I live on Long Island as well! I too, have never seen a " tree frog". However, I have co-worker who lives in Northport ( 5 miles from me) - who sees them , often, all summer? She finds them on her screen door in the morning. She has described them as being a little more green though? I wish I had photos. I will ask her if she took any.

They come in green as well, and can change colour. Lots of samples in my albums if you want to see my locals. They are the only possibility according to Frogs and Toads of New York State - Identification Guide for a treefrog that's green in NY state. There are also links to their call on that page, it's a pleasant but pretty loud trilling. They'll trill in any warm and humid conditions, even now in the fall (though much less than in spring time) so you might still be able to locate them.
