In fact, the quoted 1700 miles is roughly 25 degrees of latitude, which I don't believe would get to you South America, starting from Nova Scotia.
Although not as far, the much smaller (.15oz versus 4.2oz) ruby-throated hummingbird makes a lengthy, non-stop trip across the ocean as well. Their average trip entails a 500-600 mile journey from the Southern United States over the Gulf of Mexico to Central America and then up to 1000 miles more over land. Unlike the warbler, hummingbirds leaving from Louisiana or Texas have no land mass in between, so they're most assuredly going non-stop.
Edit: not sure why I was downvoted. Did I make a mistake?
Maybe it wasn't intentional. I know some people accidentally mash the wrong arrow on mobile devices and you can't take back a vote.
