I'm undecided. We've never had that many dead babies before, I've never fed through summer before and it's a long time since we had such a cool wet early summer here. Too many variables.
Most od the casualties were goldfinches and green finches but that might be because that's what we've got most of. I wondered if the fat balls and sunflower seeds weren't good food for the babies
