Five wader families from the Charadriiformes order of birds feature in the galleries.
The gallery features four species belonging to the Haematopodidae family:
(a) The IUCN categorisation for the Eurasian oystercatcher is globally near threatened and in the European region vulnerable; the image was taken on Skomer Island during the early nineties, when it was categorised as least concern.
(b) I photographed the pied oystercatcher at Lakes Entrance in Australia, it's also found in the Indonesia and Papua New Guinea.
(c) South Island pied oystercatcher (Haematopus finschi) is not recognised by Birdlife International (Ref 2) as a separate species or subspecies (H.o. finschi). H. ostralegus the Eurasian Oystercatcher was split into H. ostralegus and H. finschi Sibley and Monroe (1990, 1993), del Hoyo and Collar (2014) lumped them back together. However, most other sources list Haematopus finschi including IOC World Birds List (Ref 4). It's consider to be a New Zealand endemic.
(d) Another New Zealand endemic is the variable oystercatcher that I photographed in its black phase in Stewart Island.
On the coast Oystercatchers feed on molluscs, bivalves and crustaceans.

Eurasian Oystercatcher (Haematopus ostralegus) [NT] [VU in European and EU regions]
Six genus and eight species of sandpiper (Scolopacidae) family are featured:
(a) The near threatened Bar-tailed godwits (Limosa lapponica) migrate to Australasia from their breeding grounds in Alaska, possibly the longest journey of any migratory bird. The image is the New Zealand subspecies baueri (eastern bar-tailed godwit) that I photographed at Okarito wetland.
(b) Two birds from the Tringa genus; the common redshank and common greenshank over-wintering at Sungei Buloh wetland reserve in Singapore.
(c) A couple of birds from the Numenius genus; the Eurasian curlew photographed at Skomer Island in the early eighties and whimbrel at Papanui Inlet in New Zealand.
(d) Ruddy turnstone (Arenaria interpres); two images, one photographed on the beach on the Indian Ocean island of Seychelles, so probably A.i. interpres and the second on the mudflats on the Caribbean island of Trinidad, so probably A.i. morinella.
(e) Sanderling (Calidris alba); photographed on anse Bazarca beach in the Seychelles.
(f) Spotted Sandpiper (Actitis macularius); photographed on the Trinidadian beach of Grande Riviere.
Sandpipers mainly eat invertebrate from the mud and sand.

Three families/genus and four species are featured:
(a) Wattled Jacanas belongs to Jacanidae family. Photographed at La Vaga Lakes in Trinidad where it feeds on insects, invertebrates and seeds from the water and vegetation.
(b) Images of two species from the Plover (Charadriidae) family; Adult and immature crab plovers on the beach in the Seychelles where they eat their preferred food – crabs and a masked lapwing, an Australian native feeds inland on insects, larvae and earthworms.
(c) The images of the Black-winged Stilt that belongs to the Recurvirostridae family was photographed at the Sinclair Wetlands in New Zealand.
