DS:  Cape May is shaped like a giant funnel at the southern tip of New Jersey, so any bird migrating south through the state is concentrated into the narrow peninsula. When the weather is right in the fall (cold temperatures and N or NW winds) the number and variety of birds at Cape May can be staggering, and the best thing is that you can just sit in one spot and watch them all pass by like a river.

DS:  Many many memorable experiences, all related to migration. One morning in the late fall I went out at first light and the sky was just filled with Great Blue Herons - thousands of them - in flocks, milling around at all heights from just over the treetops to so high they were barely visible. They dispersed quickly, and within a couple of hours most of them had vanished, but that scene at dawn was very memorable.
