Hi leewee,
Check out Brigantine National Wildlife Refuge, exit 48 on Garden State Parkway. Drive south on Route about 6 miles, watch for sign on left. 20,000 acres of coastal marsh, bays, channels, fields, brush. Brig is outstanding for shorebirds in the fall. Check the "book" in the little house by the toilets to see what has been seen, drive the loop that takes you out to the marsh and bisects two large tidal lakes, snow geese, assort. ducks, raptors, loads of shorebirds.
Cape May- Check Cape May Bird Observatory on Lake Drive on Lilly Lake. Check "Birder's Log" for recent sightings, about 2 blocks down is the Lighthouse where all the action is for Hawk Watch. Tallies have been kept since 1976, peak flights are in September-October. 1981 had a total of almost 89,000. That should get you excited! Sharpies dominate the list with a smattering of coopers. Osprey's are seen daily, Merlin and Peregrine coursing through the trees looking for an easy meal.
Make reservations now for a room or you will be spending an hour driving back up north for one. Enjoy your visit.
