The last time I saw one, it was sitting on the shoulder of Big Foot.
Seriously, there have been reported sightings of the bird in the swamps of Louisiana and on timber land in Alabama. Most reports of researchers I’ve read seem to look in most easily accessible land while never venturing off the beaten paths.
I suspect, just as many birds and animals thought extinct but of which sightings have eventually been reported, they have been pushed into smaller and smaller habitats where humans seldom venture. And of course they make themselves scarce when the hear the sounds of human activity. They are there, they just don’t want to be seen.
