Near the corner of Bleecker and Mercer, in early September 2014. Out hunting -- went for a mouse a moment later, under the cherry trees of the Bleecker Street greensward, and settled up in the high branches of a red oak. (Between buildings and trees, New York City is an amazingly rich cliff ecology for birds: wind shadows, safe ledges, a geography of promontories and canyons. A geology of iron, steel, and glass; Indiana limestone and New Jersey limestone; Catskills bluestone; countless tons of concrete -- raised up on a bed of Manhattan schist.) Whenever I have an opportunity to watch a hawk it teaches me more about how to be alive.
