I live in Jefferson County, NY, 10 miles from Canada. For the past 20 years each spring has found Grackles nesting in the vines on the cow barn, Barn swallows in the manger and starlings in very cavity in every building.
This year the grackles and starling were t the feeder but have moved on and the barn swallows never showed up.
Lack of food or global warming?
