Archery. The griffon rider gains a +2 bonus to attack rolls it makes with ranged weapons.

Multiattack. The griffon rider makes two attacks with its melee or ranged weapons.

Battleaxe. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Eye of the Eagle. The griffon rider selects a target it can see. As long as the griffon rider maintains concentration, it can attack the selected target without disadvantage on attack rolls from its Poor Depth Perception. The griffon rider can end this effect as a free action, literally in an eye blink.
 Should the griffon rider already have an Eye of the Eagle target when it uses Eye of the Eagle, the griffon rider gains advantage on its next ranged attack roll against the selected target if it still has concentration.
