Hi there! I live in Orange County, CA and I'm hoping someone can help me. I feed mainly sparrows and finches and they typically only eat black oil sunflower seeds. I have specific food for the finches but the sparrows don't touch it. Anyways, in about the past 3 weeks I've found about 7 dead sparrows. I feed the birds in my front yard and side yard and that is where I'm finding them. I am very lucky to have a bluebird nest and there was a dead sparrow right underneath the nesting box and I kind of shrugged it off but now I'm wondering if the bluebird could be killing them? I've read about disease and I've already taken down my feeders but I wasn't sure how long I should wait before filling them back up again. I've also had trouble with birds flying into our sliding glass window and I've since put up a screen so that they won't fly into it. The front yard doesn't have a screen though and that is where I'm finding the majority of these little guys dead.
Just wanted to see if anyone else has dealt with this sort of thing. I've been lucky enough to have bluebirds nesting for the past 3 years and this is the first year that one of the birds is a little feisty. The bluebird will swoop down if he sees anyone walk underneath the nesting box. It's up really high and no one could look inside it even if they wanted to but the bluebird isn't taking any chances.
Any information you can provide is appreciated. Maybe I shouldn't be feeding them black oil sunflower seeds?
