"Persistence and determination alone are omnipotent!"

The mirror test is an experiment developed in 1970 by psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability to recognize itself in a mirror. It is the primary indicator of self-awareness in non-human animals and marks entrance to the mirror stage by human children in developmental psychology. Animals that pass the mirror test are: Humans older than 18 mo, Chimpanzees, Bonobos, Orangutans, Gorillas, Bottlenose Dolphins, Orcas (Killer Whales), Elephants, and European Magpies. Others showing signs of self-awareness are Pigs, some Gibbons, Rhesus Macaques, Capuchin Monkeys, some Corvids (Crows & Ravens) and Pigeons w/training. (Sorry Kitty!)

Magic in the Air

These tiny marvels dazzle and delight.

Hummingbirds take extraordinary to a whole new level. They are the smallest warm-blooded creatures on the planet, but they are also among the fastest. With wings that beat up to 200 times per second, they are among nature's most accomplished athletes, the only birds that hover, fly backwards, and even upside down.

Because hummingbirds live their lives in fast-forward, much of their fascinating world is typically lost to human perception. But using cameras able to capture over 500 images a second, the hummingbirds' magical world can finally be seen and appreciated. Amazing footage shows these little powerhouses are far more than delicate nectar gatherers - they are also deadly predators. And watch the birds display their elaborate mating rituals, showing off with nose dives that subject them to over ten G's of force - enough to cause an experienced fighter pilot to black out.

They tiny marvels dazzle and delight bird watchers all over the world, and Nature reveals their stunning abilities as they have never been seen before. Academy Award-winner F. Murray Abraham narrates.

2-8-18 Trove of hummingbird flight data reveals secrets of nimble flying
Trove of hummingbird flight data reveals secrets of nimble flying. Lab-grade flight tracking has gone wild, creating a broad new way of studying some of the flashiest of natural acrobats, wild hummingbirds. One of the findings: Bigger hummingbird species don’t seem handicapped by their size when it comes to agility. A battleship may not be as maneuverable as a kayak, but in a study of 25 species, larger hummingbirds outdid smaller species at revving or braking while turning. Measurements revealed these species have more muscle capacity and their wings tended to be proportionately larger for their body size than smaller species. Those boosts could help explain how these species could be so agile despite their size, researchers report in the Feb. 9 Science. Adapting a high-speed camera array and real-time tracking software to perform in field conditions let the researchers analyze more than 200 wild birds swerving and pivoting naturally. With over 330,000 bird maneuvers recorded, the researchers could compare the agility of the different species. It’s the first comparative study of natural flight moves in wild birds, says coauthor Roslyn Dakin, who is based in Ottawa with the Smithsonian Conservation Biology Institute.
