Alan Feduccia did write once that avian diversity did encounter a
bottleneck at the end of the Cretaceous only to experience a boom
afterwards. The enantiornithines, of course, were the victims, while the
neornithine basal stock acted as the progenitors of today's current avain
fauna (with his shorebird-duck, shorebird-flamingo and shorebird-ibis
mosaic forms).

BTW, anyone have Feduccia's address? A former colleague of his is back here
in the Philippines and hasn't contacted him in a while.
