Birds 'falling out of the sky' in mass die-off in south-western US


Thousands of migrating birds have inexplicably died in south-western US in what ornithologists have described as a national tragedy that is likely to be related to the climate crisis.

Flycatchers, swallows and warblers are among the species “falling out of the sky” as part of a mass die-off across New Mexico, Colorado, Texas, Arizona and farther north into Nebraska, with growing concerns there could be hundreds of thousands dead already, said Martha Desmond, a professor in the biology department at New Mexico State University (NMSU).

Computer algorithm spots endangered wildlife in satellite images


Satellites have offered scientists a powerful new tool when it comes to tracking endangered wildlife, with the movements of tagged animals able to be monitored with great precision. A new technology promises to expand the possibilities even further, with scientists demonstrating a new computer algorithm that can be used to track untagged animals in complex landscapes via satellite imagery for the first time.

California banned indiscriminate fishing nets.
Now these porpoises are on the rebound


In California, decades of commercial sea bass and halibut fishing killed thousands of other coastal animals. Outraged by the deaths of sea otters and diving seabirds, voters in the state banned many of the nets from near-coastal waters starting in 1994.

Lower-profile marine mammals have also benefited. New research shows that getting rid of gill nets gave California's harbor porpoises — one of the smallest toothed whales — a chance to rebound.

Shark and ray populations have plummeted by 71% in half a century


Scientists looking at shark and ray populations across the globe have published an alarming study depicting a rapid decline of these species over the past half century. This spells trouble not just for those animals in particular, but the ripple effect it would have on the ocean ecosystem as a whole, with the authors laying the blame mostly at the feet of unsustainable fishing practices.

I have always emphasized the significance of satellites for monitoring wildlife. I suppose scientists need to devote more attention to it and equip all environmental satellites with high-resolution imagery, especially since even young space companies like https://dragonflyaerospace.com/ manufacture high-resolution optical imagery for microsatellites, CubeSats and smallsats. Why don't they cooperate with any satellite manufacturer and launch more environmental satellites? I know that all space companies are now focused on exploring other planets, but they shouldn't forget about Earth too.

Which animals will survive climate change?


Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers from McGill University show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes. Their findings could help scientists forecast the evolutionary future of these populations.

8 Animals That Are No Longer Endangered


In September 2016, after almost 50 years of managed breeding and conservation efforts, the giant panda was upgraded from "endangered" to "vulnerable" on the IUCN red list. Now, there are between 1800 and 2050 giant pandas in the world, and the number is increasing.

It’s not the first time a species has been dragged back from the brink. Here are eight other animals that have made a comeback—with help from conservation laws and dedicated scientists.
