Peacocks are larger than other Groundfowl.
Limited flight: Groundfowl have a flying speed of 20 feet, and they cannot hover. They can only fly if they are not wearing medium or heavy armor.
Keen sight: Avians have advantage on Perception skill checks that rely on sight.
Talons: Avians deal unarmed strikes with 1d4 slashing damage.
Flare display: Once per long rest, Groundfowl can cause all creatures within 10 feet who can see them to make a Wisdom saving throw (DC 8 + Charisma modifier + proficiency bonus) or be distracted (disadvantage on the creature's next attack roll).
Radiant display: Peacocks may cast Color Spray once per long rest without components. When they use their Flare Display, creatures also have disadvantage on their next attack roll if the creature fails the save. Peacocks have advantage on Charisma checks against creatures attracted to beauty or flamboyance.
