Marshal agrees to chop up the bird (5)

Ross

I believe the answer is:

galah

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

'bird' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?

'marshal agrees to chop up' is the wordplay.
'GALAH' is hidden backwards in amongst the letters.
But, I am not sure how this is indicated.

'the' acts as a link.

Can you help me to learn more?

(Other definitions for galah that I've seen before include "Fool" , "Simpleton" .)
