The Sky Is Not Empty - a podcast by CAI

In the wild world, birds are the most commonly seen vertebrate, and, at this time of year—September into October—the Tree Swallow is probably the most commonly seen bird. These tiny green-and-white beings flock to our coastal areas by the tens of thousands. The Cape could be seen as Convention Central for them, as they congregate prior to migration south. They can be seen over ponds and lakes, over the dunes, and most especially up in the sky.
