2016 Update Number One ---> 3 New Animals Recorded UPDATED

Because you never know what will look into the camera.

Now that I have your attention.....

You may disregard that monkey above...yep...easier said than done.  That morning in mid-January when I clicked on what I though was a just another capuchin monkey video, only to discover this guy looking into the camera...  Yikes!  Well it was just one of 6000 images that we had to go through after leaving the camera for 5 plus months.   We were fortunate to see 3 new and rare species along with our usual mammal species.

Up the creek

The Gaea camera has been always been placed above the waterfall to capture animals that visited the creek.  The previous location, looking at the giant log, was replaced as the old log had decayed and washed away.  We see more strangers in this area than another, and this cache of images was no exception.  

Fortunately the guys with rifles only spent 4-5 minutes in this area before leaving empty handed.

Moments before these hunter passed by we had seen a paca go by, and an hour after the hunter left, the paca came by again.  So we were glad it was safe. 

We don't see many armadillos on the property, but we got a picture of these two enjoying the stream.

I by passed the next photo several times and considered deleting it since I saw no animal.  However, I did see something in the picture.

Several close up looks later, we determined that it was a very rare mammal that is seldom seen in camera traps.  It is a Greater Grison.  They are members of the weasel family and are very much like badgers.  They have a black mask beginning at their eyes which throws your perception off if you have never seen one before--and I had not.  Our friends over in the Osa peninsula got this handsome pair of Grisons last fall on his camera trap.

  Here is the close up of our Grison:

We have since placed a second camera up in this area to see if we can spot anymore Grison activity during the next few months.

Predation

We don't see much of it, but when we do it is pretty exciting.  In the nearly 100,000 images we have had over the last two and half years, we have only seen a handful of animals with prey: ocelot with a rice rat, the tayra with iguana, and many agoutis with nuts.  We were very interested when this image came via email from one of the wireless cameras and into the Instant Wild webpage in London.  It appeared to be a large raptor having a face off with a normally arboreal woolly possum.

The wireless camera records two pictures, but sends only the second image.  Here is what the first shot revealed:

It was a battle between the opossum and this raptor with yellow legs.  There were no more images of this from the wireless camera or the companion cameras nearby.  We do know that woolly opossums are very fierce when cornered.

Deadfall

One of the things that we have learned is that many animals like to use fallen trees a pathways through the forest.

Tamandua or ant eater on the prowl.

This observation has led us to aim more cameras towards fallen trees and vines to hopefully target animals more accurately.

Collateral Benefit

 

The above image is a collared peccary.  They have not seen peccaries above Golfito in many many years.  Even though the above image is not from our cameras, our project inspired this land owner/friend to place a camera trap in the forest behind their home.  This site is only 3.5 miles from our property.  There are not many corridors for peccaries to travel, but with Costa Rican ban on sport hunting, there is a chance the peccaries can cross the highway and continue to repopulate forested lands.

Mouse Opossum

The  second new species(for us) that we believe that we have caught on camera is another one of the arboreal opossums.  In addition to the woolly opossum there is a tiny Mouse opossum that we have had glimpses of coming down from trees. We hope to have some images up soon.

Long Tailed Cat

Finally, we can add another cat species to our list.  The Margay is more of a tree dweller than is the ocelot.  It is also a bit smaller and has a longer tail in respect to body size.  They do not adapt to habitat loss as well as the ocelot and need undisturbed forest.  We only have one clip from mid January and we have incorporated it into this short video on the cats we have seen the past 6 months.  The Margay shows up in the intro and again at the very end of the clip.  There are plenty of close ups of ocelots and you can really see how short their tails are compared to the tail of the Margay.
Maximize the screen size to see the video better.

  MARGAY UPDATE 2/27/16

The excitement of realizing that we do have a margay on the property, led me  to quickly look over some other ocelot pictures and videos.  I am often so consumed and focused on plowing through 4-5 months of images that I often pay little attention to what we actually record during our time in Costa Rica.  This was exactly the case with the video below:

Back in July during our visit, I downloaded this quick cat video and discounted it as a young ocelot.  The slight body and head, long tail and 'closed' rosettes actually make this a relatively easy ID.

