Why - I do not understand it!

One of my pictures (see left) is getting more views than any of my others. Why? I personally do not think it is a good picture. I used spot metering and it has blown out the background quite a lot. Such an effect is impossible to correct in photoshop - or indeed any other photo manipulation suite. I wonder if people are intrigued when they see the thumbnail and think they are going to see a real eagle instead of a sculpture? perhaps that is it. Can someone explain?
