They show up where there is water. We had one hanging around the drainage pond at the ranch. At 7100’ in the mountains east of Albuquerque. Probably no other body of water for 20 miles.
I have a little cabin at the Lake of the Ozarks back in a small cove. I have a Blue that lives in the cove and is on my dock or nearby during the course of the day as it goes in and out of the cove.
I also get occasionally a Green Heron, much shorter and normally not extending its neck except to feed. More colorful for certain.
