Birds, also known as Aves, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5 cm bee hummingbird to the ostrich. They rank as the world’s most numerically-successful class of tetrapods, with approximately ten thousand living species, more than half of these being passerines, sometimes known as perching birds. Birds have which are more or less developed depending on the species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in flightless birds, including ratites, penguins, and diverse endemic island species of birds. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming.

Unfortunately, these Hawaiian geese are endangered; yet they are just so beautiful! I'm glad people are doing their best over there to protect these precious birds from further extinction ^_^

Scientists Teach Birds the Language of another Bird Species

When it comes to small birds who eavesdrop on other species, they easily pick up on words along the lines of "Danger!" Scientists at Australian National University designed an experiment with wild superb fairy-wrens to see if they could recognize previously unfamiliar alarm calls and most of them fled in response to the calls of fake predatory birds.

Killary, the Falcon

Earlier this year, I had the opportunity to go to the Falconry School in Ireland to fly falcons for the first time. Falcons are extremely intelligent birds and are hunting, predators by nature. This falcon is Killary.

Crow Hitches Ride on Eagle's Back

A lucky California-based bird photographer named Phoo Chan captured an amazing rare set of photos featuring a crow hitching a ride on an eagle's back. It landed and rode on the back of an eagle right in mid-flight! The eagle was searching for a snack in the skies of Seabeck, Washington when the crow spied an opportunity. This encounter was very brief, just a few seconds. Chan says, "I think the crow decided to land on the eagle because the eagle didn't respond to its harassment so it landed briefly and then left."
