Lovely animal! I guess this is the only olinguito in captivity in the world. I had a short stop in Guayllabamba at a small store when I was in Ecuador and saw the entrance of Quito Zoo, but unfortunately time was lacking for a visit.
Yes, certainly the only zoo I'm aware of with the species and a total surprise when I arrived! They had at least 2 on exhibit, possibly one more behind the scenes.
Main reason I visited was for the Little Red Brocket. I was set to travel to Eco Zoo San Martin based on your photos of that species, until I got word that Quito's zoo had one!
