Male hawks’ cries let out (8)

I believe the answer is:

tiercels

I'm a little stuck... Click here to teach me more about this clue!

'male hawks'' is the definition.
'tiercels' can be an answer for 'hawks'' (tiercel is a kind of hawk). I am not certain of the 'male' bit.

'cries let out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'cries'+'let'='crieslet'
'crieslet' anagrammed gives 'TIERCELS'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
