Judging from the shattered cover to my outdoor light, the dead bird, and feathers and blood over the pieces and the deck, I surmised that a gray colored bird of some kind (most likely a mockingbird) had flown into the cheap glass covering of my outdoor light fixture with enough force to shatter it. I feel kind of bad, because there used to be a mockingbird that sat on our chimney and made all these songs. But he was swooping and attacking the squirrels and mourning doves that sometimes got on the roof.
I guess he made one dive bomb too low.
But I need a new light fixture anyway.
