Tree Swallow

Nurse: “The invisible man is here for his appointment.”

Doctor: “Tell him I’m sorry I can’t see him right now.”

Interesting Fact: Tree Swallows nest in natural cavities of standing dead trees, old woodpecker cavities, or nest boxes. On occasion they nest in hollow stumps, building eaves, Wood Duck nest boxes, holes in the ground, old Cliff Swallow burrows, or other unconventional sites.  ( https://www.allaboutbirds.org/guide/Tree_Swallow/lifehistory )
