Anas platyrhynchos(Birds)

Nilashir (scientific name: Anas platyrhynchos) or indigo poultry Anatidae (Anatidae) family or anas (Anus) belongs to the family
Large ducks of species. [2] [3] Birds are also found in North America, South America, Europe,
It is seen in different countries in North Africa and Asia. New Zealand
The species is released in Australia. Nilshir's scientific name means a large duck (Latin: anus = duck;
Greek = platurhunkhos = wide lips). [3]
As a universal species, they spread across a vast area around the world, their quarters of some 22 million square kilometers area.
[4] Over the past few decades, their number has decreased, but they have not yet reached the alarming stage. That's why I U. C. N. This species is declared the least risk. [1]
This species is preserved in Wildlife Act of Bangladesh. [3] There are approximately 1, 9 million fewer than 3 million duck poultry around the world. [5]
Male Nilshir (duck) head is shiny green and wings and stomach gray color. The wife has dyed body color, it has small brown drops. The Nilashir lake and its surroundings are grouped together. The main food of small animals and aquatic plants. Most of our poultry duck ancestors duck this nilishi [6]
Classification and expression
Jean James Aduv
In the eighteenth century, Carolus Linnaeus was his unforgettable Sistema Naturi
(Systema Naturae), which is the first of the two species named Biped, one of the Nilishi. The name given by Linnaeus is still as its scientific name. [7]
Nilshir's English name is Malard ("Mallard"). Perhaps the word is in Old French
Comes from malart or mallart (orange duck). In English, it is also called modelard ("maudelard" or "mawdelard"), which is related to the ancient High German model (Madelhart). [8]
Nilshi often grows with other close relatives of Anus mass; Such as American black duck. They are capable of breeding successfully with domestic ducks. In addition to closely related species (eg, langahans), they breed and produce hybrids and these hybrids can breed. [9] Generally, those born in the form of necrosis do not get reproductive. But there is an exception to Nilshir. Because the species evolving in the Pleistocene era has been able to complete its expression very quickly in less time.
In 2013, the genome sequence of Nilshir has been discovered. [10]
According to biogeography, Nilshi is more related to Indo-Pacific species than its close proximity to American species.
Through DNA analysis, it is assumed that their origin is probably the result
Siberia or its surroundings [11]
Local Meteheas and other American close relatives among Nilshir's members in the Bering Sea region
Typical genes have been detected. [12] The members of the Algerian Islands are living quite differently, because of them the gene diversity is less. As a result, the members of the group are a new one
Continuing to form sub-caste
[11]
Various variations of the physical shape of Nilshir are seen in position and sub-species.
Greenland duck is bigger than the southern duck, bastard botchtata and shorter lipstick. Sometimes they are considered as a separate species of Greenland Nilishi (A. p. conboschas).
Details
The male is blue in blue eyes
Darpan feathers
Although the mid-sized waterfowl of Nilshi is very heavy compared to most ducks. Its length is 50-65 cm (20-26 inches) (in which about two-thirds of the length of the body except the tail), the wings spread to 81-98 cm (32-39 inches), [13] and weights 0.72-1.58 Kg (1.6-3.5 feet).
[14] [15] The length of the wings is 25.7 to 30.6 cm (10.1 to 12.0 inches), the lips 4.4 to 6.1 cm (1.7 to 2.4 inches) and the leaves of the feet 4.1 to 4.8 cm (1.6 to 1.9 inches). [16]**
