Adú Kaqué and Ogundá-Obara
(It's not a great picture, but you can see the osun in the center rear.)
Similarly, the Arará-Sabalú give an osun called Sain when they give a new initiate Asojano, and this osun also has the much more common rooster. Still, many lineages give this rooster-topped staff, and I would love to know about its origin in the different lineages.
