Hanging out at birding hotspots, like Magee Marsh, Cape May, the Rio Grande Valley of Texas and the like greatly increases ones odds of finding a "life plate". Below are a few from my collection, nearly all from my home state of Ohio.
One of my favorites. It's clever. And in code. A birder will know it's meaning, though - sort of like a secret handshake.
If you've got any cool bird plate photos, send 'em along.
