Night was falling. Birds were singing. Birds were, it occurred to me to say, enacting a frantic celebration of day's end. They were manifesting as the earth's bright-colored nerve endings, the sun's descent urging them into activity, filling them individually with life nectar, the life nectar then being passed into the world, out of each beak, in the form of that bird's distinctive song, which was, in turn, an accident of beak shape, throat shape, breast configuration, brain chemistry: some birds blessed in voice, others cursed; some squeaking, others rapturous.
