Name briefly associated with animal sanctuary's birds (8)

'birds' is the definition.
(titlark is a kind of bird)

'name briefly associated with animal sanctuary's' is the wordplay.
'name briefly' becomes 'titl' (I can't justify this - if you can you should give a lot more credence to this answer).
'associated with' says to put letters next to each other.
'animal sanctuary's' becomes 'ark's' (as in Noah's Ark).
'titl'+'arks'='TITLARKS'
