Charadriiformes is a diverse order of small to medium-large birds. It includes about 350 species and has members in all parts of the world. Most Charadriiformes live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), some occupy deserts and a few are found in thick forest.
The order was formerly divided into three suborders:
The Sibley-Ahlquist taxonomy, which has been widely accepted in America, lumps all the Charadriiformes together with other seabirds and birds of prey into a greatly enlarged order Ciconiiformes. However, the resolution of the DNA-DNA hybridization technique used by Sibley & Ahlquist was not sufficient to properly resolve the relationships in this group, and indeed it appears as if the Charadriiformes constitute a single large and very distinctive lineage of modern birds of their own.
The auks, usually considered distinct because of their peculiar morphology, are more likely related to gulls, the "distinctness" being a result of adaptation for diving. Following recent research, a better arrangement may be as follows:
This is a list of the charadriiform families, presented in taxonomic order.
More conservatively, the Thinocori could be included in the Scolopaci (this combined sub-order is called Limicoli), and the Chionidi in the Charadrii. The suborders Thincori, Scolopaci, Chionidi, and Charadri are commonly referred to collectively as Waders. Some taxonomy sources place the Glareolidae family in its own suborder, instead of being classified under suborder Lari. The buttonquails are of indeterminate or basal position in the Lari-Scolopaci sensu lato group. The arrangement as presented here is a consensus of the recent studies.
