Description
It is distinguished from Hume's and Lesser Whitethroats by its smaller size (12 cm length, 8–13 g weight), smaller bill, the uniformly paler grey head lacking the well-marked dark cheeks of Hume's and Lesser Whitethroats, and a lighter grey-brown back; in these differences it follows Gloger's rule of pale colour in arid regions. The throat is white, and the rest of the underparts pale greyish-white.

Famous quotes containing the word description:
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“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)
“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)
