>Really, what's the source of protein in the nectar? Does the plant secrete nectar with high protein, is the protein from contamination with pollen? I wouldn't expect to see any significant amount of protein in nectar. Does heather produce both nectar and pollen that would be collected by bees, or is it mainly a nectar source?
Pollen - heather honey is rich in pollen. Bees collect both nectar and pollen.
