As we were exploring the Namekagon Wildlife Barrens in northwestern Wisconsin we saw many bluebird houses distributed throughout the area. Numerous agencies and individuals have worked hard to be sure the birds have access to good nesting areas. At one road junction we stopped and watched this tree swallow as it flitted in and out of the house, flying to the trees nearby, then coming back to the house. He was accompanied by a female which came and went many times too. What a delight to let time stand still and watch their activities and absorb this little bit of spring!
