I try to lunch outside at least once a week while the weather is warm. It's a mini picnic with table and chairs. A bluebird pair has been in the yard this week and during lunch I got a good chance to watch them. I thought they were feeding (dining al fresco) but they were busy collecting little green worms to carry off obviously to a box full of babies. They did not fly out of the yard until they had a beak slam full of green worms!
