Activity 1. I had read recently of how roadrunners drop their body temperature at night and then the next day will spend time in the sun to warm up. After having read that information, I was able to witness a roadrunner sunning itself, standing on a rock with its back to the sun and wings slightly spread apart. Exciting that I already had the information before seeing the behavior.
Activity 2. I have the pleasure of attracting Ravens to my feeding area. I don't use standard feeders, just throw food on the ground. Ravens will stuff as much food as they can into their craw and beak, and then fly off to cache it in another location. Then the ravens will return for more food, and basically repeat the process. Also the Woodhouse Scrub Jays are similar in picking up food and flying off to cache it, as well as using their beak to open seeds on tree limbs. The Juniper Titmouse I also have observed uses its beak to hammer open sunflower seeds on the tree limbs.
