Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.
The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.

His Holiness Sri Ganapathy Sachchidananda Swamiji's deep concern for the preservation of our environment has manifested itself in Avadhoota Datta Peetham, Mysore as Kishkindha Moolika Bonsai Garden, Ashwashala (Horse stables), Goshala (Cow shelters) and Shuka Vana (rehabilitation centre for birds). Parrots are not just agreeable birds with their chirping sounds and attractive, vivid colors. Parrots have a specific spiritual connection with the nine planets (Navagrahas), the twelve zodiac signs (Rasis related to birth stars), the numerals of the dates in each month, and the seven musical notes Sa, Ri, Ga, Ma, Pa, Da, Ni (Saptaswaras) in Indian classical music. With divine intuition, Sri Swamiji has identified sets of species of parrots that represent each of the above as its vibrant, livi...
Parrots: Majestic Birds (Nature Documentary) NATURE tracks down the cockiest characters in the land down under in Parrots in the Land of Oz. We keep them in cages in our homes, but in their natural state they are independent birds who can seek out water over hundreds of miles through pure instinct. We feed them seed from a pet store, but they can find food in a wide variety of habitats. We give them plastic toys and mirrors to play with when in fact in the wild some have figured out how to use tools to communicate and attract mates. For tens of millions of years, parrots have survived and thrived in Australia even as the continent underwent dramatic changes, including some brought about by man. Though some, like the golden-shouldered Parrot are threatened, these tough Aussies have adapt...

Ospreys are the only birds of prey that rely almost entirely on fish, so they nest and raise their chicks near water. They return to Hog Island each year in early April after wintering in South America. The Hog Island ospreys laid the first of their three eggs on April 26, and incubation time is 35-42 days. The female (recognized by the heavy striped pattern on her breast) does most of the incubation and the male often feeds her at the nest. After the eggs hatch, the parents brood the chicks, protecting them from extreme weather and predators. They are very diligent parents, never l...

This video is a compilation of some of the many short bird videos that I have filmed while taking pictures in the New World Tropics. I hope that you enjoy it. The first 6 minutes or so is simply the audio from the field. Many of the clips I had did not have usable audio so instead I asked a friend if I could use some of her beautiful music to go with the video. If you enjoy her music please visit her website at - http://www.jessicabenini.com/ Cheers everyone! Glenn

Birds, they're walking all around
Birds, they're making little sounds
Have you seen any birds today
I will blow those birds away

Rocks and stones make a worm complete
Worms, worms, worms, worms
Birds, they're looking pretty cute
Birds, I see 'em, I shoot
Have you seen any birds today
I will blow those birds away
