Experiment - switching to Safflower seed to deter sparrows

14 years ago

Recently, giant flocks of sparrows have been hitting my feeder and emptying it in a day. I like to reduce their numbers by switching from black oil sunflower seed to safflower seed. I like to see if this will deter them.

I want to know how to switch over? I am currently being visited by mostly chickadees, cardinals, house finch, and some red wing black birds. I am sure switching over will probably lose the red wing black bird, but would a sudden switch cause the other birds to come to the feeder. Should start with a 50/50 mix and then switching over to safflower?
