wrensong

here's one I saw:

a tiniest bird, not but 2 inches from beak to tail and perched a meter from where I was passing, was caroling with all its soul. I stopped, awed into silence. This fruffy little tuft of a guy sang and chirruped like a lark or a wren and s/he put out sound that would have carried to the back of a large auditorium. It was utterly glorious.
