Do not use short-ranged tankers against these feathered fiends, as the Toxic attacks will cripple them in almost no time; instead, rush them down with units such as Awakened Bahamut Cat and Bullet Train Cat. Fishman Cat is massively useful against him, as he moves fast and takes down a good portion of his health per hit (a level 50 Fishman can turn it into a good Thanksgiving meal in just 4 hits, 3 with a level 8+ Attack Buff Talent). However, be wary of not timing your rushers wrong and that there aren't bulky enemies in front of them, as these could shield this Toxic avian from your rushers' attacks.
