A new order of amphibian, a very smelly entrance and our youngest ever volunteer!

“I’m not sure what this is but it’s, long, slimy and looks like it’s got two heads”. Well that got my attention! “Don’t move and don’t let it escape, we’re on our way” I replied racing to the car. We arrived to find that Maria’s description wasn’t so far from the creature we were looking at. About half a meter long and looking like a huge black earthworm we were delighted to find our first caecilian in the reserve. If this means nothing to you don’t worry, caecilians are a little known fossorial amphibian that spend most of their time underground so are fairly understudied. If you can’t quite visualise it, check out the photos on www.faunaparaguay.com/siphonopspaulensis.html This was a great find and a really interesting addition to the collection. Well done to Kjell who spotted it. Kjell was a volunteer from Belgium who joined us for 3 days with his mother Lieve, and sister Keri. It’s the first time we have had a family volunteer with us and it was great to be able to offer this opportunity for them to all do some fieldwork together. While they were here we had the traps running so they joined me in checking them and on their second morning they went to look for the capuchins – and stayed with the troupe for about an hour! Although they were the first family we’ve hosted, already they’re not the last! The day we dropped them off we collected a family of five. Mick and Kath joined us with Tilly (15), Ned (13) and Tristen (2). Hosting a family with under 18s was a real experiment for us because we’re not an ecotourism project and so we were a little concerned there wouldn’t be enough appropriate activities for them all to get involved in. However as soon as they arrived it was clear this wasn’t going to be a problem. These guys are amazing; by the end of day 2 we had already dug in a new pitfall trap line (in record time I might add!) and even little Tristen was put to work handing out pieces of string! And they enjoyed their stay with us so much they extended their visit and are now undertaking a mini project on bat roosting sites in the reserve. It has been great hosting both families here and we have been so impressed by how everyone has got really stuck in. In addition to our families, we are pleased to welcome 2 new interns to Laguna Blanca. Nick and Noah are from The Netherlands and will be with us for 3 months to undertake a research project on opossums (which as you may know is of particular interest to me). It has to be said they get the prize for the smelliest entrance. They arrived with a dead crab eating fox that they found on the road to Santa Rosa! Unfortunately the skin was too damaged to prepare as a specimen for the museum, however now that we have the beetles we can collect the bones and have a full skeleton for the collection. It is currently buried in the garden and in a few months time we’ll exhume it and feed the bones to our dermestid beetles who will clean them without causing any damage. Welcome Nick and Noah and thanks for that unusual present! For those of you who have been following this blog you will have heard about the burrowing owls. Well these guys are still about but we now also have a new neighbour. There is a beautiful American Kestrel that has taken up residency somewhere in the garden and doesn’t seem in the slightest perturbed by a house full of noisy volunteers! Another exciting bird that we are hoping will stick around is the Chestnut-eared Araçari. On two consecutive days last week we saw a group of three around the museum and volunteer house. These relatives of the toucan are a really spectacular sight and the fact that they are becoming more at ease with people could be a sign that the reserve is doing its job and that hunting pressure is being relieved. And finally some lovely news from the capuchin project, Maria was out with them in the morning and managed to get a really clear sighting of a female with a newborn. This is fantastic news as not only are they breeding in the reserve but they are also allowing our researchers to get close enough to see them - a great step forward in our habituation of the group. Thanks for reading folks, see you next time Helen

Hellos, Goodbyes, Felines, Lizard Tails and Hope for the Anaconda!

Hello everyone,

Firstly we’ve had to say goodbye to Jess and Dave, our Australian volunteers who joined us for a week, but not before they worked wonders around the reserve. What with those two, the Irish girls and not to mention all of the other volunteers and interns we have here, we got a remarkable amount done in the space of just one week. Last week we; built a second compost bin for the garden, created a horse proof fence for one of my pitfall trap lines, repaired all of the damaged pitfall traps, gathered, cut and placed tins out for snake traps, wired up a booster so we now get the internet at the volunteer house, dug in traps for Augusta’s Clyomys project and all took a trip down memory lane with David Bowie’s Labyrinth! And this was on top of having two trapping arrays open and running and everyone else’s projects too. Ten points for effort to all of our wonderful volunteers!

Dropping off Jess and Dave in Santa Rosa didn’t mean we were two volunteers down though, on the contrary as soon as we said goodbye to them we immediately picked up three more! Davina and Scratch are from the UK and decided to join us for a week as part of their tour of South America (the third group of volunteers to do this in as many weeks - word is clearly getting out!). Declan, our third arrival, is also from the UK and is here for 3 months to do an internship. He probably has the sexiest project to date as he will be responsible for systematically camera trapping the reserve. (And yes it is ok to be green with envy – I am!). If that wasn’t enough not only does he have this fantastic project but in his pilot run he caught a small feline on one of his traps!!! This is a very significant find, as it proves there are still felines in the reserve and opens up numerous opportunities for further study.

