Field Frame Friday: Happy Valentine’s Day!

Titi monkeys are pair-bonding monkeys. They engage in affiliative behaviors like the one depicted here: tail twining! Titi monkeys tail twine during the day in order to maintain contact with their partner, similar to hand-holding in humans. At night, titi monkeys tail twine to maintain proximity and help each other balance while sleeping! Happy Valentine’s Day!…

Field Notes: Singing Titi Monkeys

A typical morning of titi monkey vocalization recording starts off with a 4:30 AM alarm. I roll out of bed, start coffee, and am out in the door in under ten minutes. The 20-minute drive goes by quickly as I mechanically drink my coffee. As I gather my recorder, microphone, and camera, interns begin to show…

Newsroom: Monkey Eye Tracking

Photographs of CNPRC titi monkeys (Plecturocebus cupreus) and rhesus monkeys (Macaca mulatta) [Source] In a collaboration between the Bales and Bauman Labs, researchers at the California National Primate Research Center (CNPRC) at UC Davis have validated a new method for eye tracking in non-human primates.

Field Frame Friday: Early mornings

Jungle breakfasts are usually creative: most gibbon groups begin singing as the sun rise, so breakfast is always eaten in the dark and often accompanied with a beautiful chorus. Each morning, we did fixed acoustic surveys based off two observers in order to triangulate group locations and estimate gibbons densities within our field site.  Pictured next…

Creature Feature: Wild turkey

In Northern California, turkeys are a common roadblock, daily hazard, and yearly Thanksgiving staple. However, people rarely take a second to stop and appreciate these animals’ interesting behavior. There are actually two species of turkey, Meleagris gallopavo that ranges from Mexico to Canada and Meleagris ocellata that lives exclusively in the Yucatan Peninsula1. This creature…

Field Fiasco: Gibbon Tease

When working in Sabah, Malaysia, I encountered some of the most frustrating primates I’ve ever worked with. That’s really saying something, considering that I now work with the very mischievous Rhesus macaques. To this day I still remember this frustrating group of gibbons, which I called the “office group.” During my 2015 field season, I…

Ecotourism: National Parks

This week, we conclude our series on ecotourism. This time, we are featuring opportunities that are a little closer to home. Whether they know it or not, many people in the United States engage in ecotourism in their own backyards. The National Park Service, founded in 1916 by President Woodrow Wilson, oversees 417 areas in…

Ecotourism: Reading Monkey Faces

When traveling, it’s common to run across non-human primates—such as spider monkeys, squirrel monkeys, capuchins, and rhesus macaques— either in a wild or captive setting. In some tropical tourist destinations, locals will carry these animals, eager to hand them over for a quick picture and a few dollars. In other places, tourists have the opportunity…
