Great Egret

I'm not sure of the actual name for this bird. It was down by the river, and was very quiet and slow moving, as if trying to not be noticed. As I got too close to try to get a photo, it took flight. Later it was back, again walking very slowly, and quietly. It was a fun bird to watch. It had an amusing strut as if it was trying to "walk like an egyptian", but much slower than Steve Martin's strut. Does anyone know what kind of bird this is? I'm thinking it's a crane. I don't see many like this one in Wichita.
