"The male and female (of the pheasant) appear very different. The male has a red face, a longer tail, and dark-green neck, breast and stomach, while the female is a light-brown color with black spots and a shorter tail." I found this sentence in an English textbook published in Japan. “Neck, breast and stomach” are all countable nouns. Why don’t you say “a dark-green neck, breast and stomach” in line with "a red face, a longer tail"? Thank you in advance.
