What are the characteristics of flightless birds?
Flightless birds have a small keel and wings.
Why do most flightless birds not need a large keel?
They do not need to flap their wings.
What do flightless birds have in common?
they can't fly, they are large and they have no wings, obviously! flightless birds include: ostrich, cassowary, emu and penguins!
Do penguins come under ratites?
I do not think so, as ratites have no keel and have a flat sternum. Ostriches are an example of this large flightless bird that could not fly even if it had large enough wings. No keel to anchor the flight muscles.
What muscle is attached to the keel of a bird?
A keel or carina in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Keels do not exist on all birds; in particular, some flightless birds lack a keel structure.Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two classes:Carinatae (from carina, "keel"), having a pronounced keel; and ratites (from ratis, "raft" - referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely. However, this classification has fallen into disuse as studies have shown that many flightless birds have grown (from GOD) from flighted birds. The current definition of Carinatae now includes all extant birds.Does that help you? Tell me if it does. Thanks Everyone! God Bless!!
