I mostly view it from the psychological perspective, tying my 'types into neurodivergent traits (ex. animatronic due to muted emotions from autism, corvids/other birds due to imprinting, dragons related to being strong after trauma, etc.)
However, there are certain 'types that have a bit more behind them.
My Resplendent Quetzal and Golden Eagle 'types feel deeply ingrained within my being, which I relate to my heritage (Mexican)
The Resplendent Quetzal is a shy bird that lives in southern Mexico (not exactly where my family is from, but close enough) and the Golden Eagle is the literal symbol/national bird of Mexico. It's even on the flag:
Hopefully that image loaded. If it didn't, literally just google "mexican flag".
Anyway, even the Golden Eagle's name in Spanish (Águila Real) feels central to my connection with it. It's a symbol, both for myself and the country of my heritage.
