The mass of the closed system (bird and box) is 12 ounces no matter what.  However, the measurement of the weight will vary depending on the acceleration of the bird.  If the bird is resting, or flying in a stationary position, the weight will be 12 ounces.  If the bird stops flapping it's wings (free-fall) the weight will appear to drop.  If the bird is rising, the weight would appear to increase.

a bird, because it would be awesome to fly!!

The smallest hummingbird species in the world is the Cuban Bee Hummingbird, Mellisuga helenae, and it measures 5-6 cm in length (2.0-2.4 inches) and weighs a mere 1.6-1.9 grams (roughly 3/4 of an ounce). Most species, however, are larger:  in the U.S., most species are 3.0 - 3.5 inches in  length.

A box. You just don't know what's inside yet.

Humming bird necter is red. It attracts them better than other colors. I guess it mimics flower colors.

This is sybil's first question. Try and give her a good answer.\nI'm sure someone out there has a good idea of what it could be.\nAnybody got a bird book? Cause now I really want to know too.

Ruby-throated Hummingbirds do not hibernate, but others do

Whats nice about the world is that if a hummingbird dies, generally, another will replace it, and so the cirle of life goes on.  Unless you plan on tagging the hummingbirds for surveillance / observation, I dont think you'll notice any missing hummingbirds.

Heh.\n\nBird's poop is watery. All of their liquid waste gets mixed in with the poop.

The hummingbird will start moving backwards because the plane is accelerating and unless the bird is moving forward, the bird's inertia will have it attempting to stay in place which is moving backwards.\n\nBut if you're talking about a non-accelerating plane that is moving at a constant velocity then the bird will stay in place.

A bee hummingbird. It is the smallest in the hummingbird family.

Hacksaw, here's your answer...their WEIGHT is the same, but their DENSITY is quite different. A pound of gold has a higher density than a pound of feahers. when a pound of gold and a pound of feathers are placed into a tank of water...which has a density of 1, the gold wil sink faster than the feathers, due to the gold's higher density.

I don't think that it is possible to fit that many parakeets into one trailer of that size. Assuming that each parakeet weighs one ounce and 16 ounces make a pound 10,000 / 16 = 625 that means that 312.5 parakeets have to be flying at the same time. Not feasible, but all that aside would have to say that the birds that are flying still weigh the trailer down. Because:\n\na. Air has mass and therefore contributes the the weight in the trailer.\n\nb. Movement displaces air which creates pressure that pressure creates more weight.\n\nc. There are still 10,000 pounds of parakeets in the trailer.\n\nBut I could be wrong.

Because they are fowl
