I had to create a map for friends who will do a private waterfowl count so for your convenience heres a link to my Red Hook birding...
Red Hook can be combined with Brookyn Bridge Park for the long day....
only caveat > public transportation is limited. the B61 bus does go to IKEA and you can walk to the rest of the locations, its not very long..
