Too cold to fight

It has been so cold in the mornings. Yesterday, I saw one of "our" hummingbirds sitting at the feeder with feathers out. It looked like a fuzzy ornament instead of a sleek, little, glittery bird. This morning, I saw two hummers sharing the Hummerfest feeder. I've only seen that happen once before. At that time, both birdies were surprised to see the other at a feeding station. This time, the first bird allowed the second to land and drink. Too cold to fight?

Speaking of fight, there is now a hummingbird drone for gathering intel for military use. It's slightly larger than a real bird, but can only fly for 8 minutes. DOH? How is that useful? Apparently, the current bird drones resemble pigeons or was it doves?
