It's heartening, in the midst of the human-caused sixth mass extinction, to find good wildlife recovery news. As plant and animal species disappear faster than they have for millions of years, Russia's Siberian, or Amur, tigers are making a comeback. After falling to a low of just a few dozen in the mid-20th century, the tigers now number around 500, with close to 100 cubs — thanks to conservation measures that include habitat restoration and an illegal hunting crackdown.
The last known female Yangtze giant softshell turtle (Rafetus swinhoei) has died, putting the critically endangered species at risk for extinction. There are now only three left in the world.
Update: The window for photo submissions has ended. The winner will be announced this Monday, April 22.
Earth Day is celebrated each year on April 22nd. The official theme of Earth Day 2019 is 'Protect Our Species.' In honor of Earth Day, EcoWatch has kicked off a second photo contest.

What are the most dangerous U.S. cities for migratory birds?
That's the question answered by a new study published last week in Frontiers in Ecology and the Environment, which looked at the problem of light pollution. Seventy percent of bird species present in the U.S. are migratory, and more than 80 percent of those species migrate at night. The increasing light pollution of cities attracts the avian travelers, who then crash into buildings. Building collisions kill an estimated 600 million birds in the U.S. every year, according to the Cornell Lab of Ornithology, which led the study.
The researchers created two lists for the cities that pose the greatest risk to birds during both the spring and fall migratory season, based on both geography and light pollution.
One of the most endangered wolves in the world is indeed its own species. That's the important finding of a National Academies of Sciences, Engineering and Medicine report released Thursday, which determined that red wolves are genetically distinct from gray wolves and coyotes.
