honeyeater

'bird' is the definition.
(I've seen this before)

'extremely tame adopted by hotel four seasons?' is the wordplay.
'extremely' says to hollow out the word (remove centre letters).
'adopted by' means one lot of letters goes inside another (I've seen this in other clues).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'four seasons?' becomes 'oneyear' (I am not sure about this - if you are sure you should believe this answer much more).
'tame' with its middle removed is 'te'.
'h'+'oneyear'='honeyear'
'te' going into 'honeyear' is 'HONEYEATER'.

Can you help me to learn more?
