Munching hay, animal in high-up region (9)
I believe the answer is:
himalayan
'munching hay animal in high-up region' is the definition.
I can't tell whether this definition defines the answer.
'munching hay animal' is the wordplay.
'munching' indicates an anagram (letters crushed or munched into a new form).
'hay'+'animal'='hayanimal'
'hayanimal' is an anagram of 'HIMALAYAN'.
Can you help me to learn more?
(Other definitions for himalayan that I've seen before include "Of a South Asian mountain range" , "from area of highest population" , "in highest position in Asia" , "Of the mountains between India and Tibet" , "Like some mountains" .)
