There has been a study done and in over 60 years, there has never been a reported case of an ostrich burying its head in the sand.\n\nPure myth

Birds. Just to fly they'd need more brain power.

He doesn't.  And peahens don't either.  Like all birds, they lay eggs.

Moths don't like tea. They prefer Ovaltine.\n\nMoths have powder coating on their wings without which they would not be able to fly. If he'd been in the tea, he would not be able to fly, because the hot water would wash it off.. So check he's not running around on the floor or lying face up on your monitor.

... Birds can't jump? So, 6?

That is quite a difficult question to answer as you would have to know how many calories are in a particular food item (which can be determined using a calometry bomb) and how many calories are expended during flight. I would say that no, a pigeon would need more than a few grams of seed to fly kilometers (it also depends on how many kilometers were taking, 2 vs 100 is a huge difference). Many birds migrate overlong distances, but make stops to refuel and take adventage of flight formation (the V of geeese), wind currents, updrafts and anything else they can to make it easier so they really arent technically flying the entire distance, they glide a great majority of it. Although, knowing that they are going to be going a long way, birds do eat and store quite a bit to fuel them. \nWings and the tail provide steering, but its primarily the wings. \nSo, no a single meal is not enough, but yes the do consume enough calories to fly great distances.

Because they do not have a gastrointestinal tract like higher animals do.

It can't roll anywhere because rooster's can't lay eggs. If u meant rooster instead of roster.

i didnt know chickens could fly.

Mamals (teradactyles) used to fly with leatherlike wings so it would seem that humans could also.  However human arm and chest muscles are not very suitable for flight.  As in the term pigeon or chicken breasted, birds have muscular chests that fascilitate a powerful downward pull on the wings.  Coonsider the shape of a turkey breast and the thick breastmeat there.  Still, the only way a turkey can soar with the eagles, is in their talons.  We would tire too easily, even with very light fake wings.

If it has wings it's a "fly"\nIf it doesn't it's  "grounded"!!! \nThat was a cute question. I'd never thought of that....LOL ;o)

It was a swallow....\n\n\nArthur: The swallow may fly south with the sun or the house martin or the plover may seek warmer climes in winter, yet these are not strangers to our land? \nSoldier #1: Are you suggesting coconuts migrate? \nArthur: Not at all. They could be carried. \nSoldier #1: What? A swallow carrying a coconut? \nArthur: It could grip it by the husk! \nSoldier #1: It's not a question of where he grips it! It's a simple question of weight ratios! A five ounce bird could not carry a one pound coconut. \nArthur: Well, it doesn't matter. Will you go and tell your master that Arthur from the Court of Camelot is here? \nSoldier #1: Listen. In order to maintain air-speed velocity, a swallow needs to beat its wings forty-three times every second, right? \nArthur: Please! \nSoldier #1: Am I right? \nArthur: I'm not interested! \nSoldier #2: It could be carried by an African swallow! \nSoldier #1: Oh, yeah, an African swallow maybe, but not a European swallow. That's my point. \nSoldier #2: Oh, yeah, I agree with that. \nArthur: Will you ask your master if he wants to join my court at Camelot?! \nSoldier #1: But then of course a-- African swallows are non-migratory. \nSoldier #2: Oh, yeah... \nSoldier #1: So, they couldn't bring a coconut back anyway... \n[clop clop clop]\nSoldier #2: Wait a minute! Supposing two swallows carried it together? \nSoldier #1: No, they'd have to have it on a line. \nSoldier #2: Well, simple! They'd just use a strand of creeper! \nSoldier #1: What, held under the dorsal guiding feathers? \nSoldier #2: Well, why not?
