The most remarkable difference is in the neck. The Grey-necked Wood-Rail's neck is completely grey as if a hood. The Giant Wood-Rial is two-coloured and the grey of the front part also covers the breast. The rear part of the neck is chestnut. Its abdomen is rosy.
The Grey-necked Wood-Rail's breast and abdomen are rufous.
There is a difference in size. The Grey-necked Wood-Rail (36 cm) is smaller than the Giant Wood-Rail (42 cm). They frequent the same habitat and behave in a similar way.
