These birds are found outside the map so it may be hard to find bc i have no screenshots but here are the locations..

Outside near soe portal in spawn
Near teddy bear part for pap..on the beams of the ceiling
Outside on a fallen tree branch near cabins
Face banana Colada and look out on the roof to the right..on ledge...
Go to spawn and pick up golden bird out of cage
Go to the weird blue room all the way under map and place on pedestal
