Another thing I saw at a park: The crows surrounded a swan. One would pick at the swan's butt. When the swan turned around, another would do it. It looked like they bullied the swan for entertainment.
And, from my experience, don't atteack random people but those that got to close to their nest. Whatever their definition of close is.
We only have a couple of species of crow and if you're on the east coast then you're pretty much guaranteed to be seeing ravens. The crows are in the centre and the west coast, in the dry parts.
We exposed wild crows to a novel ‘dangerous face’ by wearing a unique mask as we trapped, banded and released 7 –15 birds at five study sites near Seattle, WA, USA. An immediate scolding response to the dangerous mask after trapping by previously captured crows demonstrates individual learning, while an immediate response by crows that were not captured probably represents conditioning to the trapping scene by the mob of birds that assembled during the capture. Later recognition of dangerous masks by lone crows that were never captured is consistent with horizontal social learning. Independent scolding by young crows, whose parents had conditioned them to scold the dangerous mask, demonstrates vertical social learning.
A local sod farmer told me they shoot one and leave it dead in the field. All the other crows show up for a crow funeral and when they leave they dont come back. They remember the crow that died there and treat the area as dangerous.
So you can let the crows have your grubs, or the grubs your grass.
