Shore Plover (Thinornis novaeseelandiae)

Also known as Shore Dotterel. The historical range of this species likely included the coastlines of New Zealand's South Island, and possibly North Island, but they were wiped out by introduced predators. A relict population survives on the Chatham Islands. Recently, captive-bred birds have been released on some New Zealand islands.

Javan Lapwing (Vanellus macropterus)

Sometimes placed in its own monotypic genus. Critically endangered and possibly extinct, this species was found in west and east Java, maybe Sumatra and Timor. Agricultural intensification and hunting has led to the demise of this species.

Monotypic

There are no pictures of this species in the Zoochat Gallery at the time of writing


Banded Lapwing (Vanellus tricolor)

Formerly placed in Lobivanellus or its own monotypic genus. This species occur throughout much of Australia and Tasmania. Absent in north Australia.

Sociable Lapwing (Vanellus gregarius)

Sometimes placed in the genus Chettusa. Critically endangered. Breeds in south-central Russia and Kazakhstan. Winters in Sudan, Eritrea, Israel and parts of the Arabian peninsula, as well as Pakistan and northeast India.

Monotypic

There are no pictures of this species in the Zoochat Gallery at the time of writing


White-Tailed Lapwing (Vanellus leucrurus)

Sometimes placed in the genus Chettusa. The breeding range of this species consists of several disjunct population. It occurs in central and eastern Turkey, eastern Syria and Jordan through Azerbaijan and Transcaspia to Lake Balkhash. Also in Iraq, Iran and west Pakistan. Recently recorded in Cyprus, Romania, and India. Winters in Sudan through Iraq towards Pakistan and India.

Monotypic

There are no pictures of this species in the Zoochat Gallery at the time of writing


Southern Lapwing (Vanellus chilensis)

Formerly placed in the genus Belonopterus. HBW considers splitting this species based on vocalisations. The range stretches over much of Latin America, with the exception of the very north, parts of the Amazon Basin and the Andes.

Often four subspecies recognised: cayennensis and lampronotus, according to the HBW, may constitute a separate species from chilensis and fretensis.

Andean Lapwing (Vanellus resplendens)

Formerly placed in monotypic genus Ptiloscelys, this species occurs in the Andes from southwest Colombia to north Chile and northwest Argentina.

Monotypic

There are no pictures of this species in the Zoochat Gallery at the time of writing



As an interesting addition, I found this picture of a hybrid lapwing in the Zoochat Gallery. It is supposedly a hybrid between a Masked and a Southern Lapwing (Vanellus miles x Vanellus chilensis), though it looks nothing like the two. A very interesting bird.

HAEMATOPODIDAE


The Haematopodidae contains the oystercatchers, a distinct group of nine shorebird species in a single genus. They all have distinct pied or black (or dark brown) plumage and brightly coloured bills. Mostly found in coastal environments, though some species occur inland. This family is sometimes contained within the Charadriidae, but is generally accepted as a separate family. There is some dispute on the number of species, with both the IOC and Clements bird list accepting two more species, as some forms considered subspecies by HBW are elevated to full species status.

Additionally, one species currently recognised by at least the IOC and Clements bird lists is considered extinct: the Canary Island (Black) Oystercatcher (H. mealdewaldoi). Populations attributed to this species were extripated by increased disturbance and competition by people around 1940 (Saenger, 1990; Ens and Underhill, 2014). However, recent genetic analyses by Shannon et al. (2019) place the species firmly within the range of genetic variation of the Eurasian Oystercatcher (H. ostralegus). They therefore conclude that it was a recent black morph of H. ostralegus, and not a separate species.

Haematopus



Magellanic Oystercatcher (Haematopus leucopodus)

This species occurs in southern South America, from south-central Chile and south-central Argentina in the north to Cape Horn and the Falkland Islands in the south. Shares many characteristics with old-world oystercatchers, and less with other new-world species.

Monotypic

Blackish Oystercatcher (Haematopus ater)

This species occurs mainly on the western coasts of the Americas. One subspecies breeds from the Aleutian Island through Alaska, Canada and the west coast of the USA towards Mexico, and winters mainly in British Columbia and Baja California. The other breeds on the west coast of South Amerika, from Peru to Tierra del Fuego, then north towards south-central Argentina. Has a broader range in winter.

