Flock of Robins

What a surprise one morning a few days ago when I awoke to see this out of my kitchen window. I didn't catch as many as I wanted to on photo as I wanted but this is what I was able to get. This is the view out of my side kitchen window ... What I saw was a huge magnificent flock of robins gathered around and flying about and on the ground finding their breakfast. Can you see the ones left in the picture? I think we are inadvertently feeding the robins because this, I've found, seems to be where the water from the sink seems to drain! I am trying to be a little more considerate of what I put down that drain. Seeing birds feeding there make you much more aware, that's for certain.
