They can be a pain, like any small animal, as the population can get out of control. The neighbors outdoor cat gets it's share. I watched a Blue Heron Crane, who frequents our nearby creek, fly by my window the other day, and stand in one position, outside on the grass, and after 20 minutes, grabbed a chipmunk by the neck, and suffocated it, and after three drops and re grabbing it, and making sure it was strangled, finally, my wife and I witnessed it eating and swallowing it whole! We've never seen that before, living here almost 50 years back into the wooded few acres, and semi rural area.
