The gaseous layers that surround the earth, is the Atmosphere, where oxygen, nitrogen, carbon dioxide and other gases are found.

Learning: White Naped Tit bird species is very patchily distributed and has been considered to be vulnerable to extinction especially because of the scarcity of suitable habitats particularly nest cavities made by woodpeckers. Two patches are: one in central and southern Rajasthan, Kutch and northern Gujarat in the north-west, and the other in the Eastern Ghats of southern Andhra Pradesh, northern Tamil Nadu and Karnataka in the south. It inhabits tropical, dry thorn-scrub forests, particularly those dominated by Acacia species, from the lowlands and foothills up to at least 750 m, occasionally straying into gardens, vegetated streambeds, and irrigated crop fields during drought years. The 21st Indian Birding Fair is happening at the Man Sagar Lake, Rajasthan and this year, this fair is dedicated to the White Naped Tit bird, which is quite rare in Jaipur and are at the verge of extinction.

In 2017, the Chiru goat species was assessed as ‘near threatened’ by the International Union for Conservation of Nature (IUCN) because their
the current population can only be maintained with continued high levels of protection in its natural range and strict controls on trade of the shawls
made from its underfur.
