Indian bird, mostly gets garlic, perhaps (4)
I believe the answer is:
bulb
'garlic perhaps' is the definition.
(garlic is a type of bulb)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bulb that I've seen before include "Reproductive organ in some plants" , "swelling" , "Tulip, for example" , "A tulip grows from one" , "Light fitting" .)
