you cant just out sunflowers seeds on a grill. You can get a pan put them on then set it on the grill only if they came off you sunflower plant thought
Yes, most of them do, in fact the seeds are very good for birds. If you just leave the flower head to seed on the plant the birds can come and get them, or you could harvest them yourself and place them where birds can find them.

They survive by reproducing. Sunflower seeds are protected by a hard woody shell that allows them to withstand weathering until it is time to germinate.