Current Challenge

Operating a camera trap project this size alone is rewarding but challenging.  The countless hours spent looking through images, placing cameras amid mosquito and ant bites in sweltering heat, is certainly a labor of love.  What is most difficult is the financial challenge.  So far we have been fortunate in that camera failures have been mostly covered by warranty but our 2 year grace period on the original cameras is running out.  The cost of AA lithium batteries has continued to increase.  With the rare advantage of real time images sent from the wireless cameras, we now have data plan costs. Vamos Rental Cars in Costa Rica and HCO-Outdoors Cameras have been instrumental in helping to defray some ongoing costs of batteries and cameras.  Friends and family members help us a great deal as well in keeping our U.S. pets safe and well fed. Thanks to all of them.

If you would like to offer support to our project you can do so in several ways.  The easiest is by clicking on this paypal link:

You can also contact us via email at OchoVerde@gmail.com to receive mailing instructions for a personal check/supplies.

Finally,you can go to one of the online websites, Amazon or eBay to purchase AA Lithium batteries  directly from them and have them sent to our home in Charleston, SC. Contact us for the address.

Our images have become favorites across the globe via the Zoological Society of London's Instant Wild app and webpage!

Our next update will feature BIRDS in the camera traps!

Hello Instant Wild!

"They are going to stand right here"

My name is Frank.  My wife, Kate and I run the camera trap project in Costa Rica.  I'd really like to thank ZSL , Edge, and Instant Wild for allowing us to be part of such a great idea.  I thought that you may be interested in knowing a bit about camera trapping in the jungle, these particular wireless cameras, both camera trap locations, and finally about some of the animals.  We are currently in South Carolina in the United States and get our images via email seconds before they are posted on Instant Wild.

About the Ocho Verde Camera Trap Project

We acquired the property in 2010. It had been classified as a preserve by the original owner who was interested in maintaining a population of the Endangered Red-Backed Squirrel Monkeys. He did this by planting fruit trees in the cleared areas and allowing the secondary and primary jungle continue to develop.  He probably did know it at the time, but the squirrel monkeys actually do better in recovering secondary rainforest as opposed to primary rainforest.  Unfortunately when the property changed hands, the new owners soon lost interest in the property and the land was hunted for Pacas, Curassows, and Tinamous.  Even some of the large trees were slashed and 'milked' for a medicinal sap. When we arrived, we brought in a full time caretaker family who had a non violent way to curb trespassers and poachers.   

Prior to our first visit as property owners, Kate reached out to an now defunct organization called Yaguara who were camera trapping all over this part of Costa Rica. We could not offer much financial support to their organization, but we were able to transport 8 camera traps for them duty-free from the United States.  We even purchased a camera trap for ourselves.  On Christmas day 2010, we looked at the memory card and had a visit from an Ocelot.  That was exciting, but we wanted to find out what else lived on the property and were animals recovering from being poached.  In 2013, we launched and Indiegogo project that helped us buy 12 cameras that were spread throughout the property.  We learned about so much more. We learned patterns of activity, movements by individuals and that we had a great amount of biodiversity.

Camera Traps in the Jungle

If you have ever been to a tropical rainforest one thing that you will notice is that it is dark.  The thick canopy of trees obscures so much light that photography with a DSLR, point and shoot, or camera phone is a real challenge.  Most contemporary camera traps were designed to capture images of feeding deer and not see animals in the dark wet humid jungle. Those who know about photography realize that in low light you need long shutter speeds. Long shutter speeds give blurry images when there is movement.  That is one of the image conundrums we are faced with in dense jungle camera trap photography.

The ants are beginning to obscure the lens. (jaguarundi)

A few days later this was the last recognizable image. (raccoon)

We have some other problems being in the jungle.  Rain can get on lenses making for strange and blurry images.  Worse still, bad rubber seals allow water to actually enter into the cameras short circuits occur and render them useless.  Plants can grow very fast in the rainforest and often times a plant will grow smack in the middle of our frame.  This obscures animals and sends off false triggers that eventually drain batteries.  We also have problems with ants and spiders.  A species of tiny spider finds the little hood over the lens a perfect place to spin a web.  It is a nice and dry space, but the web obscures our view of all animals.  The ants will eat the rubber gasket where the camera door closes and lets water in.  They can also just invade the camera and eventually close off the viewing portal.  Cameras often quit working for no apparent reason and sometimes batteries inexplicably corrode.

About these Cameras

The Spartan Camera(showing adjustable antenna) and my iPhone 5 for scale.

