Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.
The three Western European Columba pigeons, common wood pigeon, stock dove and rock dove, though superficially alike, have very distinctive characteristics; the common wood pigeon may be identified at once by its larger size at 38–44.5 cm (15– 17 + 1 ⁄ 2 in) and weight 300–615 g (10 + 5 ⁄ 8 – 21 + 3 ⁄ 4 oz), and the white on its ...
Argote says it's about time pigeons get the hero treatment: " 'Dinosaur' is, like, a very serious proposition of what could be a monument that doesn't celebrate men, a war, a victory, but that ...
Unlike mammalian milk, which is an emulsion, pigeon crop milk consists of a suspension of protein-rich and fat-rich cells that proliferate and detach from the lining of the crop. [10] Pigeon's milk begins to be produced a couple of days before the eggs are due to hatch. The parents may cease to eat at this point in order to be able to provide ...
Pigeon chicks, approximately twenty days of age. In culinary terminology, squab is an immature domestic pigeon, typically under four weeks old, [1] or its meat. Some authors [who?] describe it as tasting like dark chicken. [2] The word "squab" probably comes from Scandinavia; the Swedish word skvabb means "loose, fat flesh". [3]
Rock pigeons are also acrobatic flyers-watch them zoom around a city park, or effortlessly fly between the pilings under a dock-these birds can give most predators a run for their money.

Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.
