Canadian Goose

Collaboration. With each additional goose within a 100ft radius save DC for frightened increases for each goose in the area. 

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft, 1 target. Hit: 14 (2d8 + 5) [piercing] damage. 

Charge. If the goose runs 15ft towards a target with intention to attack or towards a foe the target just make a DC 14 Dex save or trip in fear. If already on the ground then DC 14 Wis save or become frightened. 

Honk. The goose lets out a roaring honk in a 15ft cone. Any non goose creature must make a DC 14 Wis save or become frightened of all geese in a 10ft radius. This does not effect constructs.

Honk. If another goose is hit within a 10ft range a goose may use its reaction to honk to attempt to scare off the predator. (Refer to Honk attack but only targets one)
