More than one mountain creature in the same place gets very cold (6)

I believe the answer is:

ibices

'more than one mountain creature' is the definition.
(plural of ibex, a mountain goat)

'in the same place gets very cold' is the wordplay.
'in the same place' becomes 'ib' (short for ibid, in the previously cited source).
'gets very cold' becomes 'ices' (as in water icing over).
'ib'+'ices'='IBICES'

I've seen this clue in The Guardian.
