Rooks

Whilst at Venus Pool NR Friday eve after work, I noticed 2 rooks were staying fairly close to one another, and every so often, they would hold beaks.... remain like this for a few seconds, then continue scavenging.

I took a couple of pics to show this (it was a bit dark!)

and again

Neither bird looks like a juvenile, so I don't think this is feeding. It looks as though one closes their beak over the other's.

Are rooks monogamous? Could this be a 'bond strengthening' thing? Or is is down to hierarchy? One being submissive to the other by allowing his beak to be clasped shut? There were no other signs of agression which makes me lean more towards the 'bonding' theory!

Would love to hear your thoughts!
