archaeopteryx/hoatzin

[BPC.APA@email.apa.org (Considine, Blaise)]

 I may be way off base here, but I seem to remember the hoatzin being 
compared to archaeopteryx. If memory serves me, isn't the hoatzin a very 
poor flier, spending much of its time climbing and hopping from branch to 
branch? Also, aren't the young born with a couple of extra fingers for 
climbing back into the nest after dropping into rivers to escape 
predators? How valid is this comparison?
