After seeing very few hummingbirds in the spring, they are now at our feeders in huge numbers, plumping up for the journey south. It has been so much fun watching them. At one feeder, it seems two adult males are sharing and running everyone else off. They spar with each other, but generally let each other drink. Everyone else has to work a bit harder to get to the nectar. It is an interesting dynamic. Sometimes, it seems aggressive. Other times, it seems more like play. Only they know.
