The cranes were flying in and landing on the Rio Grande in bunches. Click on photos to enlarge them.
These are not technically Fire Rainbows (very rare) because we are below 55º north latitude, and the sun was much lower than 58º above the horizon as the sun was setting. However, the clouds were cirrus, and they obviously had ice crystals acting like prisms refracting sunlight and creating a firey rainbow effect. They are probably run-of-the-mill rainbow clouds.
