These are the most gutsy mynas I've ever observed.
There's a common myna bird couple in my neighborhood that's vicious and annoying. They claw other myna couples, and peck on my ventilation holes during the spring and summer.
Last month, they penetrated one of my ventilation holes and made a nest in my ceiling. After I removed their nest and blocked that hole, they got even by pooping all over my deck.
Now today, that couple harassed and clawed a cat! That couple stalked a cat down the road while squawking, and swooped in to claw it!
Those birds must have been a crow in its past life, because mynas aren't known to attack larger specious...
