Why can't ostriches fly. They are ground birds?

Answer 1

Ostriches can't fly because they have tiny (vestigial) wings. Orstriches are large birds, and weigh quite a bit - and therefore would need HUGE wings in order to fly. For example, the California condor weighs on average between 16-20 pounds, and needs a wingspan of 10 feet in order to fly! This is the largest flying bird in North America. The Andean Condor is only slightly larger, and I believe is the largest flying bird in the world. There is a point where the weight of the body and the need for longer/bigger wings is not advantageous for a species. The ostrich is way beyond that metaphorical cut-off point. Hope this explains your question!

Answer 2

There is a possibility because the ostrich is the biggest bird on the world and the ostrich lay the biggest egg ever and they have a really long legs.

Answer 3

Hi:

The answer is the following:

Their wings are too small for their body size to allow for flight and their large legs also make them too heavy to fly. and yes they are gound birds However they can ran fast and they can kick with those legs plus add that with their beak which they can peck something with, they can inflect a great deal of hurt to any animal or person dumb enough to bother them .

The Penquins of the south pole are gound birds also they may not fly but with fly thru water like birds do in the air do.

Do read about them in wikipedia website or yahoo.

Hope this helps

a million, You did no longer ask a query, you in basic terms sanctimoniously preached, it incredibly is ironic for an antitheist (in spite of the reality that regrettably no longer uncommon). 2. the documents you gave is from the technology of evolution, and the small print of it incredibly is inhabitants genetics. inhabitants genetics replaced right into a medical container which replaced into effectively pioneered by capacity of S. B. Haldane, a mystic who believed in metaphysics and god, so the undeniable fact that Christians (or theists) do no longer or can no longer have faith in evolution is previous stupid. 3. Even all that aside you're flat out incorrect. in case you will lecture people on evolution it would make it easier to to incredibly know a few thing approximately it first, lest you appear to be an entire fool. the two birds and feathers progressed previously flying birds. The protoaves have been certainly flightless (a transition of dinosaurian and avian creatures). Feathers, needless to say, progressed in those dinosaurians previously that they had progressed to develop into birds, and as a factor of activity some birds rather reverted returned and grew to develop into dinosaurs later. Dinosaurs on no account went extinct, they only replaced their feathers.
