Identifying and Displaying Images of Thirty Black and White Avian Species
The black-necked stilt (Himantopus mexicanus) is a captivating shorebird that calls American wetlands and beaches its home. This resident bird in South America can disperse as far as Florida in North America.
This diving and flying bird of prey spends most of its life in the water, only coming ashore to reproduce. The male and female of this species share the same plumage, with males usually being larger. They are primarily black with a white underside, making them easily recognisable.
Avocets, as they are commonly known, stick their bills into the mud and sweep it from side to side in order to prey on aquatic insects and other small creatures. They also have webbed feet, which aid in swimming.
The nest, made from sticks and greenery, has a diameter of about one meter. After roughly six weeks, when they are fully fledged, the chicks leave the nest and head out to sea, not to return for several years. They grow quickly while feeding on whole fish.
The black-necked stilt's distribution reaches Brazil, Peru, and the Galápagos Islands in the south via Central America and the Caribbean. In North America, they inhabit a variety of lowland forest types, ranging from semiarid to thick and humid.
About 31% of nests fledge a chick each year, with most chicks dying in the first two weeks. This is a testament to the challenges faced by these fascinating birds in their natural habitats.
Another interesting species is the American coot (Fulica americana), a bird only distantly related to ducks. Unlike ducks, coots have broad, lobed scales on their lower legs and toes, aiding walking on dry land. American coots have a diet primarily composed of algae and other water plants, although they will also eat small animals when available.
They are found throughout most of North America, with some individuals moving farther afield in the winter or following the breeding season. The American coot is the official bird of Newfoundland and Labrador.
In contrast, the Atlantic puffin (Fratercula arctica) is a seabird in the auk family, native to the Atlantic Ocean. Found in the Westman Islands, Iceland, it is the only puffin species native to the Atlantic. These black-and-white birds primarily congregate on North and Central American beaches and shores.
The osprey (Pandion haliaetus) is another fascinating bird of prey. This huge raptor measures more than 60 cm in length and up to 180 cm in wingspan. Its underparts and head are mostly grey, with brown upperparts. Foraging by touch, it needs shallow water to catch food, breeding when water levels fall.
The wood stork (Mycteria americana) is a big wading bird native to the United States. This bird nests colonially in trees, especially mangroves and Taxodium trees, surrounded by water. Its diet includes shrimp, crayfish, fish, and aquatic plants.
The black-necked stilt is a winter species that is only usually found on the Baja California peninsula. In Hawaii, there exists a solitary community referred to as the Hawaiian stilt.
The black-and-white hawk-eagle (Spizaetus melanoleucus) is a species of prey bird belonging to the Accipitridae family. This sizable member of the loon, or diver, family of birds is the common loon, or great northern diver (Gavia immer). The little auk, sometimes known as the dovekie (Alle alle), is the sole auk in the genus Alle.
Each of these species plays a unique role in their respective ecosystems, contributing to the rich biodiversity of North and South America. Understanding and preserving these species and their habitats is essential for maintaining a healthy and thriving natural world.
