Can birds get electrocuted if they come in contact with two wires?

Yes, a bird can get electrocuted if it comes in contact with two bare power lines. The power lines are spaced apart so only the largest birds (buzzards, eagles, etc.) would be able to touch two at the same time.

Why is it essential to earth electrical appliances having metallic body?
if the appliance shorts out (if one or more of the wires inside it come into contact with the outer casing) the electricity will take the shortest route to be neutralised. If there is no earth wire and you touch the shorted out appliance then the shortest route to neutralise the electric charge is through you, and you will be electrocuted. If an earth wire is present then the shortest route to neutralise the current will be through this wire, so you would not be electrocuted if you touched the shorted out appliance.
Microwelds are formed where?
bumps from two surfaces come into contact.
Where does an earthquake originate?
they come from angry writting desks that are mocking birds
What process forms hornfels?
Hornfels is formed when mudstone or shale come in contact with a hot igneous body and metamorphic rock. This process is called contact metamorphism.
What kind of bond is eventually formed when a potassium atom and a fluorine atom come into contact?
An Ionic Bond.
How come birds can land on power lines without being electrocuted?
The high voltage is between one wire and the other. From one point on the wire to another point on the same wire, the voltage is quite insignificant. As long as the birds don't touch both wires, nothing much will happen. The wire does not have a difference in voltage from foot to foot. The term "high voltage" refers from wire to ground. Electricity flows down a voltage gradient. There is no gradient of voltage between the feet.
How come birds on electric wires dont get electrocuted?
For an electric current to pass through the bird's body, there must be a potential difference (voltage) across its legs. But its legs are connected to a very good conductor which means that the bird's legs must be at the same potential -no potential difference, no shock!

Why do birds not get electrocuted when they sit on the third rail?
In order for someone to be electrocuted by a live power line or 3rd rail on the train they must also be in contact with ground, or close enough for the power to jump to ground on it's own. That is also why they can sit on a power wire, the insulators at the poles keep the power from reaching ground. High voltage transmission lines can be repaired by a helicopter crew. There is a strict procedure to follow though. The helicopter hovers close to the wire and a ground between the helicopter and the wire is established by making contact with the wire through a high voltage probe. Once that occurs, the operator hooks a clamp to the wire for a permanent connection. At this point, the operator can touch the wire and repair it without getting shocked. When done, the reverse procedure is followed exactly.
How come birds on electric wires dont get electroucuted?
They are not grounded. Electricity is going to take the shortest route possible and with the least resistance...therefore it is "easier" for the electricity to travel in a straight line through the metal cables than to travel up and back down again through a bird which is not conductive. If you were to hang from a power line (assuming you didnt come close to another one) you would not be electricuted, only if you touch the ground or another wire or pole will you get zapped.Answer The resistance of the wire between the bird's feet is so low that the current passing through the conductor cannot create sufficient voltage drop to harm the bird. Should part of the bird come into contact with another line conductor, or an earthed conductor, then it will be killed.
Why do birds not electrocuted when they are staying on live wire or wires?
Power lines are insulated and as long as they don't touch the ground (or another object) they won't be electrocuted.AnswerMost power lines are not, in fact, insulated because they are already surrounded by an insulating media -air.The reason that birds don't get electrocuted is because each foot is at the same potential and, for current to flow (it's the current which causes electrocution) through its body, each foot must be at a different potential. The bird is safe, providing another part of its body doesn't come in contact with one of the other conductors.
Where does penguin birds come from?
They come the same way all other birds come from. An egg.
Is newpaper ink toxic to birds?
Well this really depends on how you suppose the Birds come into contact with it... If the bird is drinking it then it's more poisionous than toxic... but if you say that the bird is inhaling the air which has been near a newspaper, i am almost definite that the birds would be unharmed...

How does Mr twit catch the birds in the twits?
Mr. Twit catches birds by smearing sticky glue all over the branches of the tree where the Roly-Poly Bird sits. The birds get stuck to the glue when they come in contact with it, allowing Mr. Twit to collect them for his bird pie.
Does a blue crab have poison ivy?
No, they cannot come in contact with the plant in the first place, and, they would not be affected by the toxins because it mainly affects mammals or birds.
