I've had this one in the queue for years but kept putting off placing it online because it's just a "zoo" photo. Well, I've got so many projects going right now that I'm finding it hard to process new photographs and this one was available, so, here you go!
I captured these two playful nyala's butting heads in their large enclosure. It was more of an affectionate activity than a dominate one, and there was much licking and rubbing involved -- very cute! I was trying hard to get rid of the tree on the right, but they pretty much stayed where they were and my vantage point was the only good spot from which to shoot, so this is the best composition I could come up with at the time.
