Crysa’s Flyers is a new pet daily from the 7.1 patch. She can be found north-west of Far Watch Post in Northern Barrens (63.6, 35.8). You will need to complete Battle Pet Tamers: Kalimdor, Battle Pet Tamers: Eastern Kingdoms (and possibly Taming Kalimdor) to unlock this daily.
Her team consists of 3 max-level epic carrion birds:
Cherry: Wild Winds, Glowing Toxin, Predatory Strike
Swoop: Thrash, Hawk Eye, Cyclone
Buzz: Reckless Strike, Preen, Lift-Off
Team: Enchanted Torch, Ethereal Soul-Trader, Levelling pet
Alternate team: Chrominius, Enchanted Broom, Levelling pet
(similar to my Vesharr team from Draenor)
This is not a difficult fight so feel free to have some fun with her flying trio.
