Development of the Keel in Different Birds

The keel, also known as the carina, is a large, flat projection of the sternum bone in birds to which the flight muscles are attached. It is particularly well-developed in birds that are strong fliers. Let's explore the development of the keel in different birds.

1. Peacock

The keel in peacocks is relatively small compared to other birds. As peacocks are not known for their strong flying abilities, their keel is not as prominent as in birds that are strong fliers.

2. Ostrich

Ostriches, being flightless birds, have a very small and rudimentary keel. Their keel is not developed for flight but rather for the attachment of powerful leg muscles.

3. Chicken

Chickens, like peacocks, have a relatively small keel. They are not strong fliers and therefore do not require a large keel for flight muscles.

4. Lark

Larks, being small songbirds, have a well-developed keel. Their keel is relatively larger compared to peacocks and chickens, as they are known for their strong flying abilities.

It's important to note that the development of the keel is closely related to the bird's flying capabilities and the need for strong flight muscles.
