Hello and Welcome Back!

Super Rare....Super Important---The Rufous Tree RatI had this blog written and ready to publish last week, then we got some really exciting news. We identified one of the rarest mammals in Costa Rica on one of our cameras! How rare? We are likely one of about five sightings.
|This may be the lowest recorded sighting of the arboreal Rufous Tree Rat at less than 2 meters above ground.|
|Short ears and black tail are just a few of the distinguishing characteristics of Diplomys labilis.|
When I could not find the above rat in my field guide, I recalled that an arboreal rat had recently been discovered living in Costa Rica…I looked into a Tico Times story about Costa Rica's 250 mammal species . The Rufous Tree Rat was only discovered to be in Costa Rica in June of 2015. I sent images via email to the researcher mentioned, José Ramírez, with images of our buddy. Late Friday afternoon he confirmed, with 90% certainty and 100% enthusiasm, that it is indeed the Rufous Tree Rat. Here is his description of the finding Here is his description of the finding.
I was later contacted by Naturalist Jim Córdoba_Alfara, who actually photographed the Rufous Tree rat for the first time in Costa Rica at La Tarde Lodge on the Osa Peninsula. He confirmed our sighting and is including our project’s images in an upcoming paper about this understudied and poorly known rodent’s natural history. While called an arboreal or Tree Rat, the the Rufous Tree Rat and its close cousins are more closely related to guinea pigs and chinchillas of South America.(via Canopy Family Website)
Other New Visitors

|My what a big tail you have!|

We were also visited by the Neotropical River Otter again. This time it was actually in the water and was probably looking for freshwater shrimp. Pollution and habitat loss are two factors that have led to the Otter's decline in the last few years. THESE VIDEOS ARE BETTER IF YOU MAXIMIZE YOUR SCREEN
The other rare mammal that we saw was the Greater Grison. These small mustelids (Weasel Family) run around the forest and are rarely seen by people. We are catching more of them on camera traps. We were fortunate to have a short video and a nice clear picture of one.
A Good Mother
It has also been a few years since we have captured good images/video of an Ocelot and her cub. From October through our last visit in March, we saw them on a regular basis in all parts of the forest. I compiled a short clip of their wanderings.

It was just a matter of time...When we started this project years ago, Aida told us that it was not uncommon to see naked people out in the woods. Sure enough, we got several video clips of an amorous encounter of this gentleman and his lady friend!

We teamed up with Osa Conservation for the largest Camera Trap project in Central America. They created a grid with 120 squares(240 cameras, 1,920 AA batteries) over the Osa Region of the Golfo Dulce. Each Square has two opposing cameras. The study will run for 90 days.

We have also been working with Osa Conservation for almost two years to get wireless cameras working out in the Osa Peninsula near Corcovado National park. They finally received a wireless network out there. I was apparently able to crack the code in order to get their network up and running. We had some great help from a new wireless camera company called Barn Owl. It seems as if it is only matter of time before we get images of a Jaguar!
|Capuchin Monkey and an ancient sphere.|
We were presented with an opportunity to visit a site literally right down the road from Ocho Verde where several of these spheres are located. We placed a wireless camera on the property and mysteriously the 12 new lithium batteries died before one photo could be taken. I eventually moved it to another spot where it seems to be functioning. It is sending about 60% of its pictures.
I put one of our trusty white flash cameras down by the creek and got some outstanding images.

What in the hell is it?Our cameras take great pictures, but sometimes we just cannot figure out exactly what is going on. We have two cases that we would like to share here. The first is this strange apparent beam of light shooting across the frame. It could be an insect, but at 5:36 am it is pretty dark at this place.
|Shutter speed is 1/122 of a second.|
|Whatever it is seems to be traveling very fast.|
The second mystery image involved what I think is a rather large animal.
|1:20am in the center right of frame.|
|Mystery animal for sure.|
If you have a guess on that these are, please email me or leave a comment below. Thanks.
