Yes they do have Ground Hornbills and they are a mated pair. You can find them in the Binowee (sp?) landing exhibit which used to house Lorikeets many years ago. Its across from the Great Hornbill.
Another zany incident is being reported by local TV stations: Someone broke into the back of one of the exhibits in the Primate Center and stole Banana Sam, a 17-year-old squirrel monkey! Reward is 5,000 bucks and he can be returned 'no questions asked'.
This isn't the first animal burglary for SFZ, in the 90's they had two koalas stolen from them around this time of year. The koalas were found about 2 days later and were returned to the zoo
