What do you think is happening here?

Let me share a few thoughts regarding this..

Did you know Deers and Mynas have a Mutually Beneficial Relationship?
As with most of the mammals, Ticks are a huge problem as they are a blood sucking parasite and will gradually weaken the mammal if not kept under control. The Myna, who eats the ticks of the Deer, benefits as it gets plenty of food and the Deer benefits from having the parasites removed!
This interaction between them is known as ‘ Mutualism ‘ (a type of symbiosis).
Both parties Benefit from the Interaction – One of the Best Mutual Relationships that is Witnessed in Nature.
And the Jungle is full of such Relationships.
