The falcated duck or falcated teal (Mareca falcata) is a gadwall-sized dabbling duck. Falcated ducks have a very intricate courtship ritual. Females perform a series of inciting calls and other movements while preening behind the wings of their targeted male. Males use a courting method similar to others in the Anas genus, including an introductory shake, a neck-stretching burp call, a grunt whistle, and a head-up-tail-up display. During the mating season the falcated ducks form monogamous pairs that last throughout the mating season.[3] It is not known how long the falcated duck lifespan is. There is also not much information on their territory size because these ducks are not studied as closely as other more popular species like swans or geese. The falcated duck breeds in eastern Asia. It nests in eastern Russia, in Khabarovsk, Primorskiy, Amur, Chita, Buryatia, Irkutsk, Tuva, eastern Krasnoyarsk, south central Sakha Sakhalin, extreme northeastern North Korea and northern China, in northeastern Inner Mongolia, and northern Heilongjiang, and in northern Japan, Hokkaidō, Aomori, and the Kuril Islands.[5] It is widely recorded well outside its normal range, but the popularity of this beautiful duck in captivity clouds the origins of these extralimital birds. It is estimated that there are about 89,000 falcated ducks in total; this is much higher than the previous population estimate of 35,000 worldwide. During a survey done in Central China, a migratory area in the winter for the falcated duck, the numbers of animals sighted was minimal. In 2004 only 4 were recorded, and in 2005 only 10. In Pakistan it can appear on Fresh Water Lakes and Large Rivers. No recent record, about five records up til the 1920s from Pakistan Region.
