Fancy benign, sweet conclusions by bird (6)

I believe the answer is:

cygnet

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

'bird' is the definition.
(cygnet is a kind of bird)

I cannot understand how the remainder of the clue works.

(Other definitions for cygnet that I've seen before include "Little swan" , "Baby swan (ugly duckling?)" , "Young aquatic bird" , "small pen? Possibly" , "Immature swan" .)

I've seen this clue in The Hindu.
