Great Spotted Kiwi - Description

Description

Great Spotted Kiwis are the largest of the kiwis; the male is 45 cm (18 in) tall, while the female is 50 cm (20 in) tall. Bill length ranges from 9–12 cm (3.5–4.7 in), while weight ranges between 1.2 and 2.6 kg (2.6 and 5.7 lb) for males and 1.5 and 3.3 kg (3.3 and 7.3 lb) for females. The body is pear-shaped, while the head and neck is small with a long slender ivory bill. The Great Spotted Kiwi, along with the other Kiwi species, is the only bird with nostrils at the end of its bill. The eyes are small and do not see well, as it relies mostly on its sense of smell. The legs are short, with three toes per foot. It has a plumage composed of soft, hair-like feathers, which have no aftershafts. The plumage can range from charcoal gray to light brown. They have large vibrissae around the gape, and they have no tail, only a small pygostyle. The common name of this bird comes from black spots on its feathers. They use their powerful legs and claws for defense against predators like stoats or ferrets. Kiwis are flightless birds, and hence lack hollow bones, lack a keel to which wing muscles anchor, and have tiny wings. This species also has a low body temperature compared to other birds. Average lifespan is 30 to 40 years.

Famous quotes containing the word description:

    As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.
    Henry David Thoreau (1817–1862)

    The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.
    Guy Debord (b. 1931)

    Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.
    Ralph Waldo Emerson (1803–1882)
