Bird that could be a parrot mother keeps at home (4)

'bird that could be a parrot' is the definition.
'mina' can be an answer for 'bird' (alternative spelling of myna). I'm not certain of the remainder of the definition.

'mother keeps at home' is the wordplay.
'mother' becomes 'ma' (Ma is another word for mother or mum).
'keeps' indicates putting letters inside (inserted letters are kept inside).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'ma' going around 'in' is 'MINA'.

Can you help me to learn more?
