Gullgender

Gullgender is a form of xenogender where one feels like gulls are connected to their gender, either strongly identifying as them or simply just wanting to incorporate them into your gender better to understand their identity. Gullgender was made with neurodivergent and gull or gull-adjacent kintypes in mind, but anyone can identify as gullgender. This means it can be considered a neurogender, but is not exclusively one. It can also be considered faunagender, biogender, or birdgender, but does not have to be.
