The crazy titmice are trying to steal Poke's fur to make nests. They do this over and over again, and sometimes Poke doesn't even realize it! Poke is an 18-year-old, fat, mean-spirited cat. One of our granddaughters calls him the "hell cat" because we've always called him the "Cat from Hell". He is like a huge rag mop, who mostly looks sort of dead.
This is looking east from our patio door out toward our back yard...as you can see from the bird feeders, we really encourage the birds.
BTW, we have had humming birds for the best part of a week.
