As long as we're talking about corvid capture methods,
Maser (1974) described ravens team hunting feral Rock Doves
at Succor Creek Canyon, Malheur Co. OR, driving them into
the water as a method of capture.

If one can get past the Bambi syndrome, the methods by
which predators do their work can be quite fascinating.
