I have never seen them in a flock (or even a pair). Up here they are solitary, hanging around the dock or in the shallows. Thanks for sharing the pics.
Nice Pics, Were seeing quite a few more of them in Mn the last few years and I have a few that frequent my food plots, they are fun to watch and you can here them from quite a distance.
Those are Sandhill Cranes, that's the most I've seen in one flock around here although I see them this time of year and in the spring heading back north. On the news, there is a bunch of Whooping cranes going through here, that was yesterday also, just a little east of here, sure would have liked to have seen them, led by an Ultra-Lite on their way to Fl. for the winter.
