One of the most special features of the pigeon is their unusual homing instinct.
Yes, as do most animals.
Yes, it's called instinct. Most animals have the fight or flight instinct. Horses are a good example of this.
Most animals do. They have instinct about what to do. Also, their mothers normally help them.
Mammals
Doves make good pets because they are easy to care for and a lot of people love the cooing sounds they make. On the other side there are a lot of dove releases at weddings and functions, not many people know that most of those birds that are released die shortly after. Doves do NOT have a homing instinct, meaning they fly back home after they are released. Only homing pigeons have that instinct
The homing is the largest pigeons owned by people all over the world.
Most likely just to wild animals. It's just instinct and most dogs do it. Even the sweetest dogs in the world, in my experience.
the most popular is probably a horse! :)
Yes it appears that dogs are the most popular animals.
Most animals can't. Some animals have an instinct, though, that can hear even the slightest snowflake drop. So, it depends on what animal you are referring to.
