I thought Geladas were moved into Papio?

One of my favorite exhibits at the Bronx Zoo, particularly for the ibex in the same enclosure. I could have sat there all day and watched.

Please educate a west-coaster about conditions in The Bronx. Are Geladas and Ibex allocated more green grass per individual than people are?
Posted by: Gaythia | November 18, 2009 12:16 PM
Gunnar; I have heard that suggestion, but it is not definitive. As far as I know it is still being hashed out and for the moment I prefer to keep them in a distinct genus.
Andry; And the rock hyraxes, too! This is actually the first time I have ever seen any kind of antagonistic encounter between the geladas. It was quite spectacular.
Gaythia; In the Bronx, definitely.

Great picture, looks like one has a momentary bipedal stance, perhaps in between leaps. I think geladas are clearly distinct (more upright posture) morphologically and behaviorally from Papio, but nowadays I don't know if that matters as much. BTW anyone interested in baboon hybrids might google 'kipunji baboon' for a recent article on it.
