eaves

architecture earns life. a swallow pair looks for a real overhang — solid block above, air below, a wall face beside; an honest little detection, no special block to buy — and builds a mud cup under it over a day or two of visible trips to the nearest water and dirt. you can watch it happen: a first daub stuck to the wall, then a rim raised around it, then the finished cup with a lip to sit on. the nest is theirs, then it is the house's: it holds through winter empty, and next spring's pair prefers an old cup to any new build. a lived-in house accumulates them; two years writes a history in mud.

at dusk they hunt low over open water and open field — long fast passes a half-block off the surface, the single most alive thing a pond does all day. when autumn leans they gather on the fences and rooflines for one restless day, and the next morning they are simply gone, all at once. the almanac, when it is home, gets its two best lines a year: the swallows came back; the swallows left. without the seasons, an endless mild season — swallows simply resident.

they cost nothing and ask nothing: no taming, no feeding, no droppings, no chore. the relationship is that they chose your house. a deliberate hit on a nest takes it down — one mud daub back, and a small shame.
