A female cardinal is building her nest six inches from our dining room window.  She found a nice spot in the bushes, got herself comfortable, and began setting up house.  After about half an hour she froze.  For the first time noticed the people watching four feet away on the other side of the window.

She had been so preoccupied in setting pieces of grass, paper, and tissues she had totally missed us.  She stared contemplatively.  Scootched around in a circle, rounding out her nest, and checking her surroundings at the same time.  Finally she peeked directly at us again, turned her tail toward us and faced resolutely looking out toward the corn field directly opposite of us.

Humans gone.  Problem solved.
