These three little guys were at my bird feeder this last week. Actually there were four little guys but you can only see a smidgen of #4 (behind the feeder on the bottom). This is not the first time this feeder had to put the "No Vacancy" sign out a time.
Want a photo tip? When I was starting to take this picture, I was a bit to the left of where I ended up. I moved to the right to take the photo. Do you know why? It was because that light brown streak at the bottom left of the photo was directly behind the feeder. That is a distracting element. By moving it out from behind the feeder it competes less for attention and draws more attention to the feeder. Always remember to consider your background when photographing. By the way, that light brown streak is actually an out of focus tree branch.