Two subspecies recognised, with bachmani breeding in North America and ater in South America. Both subspecies are elevated to species status in the IOC and Clements bird lists.

ater - photo by @lintworm in the wild, Falkland Islands




American Oystercatcher (Haematopus palliatus)

Breeds along the coasts of the Americas. From the Gulf of California south to central Chile in the west, and from Massachusetts south to south-central Argentina in the east. A separate subspecies is endemic to the galapagos Islands.

Two subspecies recognized

African Oystercatcher (Haematopus moquini)

Occurs from northern Namibia south round the Cape of Good Hope, and then north again in the east towards south Angola.

Monotypic

Photo by @Kudu21 in the wild, South Africa




Eurasian Oystercatcher (Haematopus ostralegus)

Widespread species that breeds on Iceland, Scandinavia, western Europe including the British Islands, locally in southern Europe, west and north-central Russia south to the Black, Caspian and Aral seas and east to west Siberia. Further breeding populations occur in north-east Russia and South Island (New Zealand), both of which have an unclear taxonomic status and are sometimes treated as distinct species. Subspecies finschi from New Zealand has been associated with several other oystercatcher species, and has hybridised with H. unicolor (Crocker et al, 2010). Several other Oystercatcher species were included in H. ostralegus in the past, including moquini, ater bachmani, palliatus, chathamensis, unicolor and longirostris.

HBW recognises 4 subspecies, though the taxonomy is far from clear currently. IOC and Clements bird lists for example, recognise finschi as a distinct species.

Pied Oystercatcher (Haematopus longirostris)

The range of this species contains the coasts of Australia, Tasmania, Aru Islands and Kai Islands, as well as occasionally on the south coast of New Guinea, though probably non-breeding.

Monotypic

Chatham Oystercatcher (Haematopus chathamensis)

Sometimes included in H. longirostris or H. unicolor, with weak differentiation, though genetic studies seem to indicate full species status (Banks and Paterson, 2007). Endemic to the Chatham Island, where it is restricted to the coastal areas of Chatham, Mangere, Rangatira and Pitt. Occasionally at Star Keys. The only endangered oystercatcher species.

Monotypic

Variable Oystercatcher (Haematopus unicolor)

In the past considered conspecific with the H. chathamensis or H. ostralegus, this species is restricted to New Zealand, where it occurs in coastal areas of both North and South Island, as well as adjacent islands. H. ostralegus finschi was once taught to have been a pied morph from of this species, and the two have hybridised multiple times (Crocker et al, 2010).

Monotypic

Sooty Oystercatcher (Haematopus fuliginosus)

This species occurs along much of the coasts of Australia, Tasmania and surrounding islands. Has occasionally hybridised with H. longirostris. HWB argues that there’s a case to raise both subspecies from the Sooty Oystercatcher to full species status, as there is no good evidence of interbreeding. However, more research is necessary, especially as there is confusion about the range limits of both subspecies.

IBIDORHYNCHIDAE



The Ibidorhynchidae is a monotypic family, containing only the highly distinctive Ibisbill. It is one of the enigmatic odd-ball species that are found within the Charadriiformes. The Ibisbill is often associated with the Recurvirostridae and the Haematopodidae, and was found to be a sister species to the latter (Baker et al, 2007).

RECURVIROSTRIDAE



The recurvirostridae is another very distinct family of waders, and contains the avocets and the stilts. This family contains 3 genera, 7 species and 11 taxa, as recognised by the HBW. It should be said the IOC and Clements bird lists recognise several more Himantopus species, which HBW surprisingly lumps into two species. According to them, the differences between the H. himanotopus s.l. forms are slight, mostly based on the black patterns on the neck and minor vocal differences. They conclude that there is not enough evidence to split the species, and they recognise it as a cosmopolitan species with a lot of variation and several subspecies. There is surprisingly little data on the phylogeny of this family.

