Just a couple of points i noticed in a quick glance at the article.
"Some, like Hoatzin, doves, and flamingos, also are unique in feeding their young esophageal secretions."
If the animal feeds its young cud, I think it is technically inaccurate to call it secretions. Phlegm is an esophageal secretion, cud is stomach regurgitate.
"Species: O. hoazin"
Another technical point. The Genus: Opisthocomus is correctly pointed out, but the species would just be "hoazin." Genus/Species of Opisthocomus hoazin.
Comments?
- Can you call something unique if others have a similar property? How about unusual? 209.183.190.169 12:41, 19 July 2006 (UTC)

- Technically it is not "cud," as cud comes from the stomach, but the hoatzin brings it back up from the crop. This is not the same as crop secretions (think "pigeon milk")--only feeding a chick crop secretions would be like feeding your child enzymes without the food the enzymes are meant to process. 71.217.114.221 03:06, 19 January 2007 (UTC)
[edit] Notarium?
"While the hypothesis of their relationship is based on DNA, it is notable that these birds share some obscure anatomical features, e.g., the notarium - a fused series of thoracic vertebrae." - I have removed this sentence from the Metaves discussion, because I can't seem to find a source (searched notarium metaves and notarium hoatzin flamingo on Google). It seems not all to implausibe though and would somewhat strengthen the case for the Metaves being if not a clade then composed of clades and not dominated by homoplasies. So if a source is available, please add. Dysmorodrepanis 11:51, 28 February 2007 (UTC)
