Perhaps people should learn from the old adage:
stop feeding the animals... (with tainted bulk food you bought at lowes/homedepot mass produced in China)?
The other night we had a bunch of seagulls hunting butterflies and moths above us. At first we thought they were attacking us, but after a few times we noticed they were simply hunting. Their prey, in their turn, are mostly busy devouring a patch of nettles on a slope at the end of our property, and so they're keeping the nettles in check AND the birds fed.
As a bonus, I don't have to mow the lawn either.
But, mostly, they're concerned that whatever's going on is contagious and could potentially spread when birds congregate at feeders. It's hard to convince birds to social distance.
As a side effect, I get nicely social distanced animals. During the most crowded times there are still ~3x as many piles as there are simultaneous diners.
