The list of endangered birds includes Great Siberian Crane, Indian Bustard, White backed Vulture and Red-headed Vulture, Forest Owlet, Spoon Billed Sandpiper,White Bellied Heron etc. The main reasons behind the decline in the population of these birds include loss, modification, fragmentation and degradation of habitat, environmental contaminants, poaching and land use changes.
The Siberian crane (Leucogeranus leucogeranus), are also known as the Siberian white crane or the snow crane. Siberian crane are nearly all snowy white, except for their black primary feathers that are visible in flight and with two breeding populations in the Arctic tundra of western and eastern Russia.

Their current status is “vulnerable.” The male wild Yak can weigh up to 2200 pounds and is 6.5 feet high at the shoulder.

Today its number decreased to less than 60 thousand (2012).This is the fastest disappearance of any bird species in the world, including Dodo. As we know that vulture plays a prominent role in the sanitation work. The disappearance of vulture has resulted in the explosion of rats etc. This degradation cost around US $ 25 bn. up to 2015.
