Birdwatching in Bhutan has been attracted by all over the world.

Over the years the kingdom has been attracting more and more birders, with most of the trips arriving in the spring from March through May when the bird migration is at its peaks. Although the number of species one may encounter is the greatest in the spring season, birding in the early winter months- when there are fewer birders and hence less competition for limited campsites along the birding circuits- can still be very rewarding for the bird seeker.

For example, the black-necked cranes would have migrated to its summer habitat in the Tibet by the mid-March, while it is a guaranteed sisgting from late October to mid-March. The white-bellied heron,one of the 50 rarest birds in the world,is more likely to be seen in the winter months than in the spring when it is nesting and rearing its young. Other much sought-after birds like the Ward's Trogon, Rufus-necked Hornbill and the Beautiful Nuthatch are residents and can be seen throughout the year.
