Wildlife in Guatemala: A Willet is seen looking for food on a beach in Guatemala

A Willet is seen foraging in the Las Lisas beach, in Guatemala. The willet (Tringa semipalmata) is a large shorebird in the family Scolopacidae. It is a relatively large and robust sandpiper and is the largest of the species called "shanks" in the genus Tringa. It breeds in North America and the West Indies and winters in southern North America, Central America, the West Indies and South America. Two subspecies (which may actually be different species) have very different breeding habitats. The eastern willet breeds in coastal saltmarshes while the western willet breeds in freshwater prairie marshes, sloughs, potholes and other inland wetlands. In winter both subspecies are coastal birds being found on both rocky and sandy coasts as well as on mudflats and in coastal marshes. They are territorial both on the breeding grounds and on the wintering areas but form loose breeding colonies or wintering groups. When displaying the wings are held stiffly and downcurved in flight while on the ground the display gives prominence to the distinctive pattern of the underwings. They are normally vigilant birds, with the birds closer to the landward edge of a saltmarsh being the first to utter their alarm calls. Willets are flexible in their feeding habits and hunt by walking steadily and pecking prey from the substrate, although they also probe into the mud or silt with their sensitive bill and may actively stalk larger prey in shallow water. A favored prey on the coasts is small fiddler crabs as well as mole crabs, worms, clams and other invertebrates. They have also been known to occasionally eat plant material. Willets also actively hunt more mobile prey such as fish and aquatic insects in the water and will wade up to their bellies to pursue such prey.
