DS2 was down on the patio opening up the umbrella when DH noticed this guy on the top. It had been sleeping in the folds. It wasn't really ready to wake up yet and it did wait a few minutes before flying off - - right to the deck, where it did a few figure eights around DH to express its annoyance before leaving. I'm glad I got a few pictures.
