Okay, it appears that reptiles do NOT have pheomelanin:
"Birds, like mammals, produce both pigment types (for a review, see Mundy, 2005), but reptiles lack pheomelanin (Ito and Wakamatsu, 2003), suggesting that either reptiles have the lost the ability to produce pheomelanin or that mammals and birds independently have evolved the ability to produce pheomelanin."
