Hi Martin,
Equally, adults would be more experienced and less easy to shoot. And there's the possibility that juveniles were being missed through no-one knowing what they looked like.
I guess breeding productivity would have collapsed in recent years due to birds being unable to find mates, but so far as I can see from the paper in BB July '02, there doesn't appear to be a significant problem with habitat loss on the presumed breeding grounds. Unless they mostly bred in habitats different to where Ushakov found his. Maybe his were at the northern edge of the range and they mostly bred on drier steppes which are now cultivated?? - but there's no evidence for this.
