They don't seem to be afraid of climbing into the trees, and their keeper mentioned today that they are even going in the pool occasionally.
The brother and sister cubs Tikal and Maderas chased each other around quite a bit. If I've got it right it was Maderas, the female, doing most of the chasing. By the way, many of these shots have been cropped quite a bit to make them bigger and get rid of distracting parts, but sometimes I just couldn't completely get rid of the out of focus tree branches that were between me and the cubs.
This looks like a little baby jaguar face-off.
The cubs' mother Nindiri was right there the whole time - occasionally they would all 3 get together.
It looks like she's got little Maderas in a headlock here.
Here are a couple shots of Nindiri as she was wandering around the enclosure.
