At first I thought I had found a stray piece of packing styrofoam littering my patio. But just as I was about to grab it to throw it away, I realized that it was not styrofoam at all. It was a hatched bird’s egg. I don’t know what bird this belongs to, but I have a hunch it belongs to the chubby birds fighting over the bird feeder. The second image is the egg with my thumb for a size comparison. Going to have to find me a Peterson’s Field Guide to see if I can match the bird feeder pigs to the egg. Will let you know what I find out.
