Forget Angry Birds, I have hungry birds.

Normally, I fill my bird feeders once a week.  Lately, I have been filling them twice a week.  In the past, I would be suspicious of a squirrel raiding my feeders, but, I have seen as many as a dozen birds on the feeders at the same time.  Plus, the seed seems to go down at a uniform rate amongst all of the feeders. And, on days when I am home, I can observe the seed going down.

I guess the dry conditions have created a food shortage.
