Considering you'll encounter these birds in the first area you'll be sent to after leaving Uhra, they're not huge threats. It will take a couple of hits to take them out if you haven't leveled up yet, though if you've equipped Kaim with a bruiser ring, he should be able to take them out with one hit, if you score a perfect. Once you level a few times they'll be cake. You have to watch out for their Rapid Descent attack early on though; it can do around 80 damage the first time you encounter them, and that early on this is a fair amount of your health.
