Are these characters accurate?

["Jason Michalak" <jasonbirder@hotmail.com>]

I just saw this website (http://www.evowiki.org/wiki.phtml?title=Aves) and 
wondered if what it is saying is accurate. It lists "Caudal tympanic recess 
opens with the columellar recess", "Caudal maxillary sinus present", 
"Prenarial aspect of premaxilla elongate", "Prezygapophyses reduced 
distally", "Pes anisodactyl" and "Teeth with characteristic root 
constriction (after Martin et al. 1980, Gauthier 1986, Chiappe 1995 and 
Chiappe et al. 1996)" as supporting the bird node. From my last stupid 
question I'm pretty sure the first and second are not accurate, but are the 
rest? The reversed hallux seems doubtful given some of the recent discussion 
anyway.
