Does not need to be included as a trait on the masterlist.
Browbirds can have many kinds of ears! You are not limited to the examples shown.
All browbird ears should be pointed or come to a rounded point. They can have short or long fur. They can be asymmetrical in style and fur placement, have piercings, and have holes/light tattering.
Ears should not be much larger/longer than the largest examples shown below with some wiggle room for fluff. Ears larger than about x1 head size would need the super long ears rare trait. Feathered or wing ears are a hiros exclusive trait.
