Answer 1

It's an adaptation which helps them catch/eat the kind of food they live on.
Ex: Flamingos use their long necks to put their heads into the water and skim out food while wading in the lake/water.

Answer 2

There are alot of reasons. Depends on what they eat where they live ect. Swans eat offthe bottom of a lake . weeds & roots. Sand Hill Crans have very long necks also. They have great eye site. & can pluck a fish out of the water deep or shallow. They have really long legs so they can just wade & be still in shallow water untill there pray swims by then with long neck fish head 1st, down the hach it gose . you can see the hole fish slide down the birds neck.

Answer 3

everyone else is wrong
The reason for long necks on some birds are because of the many years of trial and error in genetic makeup resulting in a mutation that was helpful due to other birds without the mutation did not survive passing the trait to future generations

Answer 4

that's an stunning blue heron, the consume fish and frogs and hunt interior the water with their long neck and beak some situations they hide in tall grass so the fish do not see there shadow on the water.

Answer 5

because God designed them that way....let us pray


actually....because they are the descendants of birds who were successful in competing for limited resources and their offspring inherited their advantageous characteristics (fit traits)

...their long necks (simple variation among individuals--surely some were better runners or had better eyesight) happened to give them a selected advantage in competing for limited resources....perhaps finding or reaching food and better able to see danger.....and they in turn were more likely to survive and more likely to reproduce

Answer 6

So they can reach food that is at the bottom of a river or deep down in long grass etc.

Answer 7

So they can stick their head into holes in trees and the ground to get bugs and insects to eat

Answer 8

most of the time they are good for water for eating fish diving under the water

Answer 9

because they are born like that.