Shortly after these volunteer’s arrival we collected Rich; another intern who will be with us for four months. Rich’s project is of particular interest to me as he undertaking a behavioural study on the Microteiid lizards I have been catching in my pitfall traps on a regular basis. I have been trying to get his project off the ground myself for about six months and intend it to be a long-term large-scale investigation, but I simply haven’t had the time to get it started. Rich is also pleased that his project is of such importance to PLT as his results should pave the way for further investigation into these lizards. A classic example of how important volunteers and interns are to PLT, we simply couldn’t do what we do without them!

Although we have been saying hello to all our new volunteers we have also had some farewells to say too. JP our amazing lepidoptera and herpetofauna volunteer has finished his stay here and is heading back to the UK this weekend. JP was an absolute star and a pleasure to have around the camp and we will certainly miss him coming running into the house with “something interesting” in his hand - an amphisbaena for example! JP did wonders with our herp and lepidoptera collection; he collected 16 specimens of reptiles and literally hundreds of butterflies and moths. I know that he won’t want to accept all the credit for this though as he had our three Irish volunteers, Emma, Laura and Yvonne helping him to set, catalogue and display all of the butterflies he collected. We would have had a real backlog of specimens in the freezer if it wasn’t for these three and their sheer determination to get this job done. Thank you so much to all four of them for the excellent work they did with this collection. And after a three week stay the girls left Laguna Blanca alongside JP – if you remember from last time they arrived only planning to stay for three 3 days!

Now, we had a very interesting report last weekend and we are tentatively optimistic that we may have anaconda in the reserve. An Australian tourist was out walking one of our trails Mboijagua (which actually means anaconda in Guaraní) when he saw an extremely large, yellow snake; in actual fact he saw two! If they were anaconda they would have been juveniles but based on his description there is no other snake it could have been. We can’t base too much on this at this stage but if they are there we feel it will only be a matter of time before someone sees them again. Cameras at the ready people!

And finally autumn is creeping in here at Laguna Blanca, the nights are getting cooler and the nocturnal noises are abating. The small mammals seem to be getting more active too which is making our surveys more interesting and I have been catching opossums on a daily basis in my traps. It will be interesting to see what else appears now the seasons are changing.

And I think that is all I have to tell you about this time, such an amazing fortnight with a great bunch of people. I wonder what the next 2 weeks will bring…

Chauuuuuuuu

A house full of wonderful people, St Paddy’s day and here’s to another great year!

It’s all go again here at PLT. We have had an influx of new volunteers. First to arrive were Emma, Yvonne and Laura from Ireland who are stopping off with us during their trip around South America. They had planned to come for 3 days but having been here for a week they have now booked on for another 2! (Be warned readers, Laguna Blanca has this effect on people!). Shortly after the girls arrival, Maria joined us, coincidently also from Ireland. Maria is here on one of the volunteerships and will be assisting Jonny in studying the capuchins in the Atlantic Forest. And our 3rd arrivals were Dave and Jess from Australia who are also touring South America. They have been here a couple of days and already have done wonders with my garden (and know what they are doing too which is more than I can say for myself!)

Everyone’s arrival could not have been better timed as they were all here for St Patrick’s Day. Needless to say with Paddy’s day being so big in Ireland it wasn’t long before a table of events had been drawn up for the day which included a “donkey” derby, the inaugural Laguna Blanca St Paddies Day Parade and a enactment of the banishing of snakes from Ireland! The president of Ireland was invited to participate in a Skype link up but due to other commitments on this very important day was unable to accept our offer. But, according to his secretary, he thanked us for the invitation and wished us well for the day.

We had a real turn up for the books a few days ago too. While I was off site Karina and JP were handed a rattlesnake in a bag by one of the local people. This may not sound like much (and probably isn’t everyone’s idea of a gift!) but the point is it was alive and unscathed. Normally these docile snakes are killed at first sight due to the fear they instil in the local people here (which, let’s face it is not unreasonable as they do have an extremely potent venom). However this one had been brought to us so we could release it back into the reserve. This is such a great achievement and if we can turn this into the norm we could save a lot of snakes here in this area.

And finally today is the 1year anniversary of me leaving the UK to come to Laguna Blanca. It has been such an amazing experience I don’t know if it is possible to even begin to list the highlights. I have met so many wonderful volunteers, learned so many new skills and watched this project develop so much over the last 12 months. Thank you to all the amazing volunteers who have made it what it was. I am really so proud to be part of this fantastic project and can’t wait to see what the next 12 months have in store!

Until next time

Amphisbaenas bite! (Luckily the coral snake didn’t!)

Yes you guessed it guys, we caught another amphisbaena and yes it was me that got bitten! They look so docile with their little dog-like faces and tiny eyes, who would have thought that actually they have a very strong beak and aren’t afraid to use it? I now have two holes in one of my fingers where it drew blood. Actually it wasn’t very painful but was pretty amusing as it bit in and I couldn’t get it off. Being doubled over with laughter with a 40cm amphisbaena attached to your finger is not conducive to getting it photographed and back in the bag! Fortunately we know that they are not venomous but it was worth cleaning the wound with antiseptic once I finally managed to unhook it! (And yes typically I had an audience for the whole event!)

