approaches the side/end of the parent, the parent lifts the wing slightly, offering entrance. They can climb up and get under those warm wings whenever they choose. And the wings are lined with down feathers.

Finally had a little luck in capturing some Pronghorn - They are so skittish and so fast that my only previous photos were shots of their rear ends running away from me...
