We watched a big group of Sandhills kettling yesterday. I went inside to get my wife, she'd never seen it before. They kettled for 5 minutes or so until they found the current they wanted, then dropped into the V formation and headed your way. That coupled with the Mesquite trees starting to bud tells us Spring us on the way down here.
The first time I ever saw sandhill cranes I was ice fishing with my wife and another friend. It was about 28 years ago. A late winter day, sunny, about 50+ degrees, with 3-4' of fog sitting on top of the ice. You could just see people's heads and shoulders if they stood up. Off at the southern edge of that lake, there was a large grassy field, all brown from the winter. You could see the heat shimmering up from it. That's when I heard that unique sound that sandhills make. I'd never heard it before. I started looking around and here comes this line of about 50 of them across the lake, only a couple hundred feet up. When they got over that grassy field, they just put their wings out and started circling and circling, never flapping, the whole bunch of them just rising up on that heat. They must have been a couple thousand feet up before they took off again to the north. Outstanding! That was one of the best days ice fishing I ever had and I didn't catch one fish.
It was so warm we were just in sweaters, no jackets. But the whole time we were out there, you could hear water trickling very loudly. If you drilled a hole, it wasn't long before water was swirling down it like a drain, bringing all the dirt and dust off the top of the ice. By the time we were getting ready to get off the ice, we got back to shore, and what had been a 6" gap of water when we came on was now 3 feet!
We looked around, and someone had put a picnic table in the water as a bridge a couple hundred yards down, and that's how we got off the ice. Would have been knee deep if not for that table.
Went home and looked up the sandhill cranes. Very nice. Now they are every where. Early and late winter migrations south and north, but they now nest here in summer as well. I actually heard them in every month this year. They never went too far south.
