Charadriiformes (

pelagic
(seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds.

Taxonomy, systematics and evolution

The order was formerly divided into three suborders:

  • The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments.
  • The gulls and their allies (or "Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments.
  • The auks (or "Alcae") are coastal species which nest on sea cliffs and "fly" underwater to catch fish.

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.[6]

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.[7]

Families

The order Charadriiformes contains 3

suborders, 19 families and 391 species.[8][9]

Evolutionary history

That the Charadriiformes are an ancient group is also borne out by the fossil record. Alongside the

mya
. Basal or unresolved charadriiforms are:

  • "Morsoravis" (Late Paleocene/Early Eocene of Jutland, Denmark) - a nomen nudum?
  • Jiliniornis (Huadian Middle Eocene of Huadian, China) - charadriid?
  • Boutersemia (Early Oligocene of Boutersem, Belgium) - glareolid?
  • Turnipax (Early Oligocene) - turnicid?
  • Elorius (Early Miocene Saint-Gérand-le-Puy, France)
  • "Larus" desnoyersii (Early Miocene of SE France) - larid? stercorarid?
  • "Larus" pristinus (John Day Early Miocene of Willow Creek, US) - larid?
  • Charadriiformes gen. et sp. indet. (Bathans Early/Middle Miocene of Otago, New Zealand) - charadriid? scolopacid?[12]
  • Charadriiformes gen. et sp. indet. (Bathans Early/Middle Miocene of Otago, New Zealand) - charadriid? scolopacid?[13]
  • Charadriiformes gen. et sp. indet. (Bathans Early/Middle Miocene of Otago, New Zealand) - larid?[14]
  • Charadriiformes gen. et sp. indet. (Sajóvölgyi Middle Miocene of Mátraszõlõs, Hungary[15]
  • "Totanus" teruelensis (Late Miocene of Los Mansuetos, Spain) - scolopacid? larid?

The "transitional shorebirds" ("

and few if any are still believed to be related to the well-distinct waterfowl. Taxa formerly considered graculavids are:

Evolution of parental care in Charadriiformes

Shorebirds pursue a larger diversity of parental care strategies than do most other avian orders. They therefore present an attractive set of examples to support the understanding of the evolution of parental care in avians generally.[18] The ancestral avian most likely had a female parental care system.[19] The shorebird ancestor specifically evolved from a bi-parental care system, yet the species within the clade Scolopacidae evolved from a male parental care system. These transitions might have occurred for several reasons. Brooding density is correlated with male parental care. Male care systems in birds are shown to have a very low breeding density while female care systems in birds have a high breeding density. (Owens 2005). Certain rates of male and female mortality, male and female egg maturation rate, and egg death rate have been associated with particular systems as well.[20] It has also been shown that sex role reversal is motivated by the male-biased adult sex ratio.[21] The reason for such diversity in shorebirds, compared to other birds, has yet to be understood.
