I recoreded a few Birdsongs, before I realized I couldn't, in good faith, use them.

You see, the Parrots of Telegraph Hill make a brief stop each day in the Presidio where I work, perching for a moment on the Palm Tree outside my window. And they make the most amazing noise. So I waited untill they were particularly noisy, and caught a few good seconds of tropical chatter before they sped of for locales unknown.
