Canarian Oystercatcher - Description

Description

The Canarian Oystercatcher was of similar size as its relatives, the African and Eurasian Oystercatchers, or about 40–45 cm (around 16.5 in); comparing with the non-migratory African species, it probably weighed between 600-800 grams in life, with females being slightly heavier. Its bill was some 70-80mm long in males and markedly longer (around 80mm) in females; the tarsus measured around 50 mm, and the wings were around 250-265mm long, with males possibly at the upper range of that size (Bannerman 1963).

Its appearance was extremely similar to the African species, to the extent that even hand-held specimens can hardly be told apart except by direct comparison or measurements. Its bill was longer and its wings were shorter than in the African species, which is not known to occur north of Lobito, Angola however, at least in modern times. H. meadewaldoi had a glossy black coloration overall save for the whitish underwing bases of the primary remiges' inner webs, but this may have not been present in worn plumage which also was duller (Bannerman 1963). Its bill, laterally compressed and with a blunt, lighter tip, and a narrow naked ring around the red eye were reddish orange, and the legs and feet were dark pink with ivory-colored nails. As usual in oystercatchers, it had no hallux and the second and third toes were connected by a small web (Álamo Tavío 1975).

The sexes did not differ in color; juvenile birds are unknown but probably had duller bare parts and some greyish-buff fringes to the feathers. The coloration of downy young is likewise unknown; these are generally brownish-grey above with dark striping to provide camouflage against predators such as gulls (Hockey 1996); considering the dark lava rock habitat of this species, they were probably fairly dark overall and had a dusky belly.

Famous quotes containing the word description:

    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.
    Elaine Heffner (20th century)

    A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.
    John Locke (1632–1704)

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)
