Nesting Tree Swallow in Morning Light

A Tree Swallow gathers nesting material in the spring during morning light in SE Michigan, Metro Detroit. A buddy and I photographed this swallow for quite a while that morning as it was quite accommodating near its nest. It made many trips with many feathers into the hole of its nesting tree.
