Outside the window to my left there is a nest in our mulberry tree. Both parents are back and forth constantly, carrying wormy morsels for consumption by two tiny, hungry baby birds. I have been watching this beautiful process for about three weeks now, starting when I noticed the two adults putting the final touches to their compact little nest, right in front of the glass doors at one entrance to our house. If I wanted to I could clear the distance between the entrance and the tree in two or three strides, stand on the bench just beneath it, and reach up and touch the nest. At first I thought I was surely mistaken: why would they build so close by? Had they not noticed that there are people living here, using this very entrance several times a day? Not to mention our cat (okay, he’s elderly and has never climbed that tree, but he’s often in the area), and that all things considered they had best find another spot?
