Birds getting them all?

Put a paper or cloth bag over the head when the seeds start to form. Or when you see birds taking an interest in them.

I put paper bags over mine. I punch a few holes in it. Not sure if that's necessary. Keeps the birds off. I was able to harvest a couple large heads of black sunflower seed and it was just awesome. Have more that just bloomed.

OK THANKS. I'll give it a try.
