Hi Nick, I've been thinking about this too. Been thinking about animals in New York in particular. I've had plenty of animals eating my stuff. Almost all of them leave the plants looking chewed on except for birds. In my experience they are the only ones that leave the plants looking like the leaves or branches have been cut off with scissors. Nice, clean, straight cuts. Here's the interesting part. I have lots of small gray birds, think canary size, that will clip huge leaves of my broccoli and cabbages. But the leaves are far too big and heavy for them to carry them more then a few feet. I often see lots of leaves a few feet away right next to the fence. They can't fly that high with such big leaves. Makes me wonder wonder what large birds are building nests right now. Gotta say, I would really love to know what is causing the damage.
