John James Audubon - ජෝන් ජේම්ස්

   




John James Audubon 1785-1851
The American Woodsman: Our Namesake and Inspiration

John James Audubon (1785-1851) was not the first person to attempt to paint and describe all the birds of America (Alexander Wilson has that distinction), but for half a century he was the young country’s dominant wildlife artist. His seminal Birds of America, a collection of 435 life-size prints, quickly eclipsed Wilson’s work and is still a standard against which 20th and 21st century bird artists, such as Roger Tory Peterson and David Sibley, are measured.

Although Audubon had no role in the organization that bears his name, there is a connection: George Bird Grinnell, one of the founders of the early Audubon Society in the late 1800s, was tutored by Lucy Audubon, John James’s widow. Knowing Audubon’s reputation, Grinnell chose his name as the inspiration for the organization’s earliest work to protect birds and their habitats. Today, the name Audubon remains synonymous with birds and bird conservation the world over.

Audubon was born in Saint Domingue (now Haiti), the illegitimate son of a French sea captain and plantation owner and his French mistress. Early on, he was raised by his stepmother, Mrs. Audubon, in Nantes, France, and took a lively interest in birds, nature, drawing, and music. In 1803, at the age of 18, he was sent to America, in part to escape conscription into the Emperor Napoleon’s army. He lived on the family-owned estate at Mill Grove, near Philadelphia, where he hunted, studied and drew birds, and met his wife, Lucy Bakewell. While there, he conducted the first known bird-banding experiment in North America, tying strings around the legs of Eastern Phoebes; he learned that the birds returned to the very same nesting sites each year.

Weaver Bird - වඩු කුරුල්ලා




The Ploceidae, or weavers, are small passerine birds related to the finches.

These are seed-eating birds with rounded conical bills, most of which breed in sub-Saharan Africa, with fewer species in tropical Asia and also in Australia. The weaver group is divided into the buffalo, sparrow, typical, and widow weavers. The males of many species are brightly coloured, usually in red or yellow and black, some species show variation in colour only in the breeding season.

Weaver birds, also known as weaver finches, get their name because of their elaborately woven nests (the most elaborate of any birds'), though some are notable for their selective parasitic nesting habits. The nests vary in size, shape, material used, and construction techniques from species to species. Materials used for building nests include fine leaf-fibers, grass, and twigs. Many species weave very fine nests using thin strands of leaf fiber, though some, like the buffalo-weavers, form massive untidy stick nests in their colonies, which may have spherical woven nests within. The sparrow weavers of Africa build apartment-house nests, in which 100 to 300 pairs have separate flask-shaped chambers entered by tubes at the bottom. Most species weave nests that have narrow entrances, facing downward.