Like all of the cameras that I have seen on Instant Wild, these are made by HCO Scoutguard.  They are called Spartan cameras. They were new in the Fall of 2014.  I don't have the ability to name the cameras on the images.  The cameras use infrared flash for night images.  There is not a white flash wireless camera on the market yet, but there will be in another month or so(fingers crossed).

The cameras use 2g (second generation) cellular technology.  There is currently 3g and 4g available.  We use Spanish telecom operator Movistar as our provider as it is the only one that is within range of the cameras as of now.  The Spartan can be set to send images via text or via email.  They are currently set to send email images.  

So what happens when an animal triggers the camera?  The camera records two images at 8mp to the internal SD card(see top image for a card saved sample).  The second image is then compressed into a small file and sent to me and the Instant Wild image address.  The Spartan can send larger images, but that will use slightly more battery power and twice as much data as the current images.  We opted for the small images as we were unsure of data costs and battery drain, but this can be adjusted in the future.

The cameras have a neat feature called SMS.  This gives one the ability to control different aspects of the camera by calling a number for the phone and then entering in commands via text.  One can tell the camera to take a picture and send it right a way or enter other email addresses, etc. We opted to turn off SMS control as we were told it would consume much more battery power.  We won't be back in Costa Rica for a few more months and want the batteries to last a long time. 

We have had these cameras running since the end of January.  They were a challenge to set up as they had to be programmed with a PC and we are Mac people.  Movistar had never heard of these remote cameras so we had to teach them about needing a sim card, but no phone plan as we were only going to be using data for email transmissions.  The cell signal can be spotty in Costa Rica. If the camera is ready to send an image and cannot get a signal it aborts the attempt to send after a few tries.  Fortunately, the images are held on the SD card for us to view later.

The M in the information strip tells us that the camera was MOTION activated as opposed to another type of trigger command.  The P5 tells us how much battery power is remaining in the cameras. P5 indicates full power.  It should drop to P4---->P1 as the batteries run down.  The current batteries are AA Lithium batteries(12 of them) that we put into the cameras on February 11. The info strip also tells us the current phase of the moon as well as time and date and temperature.

One of the cameras was purchased with funds from a donor and the other was generously offered to us by HCO Scoutguard. A note about the Spartan camera shown above.  The model pictured has a blackout screen over the infrared LED's.  The two cameras that we are using does not have the blackout screen.

About the Locations

Images from this camera arrive from OCHOVERDE

Images from this camera arrive from ochoverde.

We chose the locations for the cameras due to the sheer numbers of animals that passed through the jungle at these locations.  The only animals that we have not seen in these locations are the Neotropical River Otter, some of the birds, and the wrong people.  We learned that these areas are very good because people trails and animal trails intersect. For identification purposes we'll call each camera OV and ov.

The OV camera is at a spot that we call "Tigrillo Woods" since it was where we have seen the most ocelots(tigrillos).  In the upper right corner is part of a huge whorled vine known as 'mi favorite'.  'Mi favorite' is the favorite vine of our caretaker.  It can also be seen numerous time in the videos and images in our previous blogs.  As you may recall from the Instant Wild images, the animals usually cross right to left or vice-versa.  That is precisely how the person trail is oriented.  There several 'animal' trails here as well as you can see in this crude schematic:

There are 5 possible ways for animals to enter frame.

 I considered placing the camera on the tree to the far right, but it would have to look up the trail and is looking west.  Cameras in that spot in the past get rain drops on lenses and light flares from the sun.  The Spartan cameras have a bit of a telephoto lens, which I'm not a fan, that tends to compress the field of view.  Across the trail from the camera is a fairly steep embankment.  In actuality, the animals often walk over and climb onto that vine instead of going up the embankment.

The other location where camera ov is placed is called 'Tres Hermanas', three sisters.  The 3 large trees are the three sisters.  We have had cameras here for over 2 years and again it is a confluence of people and animal trails.  Last year the top of the tree above the buttress on the left fell and gave us this nice log.  This log actually gave us a new animal trail.  To the left side are the branches of the tree where many animals feed on lizards and insects, etc.  The camera is not there because of the intense rays of sunlight during most of the day which makes it difficult to see the animals.  Here is how the trails lay out in another of my crude schematics:

The camera location is on the tree marked C.

If the truth were told, I would have placed the camera on the trees(marked with red circles) on one or the other side of tree #1.  I did have it placed on the small tree between #1 and #2 and it gave us great images:

Current camera location is off frame on tree past the one on far right(female Curassow!)

