Swallow nesting, establishing shelters (6)

I believe the answer is:

ingest

'swallow' is the definition.
(I've seen this in another clue)

'nesting establishing shelters' is the wordplay.
'shelters' indicates the answer is hidden within the clue.
'INGEST' is hidden within 'nesting establishing'.

(Other definitions for ingest that I've seen before include "Consume food" , "Eat - gin set (anag)" , "Scoff" , "Take (food) into the body" , "take in, eat" .)

I've seen this clue in The Telegraph.
