That reminded me of a story. I was over a friends house, standing in the back yard, and 3 bluejays were dive bombing/chasing a cat across the yard, the cat was trying to run away but the blujays were relentless, they wanted the cat OUT of their territory, there was no letting up until the cat was out of the back yard.
Perhaps the bluejays were protecting a nest? They were vicious!
That was the first, and only time, I have ever seen birds chase a cat, different.
