Description
The wild Atlantic Canary can range from 10 to 14 cm (3.9 to 5.5 in) in length, with a wingspan of 20 to 23 cm (7.9 to 9.1 in) and a weight of 8.4 to 24.3 g (0.30 to 0.86 oz), with an average of around 15 g (0.53 oz). The male has a largely yellow-green head and underparts with a yellower forehead, face and supercilium. The lower belly and undertail-coverts are whitish and there are some dark streaks on the sides. The upperparts are grey-green with dark streaks and the rump is dull yellow. The female is similar to the male but duller with a greyer head and breast and less yellow underparts. Juvenile birds are largely brown with dark streaks.
It is about 10% larger, longer and less contrasted than its relative the serin, and has more grey and brown in its plumage and relatively shorter wings.
The song is a silvery twittering similar to the songs of the serin and citril finch.
The hibridization with White-Rumped Seedeater has been obtained by Antonio Arnaiz-Villena et al.

Famous quotes containing the word description:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“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)
“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
—Henry David Thoreau (1817–1862)
