Your DP is so strange. At first glance to me it looks like some guy is taking his black (or whichever colour the birds are) sunglasses and then it takes me 1-2 seconds to realize that it's some birds on a ledge. I have seen it countless times yet still make the same error.

Wow. I had never thought of that.
