PAKHI DEKHUN PAKHI CHINUN (OBSERVE THE BIRD AND RECOGNIZE)...SECRETARY BIRD....WATERCOLOUR...The Secretarybird or Secretary Bird (Sagittarius serpentarius) is a large, mostly terrestrial bird of prey. Endemic to Africa, it is usually found in the open grasslands and savannah of the sub-Sahara. Although a member of the order Accipitriformes, which also includes many other diurnal raptors such as kites, buzzards, vultures, and harriers, it is given its own family, Sagittariidae. It appears on the coats of arms of Sudan and South Africa. First described by English illustrator John Frederick Miller in 1779, the Secretarybird was soon assigned to its own genus, Sagittarius, by French naturalist Johann Hermann in his Tabula Affinatum Animalium. It was not until 1935 that the species was moved to its own family, distinct from all other birds of prey—a classification confirmed by molecular systematics. Recent cladistic analysis has shown Sagittariidae to be an older branch of the diurnal birds of prey than Accipitridae and Falconidae, but a younger divergence than Cathartidae. Sometimes, the enigmatic bird Eremopezus is classified as an early relative of the secretary bird, though this is quite uncertain as the bird is only known from a few fragmentary body parts such as the legs. The earliest fossils associated with the family are two species from the genus Pelargopappus. The two species, from the Oligocene and Miocene respectively, were not discovered in Africa but France. The feet in these fossils are more like those of the Accipitridae; it is suggested that these characteristics are primitive features within the family. In spite of their age, it is not thought that the two specie are ancestral to the Secretarybird. The Secretary Bird is instantly recognizable as having an eagle-like body on crane-like legs which increases the bird’s height to as much as 1.3 m (4 ft) tall. This bird has an eagle-like head with a hooked bill, but has rounded wings. Body weight can ra
