My Dad and I hunted crows for sport in the 40's by hiding in the rip-rap along the Missouri river. We were on their return flight path as they came in to their bottomland roost. We got lots of passing shots that way. I was told that one could unload a pile of gravel amidst the roost area, load the base with dynamite and then set it off at night to take out much of the colony. But that's not on topic here. Now, in my immediate area, the crows seem to nest in the hedgerow some years and other years they nest elsewhere But I never see thousands in a roost like I did as a kid. All of nature is seen in farming/gardening......The Coons, opossums, squirrels, the drought, the hail, the rain the weeds and bugs etc. Crows are just another one that come and go. And "Yes", it is hard to believe that they are a protected species....maybe Crabgrass will be the next such species.
