For our guests at the San Diego Zoo Safari Park, as well as our Tiger Cam viewers, it’s not uncommon to see the tigers roaming the perimeter of their yards, or even strolling back and forth across a smaller area. This activity can be attributed to a number of factors, many of which are a clear reflection of life for their wild cousins. In the wild, tigers patrol the perimeter of their territory on a regular basis and can sometimes walk more than 10 miles in one night while hunting. Consequently, we consider it a natural, species-appropriate exercise when they cruise their territorial boundaries, whether it’s to check out the smells left behind by another cat the day before, to remark the borders with their own signature scent, or to just make sure that everything is well within their domain!
The perimeter fencing around Tiger Trail keeps the local mule deer from ever getting into close proximity with the tiger yards. At the former tiger habitat, we’d frequently have deer around the perimeter of the exhibit and on the trail by the catch pen, and all the cats would do was sit and stare…for hours! Our tigers have it pretty good within their yards; they have all their needs met and basically get everything served to them on a platter, so they have no real motivation to “expand their territory.” And while tigers are capable of climbing, they’re pretty inefficient at it, especially once they’re full grown.
Typically, when we see the cats walking back and forth across a smaller area, it’s because something has them particularly inspired. Often, this can be the anticipation of an upcoming training session, especially if one of their keepers is in close proximity. Sometimes, however, their excitement has more to do with the other tigers. For example, when one of our females is in estrus, we’ll often see an increase in activity from them, as well as our adult male, Teddy. Also, as the cats are still acclimating to all of their new human guests, we’ll sometimes see them become a bit more enthusiastic when they catch sight of a particular passer-by (usually one of the smaller ones!). Our guests often, albeit unknowingly, provide a great source of environmental enrichment for the tigers.
If helping to enrich the tigers sounds like fun, be sure to visit us on Tuesday, July 29, when we’ll be celebrating Global Tiger Day! We’ll have keeper talks, training demonstrations, and enrichment-building workshops, where you can create real tiger toys and then see them put to use! It will be a day not to be missed for all of our tiger fans. Be sure to come out and show your stripes!
