Hola,
Looking at his page....the Buzzard is red to a much lesser extent.
Good observation, though -- it makes sense that H's would still show
at least some hematite presence, if that is was causes the red
coloration.

The first link in my last email goes against what you say above. Note
that the pictured stone has a black, frothy rear and a reddish
shield-shaped front.

Regards,
Jason
