Every Sunday morning, the Crows that visit our street, make it their mission to pick at and remove the plastic wrapper that our Neighbor's Sunday newspaper is delivered in.
The other Crows, sometimes, as many as 6 or 7, serve as "lookouts", just in case somebody might catch them in the act.
I think, the Crows are trying to clip out (peck out), coupons, before they do their weekly shopping.
