There's 7 with the baby. Mom Clare, dad Dolce, big sister Hadley who are all on exhibit with baby. Then off exhibit are grandma Rosalie, and uncles Hayden and Jack... unless Rosalie has passed away due to age.
Thanks TZFan! On my past few visits to the zoo, I've had to rush through the Americas pavilion, so I never really had time to watch the tamarins and other monkeys.
Never a problem Arcticwolf. That info came from the SSP and I think it was pretty recent. Hayden and Jack were being kept as companion animals for Rosalie because they didn't want her in with Clare and Dolce and any babies. As a mother of 8 Rosalie is well enough represented and Jack and Hayden I believe have been neutered. Clare and Dolce have just Hadley and the new baby so there could be more babies to come in the future.
