I looked at the direction where the boy was gesturing and saw a pigeon nesting on the cradle of C in the P-H-A-R-M-A-C-Y sign. If you look closely, you can see two eggs sitting precariously on the edge of the nest. According to Wikipedia, pigeons lay just two eggs per season so these two eggs are probably the only eggs in the nest.
If you love nature photos, you should check out Brookville Daily Photo by Abe Lincoln. He has some of the most beautiful nature photos I have ever seen. And most of them are taken in his backyard.
So what is in your backyard?
