New baby animal alert!
The gray titis are part of a mixed-species habitat that recreates their native South American rainforest in the zoo's World of Birds.
Luckily for zoo visitors, these primates are active during the day and hang out in trees. They're also monogamous, with males helping to raise babies, so watch for some family "aaaw" moments. (Yes, this is one of the species that wind their tails together, in case you didn't think they could get any cuter.)
Check the family out in action in this video, and if you'd like to see them in person the Bronx Zoo is just expanded its hours to 5 p.m. on weekdays and 5:30 p.m. on weekends through October.
