Pappa Wren almost always announces his arrival. He had several of this type of bug when he came in. Sometimes he had to wait for the Mrs to leave the nest before he would feed them. I figured that is why he usually announced his arrival.Sometimes one of the little ones would meet him at the door. I don't think he played favorites because he would push on through the door rush and disappear.
Then of course someone has to do the housekeeping. I believe that the Momma is usually the one that takes the fecal sacs away from the nest. Difficult to tell when the birds are zipping in and out so quickly.
Maybe I will be able to sit here when the sun is shining some time to get some really good pictures before the babies fledge. I will also trim a branch or two. However when the sun is shining I am usually working in the garden now. There never seems to be enough time to do the things we want to. Sigh~~
