12:24 There's a tree full of vultures at the corner of my territory. Twelve. Twelve vultures. Hope they're not feasting on the tiny carcasses of my monkey family...
1:02 Still can't find my monkeys. I NEED SOME DATA. Titis - where you at??
1:58 Why does it smell like bacon?
2:53 No monkeys yet. Screw this, I'm eating lunch.

I finally had a breakthrough around 4:30. A neighboring titi family began to vocalize, and although my group was unresponsive at first, they eventually chimed in with a reply to the initiators of the bout. I spotted two individuals (the same two individuals from last Wednesday) in a tree at the northwestern corner of the territory (near the same tree I found those two in last Wednesday). I saw my male - carrying the infant, as always - but I was still unsure of his companion. Female? Subadult? At this point, there was no way to tell. As a small, grey juvenile approached the duo, I heard nearby vocalizations from two additional monkeys. I was really starting to think that these were the two older offspring of my family...staying far away enough to kind of do their own thing, but still close enough to check in with their folks to let them know everything's okay. These suspicions were confirmed when I noticed my male pass the little baby titi over to the other individual, where I watched the baby nurse. That's a pretty clear indicator that the duet consisted of my male and my female, with the juvenile sticking close to mommy and daddy. It was at this point, while my female nursed her youngling, that I witnessed my first case of 'scent marking' behavior. There are two kinds of scent marking: anogenital rubbing and chest rubbing. I was witnessing the latter, as my male moved his chest with pressure and friction against a tree branch by sliding his body forward. Only a few minutes after this behavior, I was able to watch my male and female actively groom one another. It may have taken me a while to find them, but it was fantastic seeing all these different behaviors.

FUN SCIENCE FACT #8: To avoid predators, a mother Slow Loris (genus Nycticebus) licks the offspring with her toxin-laced saliva before sending them off to search for food. What a good mom.
