When we moved in to our current home almost ten years ago, we opened the sliding glass door to the patio, and a momma robin darted away. As it turned out, she had made her nest right on top of the electrical meter just inches away from the door. All spring we had to be very careful until all of the babies flew away. I even left the nest all winter because, not being up on my birds, had no idea if she would return in the spring. Alas, she did not, so i confiscated the nest for decorating purposes. (not the eggs, they are from the craft store).
"A bird does not sing because it has an answer. It sings because it has a song".--Chinese Proverb
