Local woman building an aviary (9)

I believe the answer is:

birdhouse

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

'aviary' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'local woman building' is the wordplay.
'local woman' becomes 'bird' (bird is a kind of woman. I am not sure about the 'local' bit.).
'building' becomes 'house' (I've seen this before).
'bird'+'house'='BIRDHOUSE'

'an' is the link.

Can you help me to learn more?

(Another definition for birdhouse that I've seen is " American nest-box".)

I've seen this clue in The Irish Times.
