CHARADRIIDAE (20 species)

Phillips (1980) studied courtship and related behaviors in endemic NZ plovers and concluded that Anarhynchus be merged with Charadrius. Phillips (1980) also proposed that C. bicinctus Double-banded Plover, C. (=Anarhynchus) frontalis Wrybill, and C. obscurus Red-breasted Dotterel are closest relatives of each other and are derived from the C. alexandrinus Kentish Plover group of northern hemisphere mountain- or plains-breeding plovers. Phillips (1980) postulated that ancestral wintering birds bred in NZ during the austral summer and founded the now-endemic NZ species studied.

Haematopus ostralegus Eurasian Oystercatcher
H. o. osculans Cas Ogasawara Is, Iwo Is. Acc Mariana Is (Guam, Reichel and Glass 1991).

H. finschi South Island Pied Oystercatcher

NOTE: Treatment of finschi as an allospecies of H. ostralegus and of longirostris and unicolor as allospecies of each other (Sibley and Monroe 1990) appears logical, based on appearance and behavior. Data in Baker (1977; see Christidis and Boles 1994) suggest that longirostris and unicolor are more closely related to palliatus than to the ostralegus group.
In recent years this species has begun breeding in east coast South Island sand dunes with unicolor, resulting in hybrids and backcrosses, which resemble finschi but with smudgier features (Crocker et al 2010).
Records from Lord Howe I and Norfolk I previously attributed to H. longirostris Australian Pied Oystercatcher now are more likely this species based on accumulating evidence (McAllan et al 2004).
