. . . and honor to the squirrels of the nest in the Bradford Pear outside my window---the same nest I wrote about on Dec 13 in "Hey, Hawk!" Usually the squirrels build their nests too high in the trees to observe closely on a regular basis, but this one is low and near enough to the window by which I drink my early morning coffee that I've observed it all winter. I didn't see it being built, and only first noticed it when the leaves of the pear tree fell away in November. Watching a squirrel's nest on any given day could never be considered a rewarding habit, but in the course of a winter of morning meditations over coffee, enough activity has accumulated in my memory to be worthy of comment.
First there was the Dec 13 invasion by the Cooper's hawk who stabbed at the nest and threw out dry leaves amid the outrage of the house finches. I wondered at the time if the nest was active or abandoned, because as far as I knew, the hawk only searched it, and did not find a meal there before the finches chased it off.
The next noticeable activity came on the morning of the third day of continuously below-freezing temperatures after our January ice storm, in an observation that touched my heart. Two house finches were clinging to the underside of the nest, apparently gleaning the warmth that leaked from the nest's interior. I assumed this was an indication that at least one warm-blooded squirrel was burrowed inside the nest, and I liked to think it hinted at a cooperative living arrangement whereby the squirrels lent warmth to the finches in January in exchange for the favor of chasing the hawk from their nest in December. Whether by agreement or random response to a need makes no difference. That it happened at all was a phenomenon I found sweet and paradoxical, given the otherwise brutal nature of life in the wild.
Later we had a week of unseasonably warm weather between our Jan & Feb snows, and during that week two squirrels busied themselves bringing leaves to the nest in an industrious display of homemaking activity that I observed on only one morning. I know not if they were fortifying for another possible cold spell, or preparing for an upcoming birth, but I'm committed to watching them throughout the spring season, which seems suddenly to have arrived, if today's warm air and returning orchestration of birdsong are any indication. dkm
p.s. The photo of the nest in question was taken on the day after the light snow of Feb 9 & 10.
