[edit] "Cooper's" and "Cox's" sandpipers

An apparently new sandpiper species ("Cooper's Sandpiper Tringa/Calidris cooperi") was described in 1858 based on a specimen collected in 1833 on Long Island, New York. A similar bird was collected in 1981 at Stockton, New South Wales, Australia. These are probably hybrids between the Curlew Sandpiper ("Calidris" ferruginea) and the Sharp-tailed Sandpiper (Philomachus acuminatus/Calidris acuminata) (Cox 1990a; 1990b).

[edit] Other hybrid scolopacids

Putative hybrids between the Dunlin ("Calidris" alpina) and the White-rumped Sandpiper ("Calidris" fuscicollis) have been occasionally seen in northeastern North America (McLaughlin & Wormington, 2000, and external link below). In Europe, on the other hand, an apparent hybrid between the Dunlin and the Purple Sandpiper ("Calidris" maritima) has turned up (Millington, 1994).

Occurrence of intergeneric hybridization has been reported between the Buff-breasted Sandpiper ("Tryngites" subruficollis) and the White-rumped (or possibly Baird's, "Calidris" bairdii) Sandpiper[citation needed] - the parent species apparently do belong into the same genus, however (see calidrid) -, as well as between the Common and the Green Sandpiper (Tringa ochropus)[citation needed].

Hybridisation between American (Haematopus palliatus frazari) and Black Oystercatchers (Haematopus bachmani) is relatively common in southern California and adjacent Mexico (Jehl, 1985; Paulson, 2005[verification needed]).

The nearly extinct New Zealand Black Stilt (Himantopus novaezelandiae) hybridizes with the Pied Stilt (Himantopus leucocephalus), which is a major threat to the survival of the former species (Pierce, 1984).

光靠外表观察是鉴定不了新种的，要确认新种，需要取样作遗传基因的分析研究，但就是这样也不一定能解开谜团。

回复 3# 的帖子新物种？新物种，因为作为一个繁衍的物种，需要有一定的群体数量，鸻基本上分布在海滨，是观察资料最丰富的生境（与人迹罕至的森林山区很不一样），要是一百几十年都没有固定的发现，并不符合常理（就是黑嘴端凤头燕鸥，在19世纪也是有多个不同地区的文献及标本纪录的）
