Bar-tailed godwit 
(Choắt mỏ thẳng đuôi vằn, Limosa lapponica)

The bar-tailed godwit (Limosa lapponica) is a large and strongly migratory wader in the family Scolopacidae.

The bird breeds on Arctic coasts and tundra from Scandinavia to Alaska, and winters on coasts in temperate and tropical regions of Australia and New Zealand. The migration routes includes: those breeding in Alaska across the Pacific Ocean to New Zealand; those breeding in Siberia along the coasts of Asia.

The bird is commonly found at the Giao Thuy National Park during the winter time.

The godwits can be distinguished from the curlews by their straight or slightly upturned bills, and from the dowitchers by their longer legs. 
The genus name Limosa is from Latin and means "muddy", from limus, "mud". The English name "godwit" is believed to imitate the bird's call.
The specific name lapponica refers to Lapland, "Laponia".
