Why do mynas act aggressively when interacting with other bird species?
Some species of mynas (such as the Common Myna) have been known to act aggressively towards other bird species. This behavior is often related to territorial defense or competition for food resources. Mynas can be very territorial and will chase other birds away from their territory or food sources. The aggression can also be seen during breeding season when the birds are trying to protect their nests. However, it is important to note that not all mynas display aggressive behavior and that individual behavior can vary greatly.
There is similar kind of behaviour in other species aswell?
