I found a feather up by falls creek, how do I know what type of bird it belongs to because it is a big Feather ?

If you send me a photograph of the feather I can help with identification and advise you on wheter it is legal to possess. You may also call me at our Regional Office in Idaho Falls.   Regards, Rob Cavallaro, Regional Wildlife Biologist rob.cavallaro@idfg.idaho.gov (208) 525-7290
