Newell's Shearwater - Description

Description

It is a fairly small shearwater, 33 centimetres (13 in) in length. The wing is 223–249 millimetres (8.8–9.8 in) long and the tail is 78.9–88.8 millimetres (3.11–3.50 in). The bird weighs 0.340–0.425 kilogram (0.75–0.94 lb). The upperparts are black with a brown tinge while the underparts are white. The dark coloration on the face extends below the eye and is sharply separated from the white throat. There is a white patch on the flanks, extending onto the sides of the rump. The underwings are mainly white with a dark border. The undertail-coverts have a black and white pattern and appear white in the field. The bill is dark grey or brown and the legs and feet are mainly pale pink. The bird flies low over the water on stiff wings with a mixture of short glides and periods of rapid flapping. It utters a donkey-like braying call around the breeding areas. Townsend's Shearwater (P. auricularis) is very similar but has dark undertail-coverts, a shorter tail and a less sharp boundary between the black and white on the face.

    An intentional object is given by a word or a phrase which gives a description under which.
    Gertrude Elizabeth Margaret Anscombe (b. 1919)

    Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.