The other camera location is one that we had a camera at for a long time as well.  It mostly recorded videos that you can see in other blogs.  Here is a decent screen capture of the view from that location--it is on the tree to the left of tree #1:

Camera ov is currently placed on the viny tree behind the anteater/tamandua.

Again, this spot gave us a nice wide viewing area.  So, why did I decide to place the camera where I did.  There are a couple of reasons.  The main one being that tree #2 is about to lose another huge section of trunk.  It looks to me as if it will fall directly on top of each of our other camera location options, when it does fall.  The second reason is that there is good evidence of animal activity on the trunk of the tree in our current frame.  We think as this tree decays, it could be a popular feeding spot.  ov very well could get smashed when sister #2 falls so we'll have to keep that in mind.

ochoverde UPDATE MARCH 17, 2015
It looks as if a large chunk of tree has fallen to the left of sister #1. 

Empty Images

I really dislike empty images.  There are several reasons for them.  The most common are that the animals are moving fast.  The Spartan are reported to have a 1.2 second trigger speed which is considered slow in the camera trap world, but given the other advancements, we'll give it a pass. There are not a lot of reasons for animals to be moving fast.  One is that it is chasing something or being chased.  Another is that the camera is triggered by a flying bird or bat.  It could be a Tayra which is always on the move.  Trees and leaves moving in the wind can trigger the camera.  Hot spots can trigger them as well.  A hot spot is an intense area of sunlight that heats up more than the rest of the area around it. A hot spot example is in one of the empty ov images above as well.  The animals can be just off frame and trigger the cameras. Sometimes it is a mystery trigger.  The woods at Ocho Verde are indeed mysterious with many strange unexplained happenings.  Check out our "Mystery Smoke" video: 

I have no idea what triggered this.  If it is a person smoking early in the morning in the jungle, the cameras all around missed him coming and going.   He also would have had to kneel or sit as the camera is just a foot or so off the ground. He then would have let the smoke drift into frame.  Spooky.
     
The best cure for being blanked completely are multiple or 'burst' images. The cameras are programmed to take two pictures about 1 second apart.  This is done to insure that we get at least one image.  Unfortunately, the Spartan is programmed to send the second image instead of the first image.  I would change that if I could. The good news is that our blank images will have a companion image to give another view of the animal or to see what triggered our camera.  We also have non-wireless cameras very close by.  I will be able to sync up the times and we will ID the missing animals and those we could not recognize in the Instant Wild images. We will just have to wait a while to find out for sure.
  

Identifying Animals
The internet is full of strange and wonderful pictures of people captured at exactly the wrong times.  The same is true of camera trap images.  Animals in weird positions can be tricky to recognize.  People routinely mis-identify tayras and jaguarundis.  They are close in size, color, habits, and movement.  It is often the slender tail that clearly separates the two animals in a cam trap image.  When ID'ing animals, the guides are great resources.   Pacas and Agoutis look a lot alike at certain times.  However, you rarely see Pacas during daylight or Agoutis in hard darkness. Sure there are exceptions, but it is not often. Knowing an animals habits is part of the identification process.

Often times when looking through images, I'll have a few "What the hell is that?" statements.  They are usually figured out in images before or after when we get another piece of the puzzle to add to the equation.  The wireless Spartans give us one chance at the moment. We have to go on animal behavior and physical characteristics.  Even then we can't always be sure.  Take this image from a few weeks ago:

 is it this Tayra on the same log...

 or this capuchin monkey on the same log?

Hard to say, right?  We are leaning toward capuchin monkey.
What about this image...

This could be a Tayra, Jaguarundi, or labrador.  However, we have never seen a lab on the property nor are they very common in our part of Costa Rica...let alone a well fed lab.  The Tayras on the property are pretty healthy. The thin tail suggests that it could be a Jaguarundi.  We won't know for sure until we see the second image or even other images from the companion cameras to the left and right of our Spartan.

Someone asked about ocelot recognition.  We are doing that along with some paca(side patterns) and tamandua(tail patterns).  To date we have followed Crooked Tale/Roi, a female ocelot and her cub Pizza slice.  We saw Pizza Slice on the OV camera last week.  Ocelot recognition is addressed in this blog from last year.

Thanks for reading this far.  I'll be waiting for the next click of the camera...just like you!
