Birds where I hunt are lower in numbers, but I am also seeing more eagles. I believe a turkey in the open fields is an easy target for an eagle. The few turkey that are around my area seem to be avoiding the open fields. At one time a turkey that was out in the middle of an open field was safe from most ground predators, because the turkey could see a predator coming, now with eagles this will not be a safe place. Another thing I noticed is more killed by owls, while the turkeys are roosting. Two years ago we found 5 birds in two different roosting areas, that owls killed, these were adult birds in the winter. Then you have the increase in coyotes, they come running to a turkey call for a reason. And then there are now fishers. When you increase predator numbers, they increase their impact on prey. As for west nile, it also kills hawks, owls, crows , bluejays, and eagles, and all these predators seem do be holding steady or increasing in numbers. It seems odd that if west nile kills so many different species, why is it that the prey birds, like grouse, quail, pheasant, woodcock and turkey are dropping in numbers, and predator birds seem unimpacted. Could be all the predators are having an impact, they have to be eating something.
