Bird

Birds (class Aves) are feathered, winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. With around 10,000 living species, they are the most speciose class of tetrapod vertebrates. All present species belong to the subclass Neornithes, and inhabit ecosystems across the globe, from the Arctic to the Antarctic. Extant birds range in size from the 5 cm (2 in) Bee Hummingbird to the 2.75 m (9 ft) Ostrich. The fossil record indicates that birds emerged within theropod dinosaurs during the Jurassic period, around 160 million years (Ma) ago. Paleontologists regard birds as the only clade of dinosaurs to have survived the Cretaceous–Paleogene extinction event 65.5 Ma (million years) ago.

Famous quotes containing the word bird:

    Here and there a bird sang, a rose silenced her expression of him, and all the gaga flowers wondered. But they puzzled the wanderer with their vague wearinesses.
    John Ashbery (b. 1927)

    The bird is lost,
    Dead, with all the music:
    While sunsets heard the brain’s music
    Faded to last horizon notes.
    Owen Dodson (b. 1914)

    The caged bird sings
    with a fearful trill
    of things unknown
    but longed for still
    and his tune is heard
    on the distant hill
    for the caged bird
    sings of freedom.
    Maya Angelou (b. 1928)
