THE WORLD BIRDS - An Online Bird Book
SHOREBIRDS
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.

Thick-knees
Order Charadriiformes Family Burhinidae
Order Charadriiformes Family Burhinidae
Thick-knees are so named because of their prominent joints on their long yellow or greenish legs. They are also called stone-curlews because of their similarities to curlews, but they are not close relatives. Even though they are clasified as waders, they have a preference for arid or semi-arid areas. They have yellow eyes and heavy black or yellow black bills. They are mainly nocturnal. The diet consist of insects, other small invertebrates, and somtimes small lizards or small mammels.
