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?
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.
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!
What is the scientific name for flightless birds?
The scientific name for flightless birds is ratites. This group includes birds like ostriches, emus, rheas, kiwis, and cassowaries. Ratites are characterized by their lack of keel on the sternum bone, which is necessary for flight muscle attachment.
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 are some large flightless birds?
ostritches rheas cassowarys emus
Are emus a type of elephant?

What is the name of the genus of large flightless birds which include the ostrich?

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!!
What kind of birds are ostriches?
Simple answer: They are large flightless birds native to Africa Technical answer: They belong to the order Struthioniformes along with kiwis and emus.
