podicipediformes การใช้

• This is a "'list of Podicipediformes species by global population " '.
• The " Passerae " are one of the most seriously flawed systematic proposals in modern ornithology, perhaps rivalled only by the suggestion ( based as it was on early cladistic analyses ) that Hesperornithes, Gaviiformes and Podicipediformes form a monophyletic group.
• Namely, other recent authors have considered loons to share a rather close relationship with seabirds such as penguins ( Sphenisciformes ), tubenoses ( Procellariiformes ), waders ( Charadriiformes )  and perhaps the newly discovered clade Mirandornithes which unites grebes ( Podicipediformes ) and their closest living relatives, the flamingos ( Phoenicopteriformes ).
