Cool little trick I found while running from a bird in Skettis. I happened to aggro one, and with the nerf to evading them by flying vertically, I decided the best way to get rid of it would just be to kill it.
The closest thing to me to land on was one of the tree trunks that have eggs in them (around 20 ft tall, basically half a tree with no branches). I landed in it, dismounted, and starting swinging at the bird, only to notice it was evading. After a few seconds of this, it flew off and resumed it's path. I searched skettis evade and skettis bird and I didn't see this method. Good luck and happy questing.
