I've noticed it too here in southwest MN. I work in Canby, and in early August people began mentioning to me that their feeders were deserted. The most conspicuous absence was Robins. Other "town birds" like Chickadees, Grackles, Catbirds, Hairy and Downy Woodpeckers, Mourning Doves, Nuthatches were scarce as well.
Most of the towns in Lac qui Parle and Yellow Medicine Counties are full of Eurasian Collared Doves, but they prefer to feed on spilled grains at the elevators, so I don't think they're out-competing the others. Back in May, I located a few pairs of nesting Bluebirds, but after the heavy rain and cool weather mid-month, they either starved or abandoned their sites. Very few pheasant and turkey nestlings survived that period. There weren't as many Chimney Swifts this year. Nighthawks were fine, but all summer long, I hardly saw any bats, and a lot of other people have mentioned this to me. Wild grapes, berries, and nuts did very well this year. One pattern that's apparent is that the birds we're missing are all likely to live close to human activity. Beginning in August, Canby began spraying twice a week for a strange late-season mosquito infestation (there were virtually no biting bugs in May, June, or July). The spray had no effect on the mosquitoes, but coincided with the emptying of the feeders. Area farmers sprayed more this year than any year I can remember (the amaranth out here is now resistant to Roundup, so they're spraying Dicamba, which is more prone to drift and even the fumes will poison nearby plants during evaporation); in the last 2 weeks of July and first 2 weeks of August, we had crop dusters in the sky EVERY day, even during extremely windy conditions. I noticed some elderberry shrubs along field edges whose leaves showed the telltale cup-shaped shriveling associated with Dicamba, and the berries (which were intact) were stripped as soon as they ripened. Considering how much wild fruit grows along fencelines and field edges, and also knowing that it's decimated beehives around the country, I'm wondering if this summer's slash-and-burn pesticide offensive may have something to do with it. Circumstantially, the timing works out: peak wild fruit time, and also about the time when Goldfinches are nesting and eating wild thistle seeds.
