SHOREBIRDS

Most Shorebirds walk along shores probing for food with their thin sensitive bills. Bill length varies considerably so differing species can work the same shore and obtain different food supplies. Shorebirds include sandpipers, godwits, stilts, oystercatchers, plovers, and many more. Shorebirds belong to the Charadriiformes order which also includes the Gulls and Allies.
Note: the term Shorebirds is used in the Americas; elsewhere "waders" is used. We will reserve "waders" for herons and allies.

Some Charadriiformes families:
Burhinidae: thick-knees; Charadriidae: small plovers, lapwings; Glareolidae: courses, pratincoles; Haematopodidae: oystercatchers
Jacanidae: jacanas; Recurvirostridae: avocets, stilts; Scolopacidae: small bill sandpipers, large bill sandpipers.


Oystercatchers

Order Charadriiformes    Family Haematopodidae - 1 genus

Oystercatchers are the only types of bird in family Haematopodidae. They have two different type of plumage: pied or black. The pied oystercatcher has mostly black plumage including the head, neck, and tail. The black type has all black plumage. The variable oystercatcher is an except; some subspecies are all black, but others have some white on the underparts, but none as much white as the pied oystercatchers.

All oystercatcher have a brightly colored long and straight bill which is red, orange, or something in between. The tip of the bill may be blunt or pointed, that shape being mainly determined by how it is used. If the bill is used to hammer and pry at shells, it will become rounded with wear. If it is used to do soft jobs such as dig for worms, it will be sharper. Oystercatchers all have eye-rings, and they, along with the eyes are brightly colored too: red, orange, or yellow. The legs vary from white to red.

Oysters are not high up on the list of an oystercatcher's food list. But they do have the unique ability to be able to open and oyster shell, and that merits their name. Mollusks in general are a favorite food for most oystercatchers, and they too require opening. Limpets are a similar food, but instead of being bi-valved, they only have one shell. They are really a type of snail. Other foods are sea urchins, starfish, crabs, and worms. The worms are not just aquatic worms, but some oystercatchers during breeding season will frequent pastures and seek earthworms and insect larvae.

The nest a scrape in the sand or ground. They may be a little vegeation placed in the nest, or even small pebbles. The eggs are patterned with specks for camaflauged. They are incubated by both parents for about 32 days.
