Re: FLAMINGOES ARE STILTS

Actually I should have been more specific and said recurvirostrids
instead of stilts (or avocets). I meant recurvirostrids (even though
they are the same as avocets and stilts).
Regardless, stilts (actually all Charadriiformes) are similiar to
phoenicopteriformes. The closest group is the Recurvirostridae and the
single closest genus is the Australian banded stilt, _Cladorhynchus
leucocephalus_, which is extremely similiar in osteology, ecology,
feather anatomy, behavior and life history. And lets not forget
Palaelodidae, which are thought to have split off from the flamingo
common ancestor about the same time as _Juncitarsus_.

Well, I think that he was probably right. The acrocoracoid is identical
in the two groups of birds (in its curved internal side and lack of
pnematic foramina; and from ventral view, the small ledge). As well as
the rest of the coracoid with the small procoracoid, flattened shaft,
etc. And the incised sternum. These features are not seen the same way
in lithornithids and are certainly (and understandably) absent in
