Translation:Which animals have green feathers?
Oh, so that's why there were translations to fit in this course? Smart. Green owl as a symbol of language skills you shall master here. Did not see that coming. Not bad, Duolingo.
'What' animal is the same as 'which' animal, and 什么 usually is used as 'what'
