The Dawn Chorus

Aves cantantes secundum parallelos  ·  a globe, and the birds of one parallel

A terrestrial globe, engraved, turning on its stand. Ride the ring down the brass meridian and it stops on a latitude — and everything iNaturalist has ever recorded singing between those two parallels begins, at once, as loudly as everything else. The light on the globe is this minute's: the sun's place is computed from the clock, and the vermilion arc is where dawn is breaking right now.
