and what now?

The most significant question the article raised for me was: what has happened since? The authors assert that they cannot be sure whether any mating pairs were present, or even whether all sightings were not of a single individual. Seeing as considerable evidence was gathered, I would assume that this case is one that's been followed up with further research. We may be getting to this in a few days, but I wonder most whether researchers continued to attempt to track these birds, especially during mating season, which (if there were in fact mating pairs present) would probably be accompanied by certain rituals or distinctive calls that could offer more concrete evidence (and legitimate hope for continuation of the species). I'd like to see the results of this, as well as the ultimate outcome to date, if information is available, to know whether people's attempts at habitat restoration have been successful.
