what's on my head?

A bird just landed on my head. At first I thought it was a really huge fly. But then I saw it. A tiny chickadee, it hopped from the twigs on the chandelier to the branch that the pots and pans hang on to the surfboards on the ceiling, trying to get away from me as I attemped to capture it with a dishtowel.
Then the phone rang, and it was Citichild telling me she had just watched sunrise/moonset on the top of Cheehaw Mountain, the highest point in Alabama. During the night they had also driven past the highest points in North Carolina and Georgia. She wanted her grandfather's phone number. If she had been a bird she could have flown directly down the mountain to his rustic palace in the woods.
And speaking of birds. How did this one get inside and when? I've had the door closed most of the time due to either rainy or cold weather. It finally managed to find the open door and fly away, to find some real twigs and branches.
