We had a small patch turned over last year at Treasure Island Park here in
Twin Lakes. At first I thought that the crows were following up on what the
raccoons started at night. The chunks of grass seemed to be too large for
crows, however I have observed them since and they are indeed the culprits.
This year the damage is more extensive and has spread to neighborhood
lawns. I have never before observed this behavior from crows. Makes me
wonder if these grub infestation come in cycles?
