Acts of kindness in the wild

Papa cardinal and a mourning dove share a moment. On this day, they share a cool pot together. The dove was there first. At first papa was on the green pot and then jumped up with the dove. Prior, papa was hunting insects for the fledglings, maybe he is taking a break, or maybe he just wanted the higher location for looking. No clue. But what I love is how since mama and papa cardinal have had their 3 babes, and are really working hard to care for them, the mourning doves have kicked it up a notch with kindness. It almost seems like they try to help. Here he is cutting slack allowing papa to invade his space. They have often stepped aside at the feeder and I have seen what appears to be help in guarding the nest and babes. Generally, they don't give the feeder up without a fight, so this is really quite sweet. I wonder what these two are thinking?
