Birds are very clever and very helpful. They have managed to make friends with larger animals without being attacked by providing a service for them. They remove ticks and other pests from the animal’s body and as they disturb the land.
Noone is sure how this partnerships started. How they communicated with these normal predators. But at sometime one brave bird flew up to a rhinos aurous and plucked a leach from its back and the friendship began.
Now these birds are welcomed on many animals, there are claims that some birds help crocodiles although these claims are not substantiated. Some help whales and elephants. The birds are welcomed and do a great job of freeing these animals of pests. The animal is relieved and more relaxed and it is easy food for the bird. Also it takes the risk out of hunting for prey in the normal way where the bird exposes itself to predators. If the bird feeds off an elephant it is protected for that meal and does not have to hunt and defend itself.
Therefore, these partnerships have evolved over the centuries and the animals and birds of this nature have formed strong and lasting bonds.
