May be and we can hope and good not to give up. I don’t know either way. Of course the issue would be, is he seeing Night Parrots or is he seeing night parrots. As in is it that species or some other species flushed from the ground at night that may be a parrot and thus given that name. Presumably lots of birds roost on the ground and is he identifying them as separate? Surely most birds roosting on the ground would flush in front of a nocturnal grader. It is worth ascertaining what other birds he sees in that situation. If he is calling all (or even a large proportion of) birds seen that way as being Night Parrots, then they probably aren’t.
Not that different, I once heard a NP Ranger in a Victorian coastal park asked whether there were Ground Parrots around. His answer delivered with some amazement at how dumb the question was: yes ground parrots are all over the place, like these and pointed to Crimson Rosellas feeding on the ground in the picnic area. Without the capital letters his answer was correct.
