Aarakocra, Labored Flight (5e Race Variant)
From D&D Wiki
A simple rebalancing of the aarakocra. A flight speed is very powerful, especially in the early game, as it allows characters to fight at a range out of the reach of most other creatures and effects. The Labored Flight trait, initially detailed in the Stylvix race, alleviates this, allowing for more traits to be added. Allowing flight with heavy armor makes heavily armored aaracokra viable without them losing their "only" trait.
Size: Your size is Medium.
Speed: Your base walking speed is 25 feet.
Sharp Vision: Whenever you make a Wisdom (Perception) check related to perceiving far away creatures or objects, you are considered proficient in the Perception skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.
Talons. Your talons are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
