Our next door neighbors must love birds. They have about 5 feeders and a birdbath in their yard. In addition, one of them is always throwing bread out the window. The thing is, it just attracts pigeons. And they seem to get their food from next door...and then come to my window to hang out and sleep it off. And you know what pigeons do after they eat? Yeah, thats right ... they poop. So if they are hanging out on my ledge, what else do you think they are doing????
