'light' is the definition.
(lantern is a type of light)

'article probing origin of little-known seabird' is the wordplay.
'article' becomes 'an' (indefinite article).
'probing' is an insertion indicator (probe can mean to make a hole in).
'origin of' suggests taking the first letters.
'known seabird' becomes 'tern' (tern is a kind of seabird. I am not sure about the 'known' bit.).
The first letter of 'little' is 'l'.
'l'+'tern'='ltern'
'an' put within 'ltern' is 'LANTERN'.
