Bird with head stuck in bird feeder?

Try helping your bird my wiggling it out! If that still doesn't work get some baby oil and put it on the birds neck and then try again. If that still doesn't work try melting all of the plastic. You could even cut the plastic with a pair of scissors or a knife and make a very small "necklace" around the bird and then cut that piece off. Make sodering your last resort because of the heat it could lead the bird to possibe injuries! Good luck!
