Large keel helps in attachment of large flight muscles pectoralis major .
if it is their own kind and a different gender, they do it to breed, otherwise to mob other birds in large groups or to get them away from their nest.
Flightless birds do not need a large keel because they don't have functional wings for flight, so there is no need for the large breastbone attachment needed for flight muscles. The keel is an adaptation found in birds that use their wings for sustained flight.
Birds may avoid animals with large eyes because they could be perceived as potential predators or threats. The presence of large eyes might signal alertness or aggressiveness, leading birds to view them as a potential danger. Additionally, birds may have evolved to avoid animals with large eyes as a survival strategy to reduce the risk of being attacked or eaten.
Large numbers of captive birds are typically kept in places such as aviaries, bird sanctuaries, zoos, or wildlife rehabilitation centers. These facilities provide suitable habitats and care for the birds, with the ultimate goal of promoting their well-being and conservation.
The function of the liver is the remove toxins and metabolic wastes from the body. Fetal pigs have large livers because this function is important early on in life.
Birds have there forelimbs modified into wings to fly. The chest muscles has to be very much stronger in birds to enable them to fly. To bear the force of flying, the sternum in birds has be relatively large as compared to human being.
its the sternum.
its the sternum.
The Western countries produce the large quantity of Sternum.
Mostly to impress female birds. ------------------------------------------------------ Above is BS because even female birds have large breast/chest muscles. Male coloring (plumage) is partly to attract a mate and partly to provide distraction to keep predators from the nest. In order to fly birds must have a broad chest with large breast muscles to pull forcefully on the wings.
The large medial area of the chest is called the sternum. It is a flat bone located in the center of the chest and connects to the ribs. The sternum plays a crucial role in protecting the heart and lungs.
I guess one could think of the sternum as the "backbone" that holds the ribs together, keeps them in place. The sternum and ribs are a cage like system that protects your heart and lungs from injury. Your ribs are also contected to your spine. Imagine not having any rib cage at all!
The sternum is a large bone just under the neck. It is long and very fragile
Some large birds are herbivores while others are not. Some large birds like flamingos dine on a diet of shrimp.
Large birds such as, Vultures, Eagles, and other large birds eat them.
Ostriches
Some birds, like falcons, eat smaller birds, but large birds who aren't birds of prey don't
