As I was watching visitors feed the giraffes (see yesterday's photos), I noticed that some of the giraffes paid no attention to the carrot treats and so I asked the zoo staffer about this. She explained that one of the females, Denver, was very aggressive with the other giraffes at snack time and nudges them to stay away. If there are a lot of people gathered to distribute carrots, the other giraffes will venture over to the platform to get a treat. Otherwise, they browse from their tree top baskets (photo 3).
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
