More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. The Gray Crowned-Crane is a new addition to the list of the world’s Endangered species, creeping up a category from Vulnerable.

DECEMBER 11, 2018
Over two years (2011 and 2012), scientists captured 50 birds and successfully transported them from Niho to Laysan. No birds died during the translocation and the one-year survival rate was 58% in the 2011 and 96% in the 2012. The photos are from the USFWS Flickr album of the initial translocation in 2011. 2011): 265-272.
