I wish SE wouldve told people how to get the buffs and gifts before they ended. I mustve passed these birds like 100 times and asked people who told me they're just decoration attractions. Couldve helped me fishing in Windy >.<
It also appears in South and North Gustaberg, probably other areas too. Also, in exchange for a random item, it gave me an item, called something like "New Year's Gift." It was a consumable, and when used, it gave me a buff that increased fishing skill.
i got the same thing too. I had traded a 'Quadav Fetich Head' to it in Pashow Marshlands and got the 'New Years Gift'. I was hoping it was exp, kinda like eco-warrior, but it was fishing imagery :\ some gift lol.
