Some larks have heavy bills (reaching an extreme in the thick-billed lark) for cracking seeds open, while others have long, down-curved bills, which are especially suitable for digging. [14] Larks are the only passerines that lose all their feathers in their first moult (in all species whose first moult is known). This may result from the poor ...
A fairly small lark, the crested lark is roughly the same size as a Eurasian skylark, but shorter overall and bulkier around the head and body, and very similar in appearance, [7] with a height of 17 cm (6.7 in) and a wingspan of 29 to 38 cm (11 to 15 in), weighing between 37 and 55 g (1.3 and 1.9 oz).

Bush larks are terrestrial and omnivorous foragers with a short, stout bill suited for crushing seeds. They eat mainly grass seeds and invertebrates, particularly insects during the breeding season. By gleaning and probing most food is taken from the ground surface or, just below. [4] Mostly they forage alone, but sometimes are found in small ...
The genus name is from the Latin alauda, "lark". Pliny thought the word was originally of Celtic origin. The specific arvensis is also Latin, and means "of the field". [4] The results of a molecular phylogenetic study of the lark family Alaudidae published in 2013 suggested that Eurasian skylark is most closely related to the Oriental skylark ...
Archived (PDF) from the original on 7 April 2014. The larch paradox—Finally, let us turn to one last, enduring ecological paradox: the deciduous habit of larches (Larix) at high latitudes in nutrient-poor peatlands in the northern hemisphere, where evergreen plants are expected to dominate and often do. Quote from p. 729.
Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere. They feed on seeds, fruit, and plants. Unlike most other birds, the doves and pigeons produce "crop milk", which is secreted by a sloughing of fluid-filled cells from the lining of the crop. Both sexes produce this highly nutritious substance ...
The Mongolian short-toed lark was formerly considered as a subspecies of the greater short-toed lark (as C. b. dukhunensis) until split in 2016 by the IOC. [6] Formerly, some authorities also considered the red-capped lark to be either conspecific (as C. cinerea) with or a subspecies (as C. b. cinerea) of the greater short-toed lark. [7]
The desert lark is a medium-sized, big-headed and long-billed lark, growing to a length of 16 to 17 cm (6.3 to 6.7 in). The sexes are alike, but there is considerable geographical variation. It has a rather dull plumage which can vary from quite pale to rather dark.
