Maybe you already know about this site?
Places to go birding in the area:
Avalon Jetty near 8th street--my cousin sees all kinds of sea birds there
The Cape May Harbor area--right now there is a Western Grebe there (at least it's been there the last month or more, I know 2 people who photographed it)
There has also been a Caracara sighting in Cape May and the shore areas.
(and I'm not talking about the one in the Cape May Zoo!)

Most the above places are within a half hour drive of Cape May and they are fairly close to each other, you could easily do more than one in a day. You can search each one on the NJ Wildlife Trails site, they include maps links on that site. I use the Google satellite view to check the places out to give me a good idea of what to look for and what is in the area.
You'll have a good time I'm sure in the Cape May area!
I am a novice birder and photographer who does it for the pure enjoyment.
