I saw a crane this morning

As I was running past a fishing pond south of 106th South, a crane skimmed over the water and then as it neared me, it rose to a higher height over the water. It was a gray color, and I'm guessing it was a Sandhill crane. I say this only because I found a picture via Google of a Sandhill crane, and the bird was a gray color. I passed the pond on my way back but didn't see the crane. I don't remember if the bird I saw had the red on its head, as shown in the following picture from Google.
