Farmed birds that are fed with commercial bird food are typically given a pre-blended feed consisting largely of grain, protein, mineral, and vitamin supplements. Examples of commercial bird food for chickens include chick starter medicated crumbles, chick grower crumbles, egg layer mash, egg layer pellet, egg layer crumbles, egg producer pellets, and boiler maker med crumbles.

Some bird species undertake shorter migrations, travelling only as far as is required to avoid bad weather or obtain food. Irruptive species such as the boreal finches are one such group and can commonly be found at a location in one year and absent the next. This type of migration is normally associated with food availability. [179]
Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes).Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae or Galloanseres (initially termed Galloanseri) (Latin gallus ("rooster") + ānser ...
The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago, as do Egyptian hieroglyphics. Pigeons were most likely domesticated in the Mediterranean at least 2000–5000 years ago, and may have been domesticated earlier as a food source. [3]
The chicken (Gallus gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting.
However, blue jays have also been known to attack or kill other smaller birds, and foliage-roosting bat species such as Eastern red bats. [33] Jays are very territorial birds, and they will chase others from a feeder for an easier meal. Additionally, the blue jay may raid other birds' nests, stealing eggs, chicks, and nests.
The term also includes waterfowls of the family Anatidae (ducks and geese) but does not include wild birds hunted for food known as game or quarry. Recent genomic studies involving the four extant junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia.

Quail is a collective name for several genera of mid-sized birds generally placed in the order Galliformes. The collective noun for a group of quail is a flock, covey, [1] or bevy. [2] Old World quail are placed in the family Phasianidae, and New World quail are placed in the family Odontophoridae.
