This is Burtnot. In North America, it's winter. Not a bad time to head for the subtropical

realms of South Florida and listen in on some of the region's birds. Those are the sharp

edged phrases of a white-eyed virio. This small, skulky songbird is a full-time resident

of Florida and might sing it any time of the year. Their lurks are more secretive bird

in the Everglades and Florida Keys, the mangrove cuckoo. Rarely seen, it sings sporadically

in winter, but when it does, you'll know it. A sweeter voice belongs to the spot-breasted

oil. Found in suburban neighborhoods around southeast Florida, spot-breasted oils were

first brought to Florida in the 1940s from Central America. Our final stop takes us to a

wooded swamp, home to one of the continent's most peculiar birds, and with a voice to match.

It's a waiting bird called Olympkin. Tall, brown, long-beaked. Its eerie cry is unmistakable.