Himantopus



Black-Winged Stilt (Himantopus himantopus)

This species is cosmopolitan and in found on all continents except Antarctica. It occurs in western and southern North America, much of Latin America except the Amazon Basin; throughout Europe (except the north) and through central Asia towards north-central China, the Indian subcontinent, Indochina and Southeast Asia. Also found in Australia, New Zealand and throughout Africa except the Sahara and the Congo Basin. The taxnomy used by HBW is not universally accepted, as both the IOC and Clements bird list elevate several subspecies to full-species status (both mexicanus and leucocephalus, with IOC also recognising melanurus as a separate species). According the HBW, the variation is limited and mostly based on the “amount and distribution of black on the neck”, which they deem insufficient evidence to split the species (Pierce and Kirwan, 2020). There is a notable lack of research on this species complex.

HBW recognises five subspecies. IOC and Clements bird lists also recognise five taxa, but respectively classify them as either four or three species with subspecies.

And that wraps up the Charadrii! I should say that there were a lot more species represented in the gallery that I had imagined when I started the thread. Nonetheless, there are 28 species of Charadrii that are not yet represented. The far majority (26) are Charadriidae, and mostly within the Charadrius genus, though there are a fair few Vanellus also lacking. Outside that family we have al almost complete photographic guide, with only a single missing species in both the Haematopodidae and Recurvirostridae. Given that a fairly large chuck of the missing species does occur in areas that are or have been visited by Zoochatters, I suspect a few more species could be added over time or have been photographed by Zoochatters but not uploaded (yet). Of course, clearer pictures or photos of missing subspecies are just as welcome.

The missing species are:

Charadriidae
Southern Red-Breasted Plover (Charadrius obscurus)

CHIONIDI


The Chionidi is a relatively basal suborder that is mostly associated with the Charadrii, as either the Chionidi families are thought to be basal to the Charadrii, or they form a monophyletic sister group to them (Thomas et al, 2004). It generally contains three small families - Thick-Knees, Sheathbills and the Magellanic Plover - that generally cluster together, even though they are highly distinct at first glance (Baker et al, 2007). Basically, the group is an assembly of odd-ball families common in the Charadriiformes. However, there is a fourth family sometimes associated with the other Chionidi, and that is the one is much more difficult to place.

One the most enigmatic species of shorebirds, at least phylogenetically, is the Egyptian Plover (Pluvianus aegyptius). Originally it was placed within the Glareolidae, along with the coursers and pratincoles, among other things based on natal plumage (Lowe, 1931). Although that placement would be questioned every now and then, it was only since the late 1970’s that osteological data placed the species as a sister of the Burhinidae (Strach, 1978, Chu, 1995). A more recent morphological study by Mayr (2011) reached the same conclusion, and identified several synapomorphies. However, most molecular studies have placed the species - now generally accepted to belong in a monotypic (sub)family - basal to the Charadrii clade, such as the multilocus study by Fain and Houde (2007), as well as Baker et al. (2007). Fain and Houde also note that most synapomorphies attributed to the Burhinidae + Pluvianus clade may be symplesiomorphies of basal Charadriiformes.

I have yet to see a truly convincing case for the placement of Pluvianus, though all current data points to its placement outside the Glareolidae. I have chosen to discuss the species here, though be aware that its phylogenetic placement is far from certain. As such, the Chionidi as discussed here contains four families.

BURHINIDAE



The Thick-Knees, also called Stone Curlews, are a group of mainly terrestrial waders with long legs and mostly short bills. There is little controversy on Burhinidae taxonomy. However, recent studies on Eurasian Thick-Knees identified genetic patterns different from the current subspecies classification (Mori et al, 2014, Mori et al, 2017). The classification of the Burhinidae may thus not be as clear cut as it seems.


Burhinus - (8 species of Thick-Knees)

Esacus - (2 species of Thick-Knees)

Burhinus



Eurasian Thick-Knee (Burhinus oedicnemus)

This species has a wide but scattered distribution from western Europe and the mediterranean east through the Balkans, Transcapia and Turkestan towards east Kazakhstan, south through Iran to Pakistan and the Middle East. Also found on the Canary Islands. Wintering populations can be found in and south of the Sahara in Africa and the Arabian Peninsula.

HBW recognises 5 subspecies but note that assigning them is difficult. Recent papers (Mori et al, 2014 and Mori et al, 2017) have identified genetic clusters which do not always correspond with the subspecies classification (especially regarding saharae).
