The olfactory system of Turkey vultures is unique even amongvultures.  The olfactory bulb of theirbrain is absolutely the largest of N American vultures and significantly relativelylarger compared to brain size of any of the world’s vulturine species.

Perhaps more important is the enormous number of mitralcells packed into the Turkey Vulture’s olfactory bulb.  Mitral cells are specialized neurons thattransmit olfactory inputs to other neurons, like a chorus repeating andamplifying the protagonist’s message.  Hence,Turkey Vultures are able to detect even the slightest quantity of protein degradationgases in the air column.  <>


I couldn’t find anything on Bald Eagles’ olfactory systemsbut Golden Eagles apparently have a significant amount of their genome potentially devotedto olfaction. <>
