Wild bird experts from NGOs in New Zealand were allowed to photograph these precious birds visiting North Korea.


Experts allowed to photograph wild birds with permission of the North Korean government. Furthermore, it seems that the security forces reported that we were watching birds.


According to Mr. Richard Fuller studying wild birds at the University of Australia, tidal flats, a place of relaxation for wild birds, are decreasing globally, and the area is reduced by a third compared to 50 years ago Thing. Wild birds have been driven to the remaining tidal flats, and wild birds have no choice but to change break spots and flight paths. In East Asia, the development progresses in Korea and China, the tidal flat is buried in the landfill and the case has disappeared, and wild birds that can not be rested in China and South Korea are gathered in North Korea.

Although it is a wild bird whose habitat is narrowed, the tidal flat in North Korea has no contamination of pesticides and pollution of rivers by factories, and that wild birds' abundance is abundant.


Residents of North Korea also showed interest in wild bird observation, said David Melvin, a member of the Wild Bird Expert Group.


While traveling abroad by travel restrictions is not free, it may be migratory birds to know North Korea more than humans.
