Bui Duc Tien, an ornithologist who is also a photographer, has taken thousands of photos of bird species in Vietnam.
Following photos are about dozens of rare birds captured in some destinations in Ninh Binh province.
The appearance of diverse species of birds in the province has proved the endless effort of Ninh Binh in protecting the environment and biodiversity over the past few years.
We need to join hand to build Ninh Binh as an attractive destination and a paradise for species of birds to habitat.
