Hummingbirds at the window

Here is our view of the little hummingbirds feeding at our living room window feeders. It is fun to watch them as they fight over ownership of the feeders. Occasionally they co operate for a few minutes and allow another to feed at the second feeder while the first continues to eat. We once even saw two females at separate stations of the same feeder. Looking at the pictures(especially close up) I see how badly I need to clean the glass...all those little drips from every time I refill the feeders sure show up with digital.