One thing I am really glad didn’t bite me was the coral snake JP found in the Atlantic forest. JP is a volunteer who joined us a week or so ago and shares my passion for herps. He is unstoppable and is always off hunting for snakes (or running around after butterflies – his other passion). Normally we don’t allow volunteers to go snake hunting on their own as it can be pretty difficult to identify a lot of them in the field. However JP has a vast amount of experience in snake surveying back home in South Africa and knows what to bag and what to leave well alone. So you are probably wondering why, if he is this experienced, he brought back one of the deadliest snakes we have in the reserve. The reason was that it wasn’t actually a coral snake. It was a mimic. The coral snakes we have here are a very brightly red with black and yellow stripes. The mimics are also these colours, but there are some subtle yet significant differences. The corals have virtually no neck and their head is not unlike a sausage, whereas the mimics have a clearly defined head and neck which makes them a touch prettier, (in my opinion at least). The markings are also much more fuzzy on the mimics where as the banding is clearly defined on the true corals. And, should you be confident enough to check their bellies (!) the bands stop on the underside of mimics whereas the true corals have complete banding across their ventral side. JP’s ability to correctly identify the snake he found meant that not only did he avoid handling an extremely venomous animal but he was also able to bring us another specimen for the museum. Good work JP.

This last fortnight has also been a sad one for us as we have had to say goodbye to two wonderful long term volunteers. Becky has now completed her research here and has left to spend a month exploring South America (very bravely on her own) and according to her last email she is currently freezing in Peru! Gemma our botany volunteer from Australia has also finished her work and is heading back to Australia in a few days time after taking in some of the museums and culture Asunción has to offer. It was great fun having them here and now they are gone the male to female ratio has switched and it’s just me and Augusta in the house with 3 boys!!! More girls please!

The burrowing owls are all doing well but are spending less and less time with us these days. We thought they had flown the nest (or burrow I should say) a few days ago but then they reappeared again. We are all bracing ourselves for the day they don’t return. However this is a happy/sad event. Happy, that all 5 have made it to adulthood and such a privilege for us to have them living so close to us, but obviously sad for us as we have become so attached to them. Good luck to the burrowing owls hopefully one will return with a mate next season to occupy the burrow again.

And finally if you want to see for yourself what Laguna Blanca looks like and who we are why not check out our new youtube channel http://www.youtube.com/user/ParaLaTierra. Admittedly most of the posts are of me getting very excited about the animals we catch here but I am trying to persuade more of the volunteers to get involved and talk about their projects on camera. They are still a little shy though! So apologies that it is a bit “Helen heavy” at the moment but I hope it will give you a taste of what we are up to and who knows might even persuade you to come out here and volunteer with us ;O)

Thanks for reading folks, until next time

Introducing Carlos

Hi All,

I wanted to take the opportunity to introduce myself. My name is Carlos and I’ll be working at PLT Ecological Station under the title of Research Scientist and Intern Coordinator.
I’ve only been here for a few days and I’m amazed at the natural beauty of this place. The people here are certainly special, including those associated with PLT in a staff/volunteer/intern quality as well as the locals in and around Laguna Blanca. Paraguay is certainly an interesting and poorly-known country and provides a unique experience which I doubt you’ll find in any other South American country.

The reserve itself has the potential to support a wide-range of projects in biology/ecology, physical (and even human) geography, due to the different biotopes present within it. In the few days that I’ve been here I’ve become familiarized with at least 7 different types of habitats representing both aquatic and terrestrial systems.

In addition to helping interns and volunteers with their projects, I’ll also be carrying my own research and I’m planning to set up a research project involving aquatic systems present at the reserve. Laguna Blanca provides the opportunity for the study of both lentic and lotic systems. The Lake is certainly an interesting system and is the source of a stream that runs beyond the boundaries of the reserve. There are additional riverine systems nearby which might be useful for replication. More specifically, I’m planning to study the invertebrate community of the lake and stream and its association to different physico-chemical parameters.

I already started doing some Geographical Information System (GIS) work, mapping the different habitats present at the reserve. In this context, Laguna Blanca is also a good place for those interested in honing their GIS skills as part of their project or even basing their entire project in the application of GIS techniques.

Evidently, terrestrial and transitional environments also interest me and I’m very looking forwards to establish projects in these systems and work with individuals interested in them.

I’ll discuss this further in the near future.

I’ll be writing regularly in this blog so keep reading for updates on life in this amazing place and how our research efforts fare!

Cheers,
Carlos.
----------------------------------------------------------------------------------------------------------------------------------------
Hola,

Quería aprovechar esta oportunidad para presentarme. Sé que generalmente en este Blog no sé que escribe en Castellano, pero a partir de ahora va a ser más común. Mi nombre es Carlos y estaré por los siguientes meses trabajando con PLT como Investigador y Coordinador de Pasantes (Interns).

Solo he estado por pocos días acá en Laguna Blanca y la verdad que este lugar es una preciosidad. No solo eso, la gente acá es muy especial, incluyendo a los que están asociados con PLT en calidad de personal/voluntario/pasante, así como la gente autóctona alrededor de Laguna Blanca. Paraguay es un país muy interesante y muy poco conocido. Yo creo que pocos países en Sur América ofrecen una experiencia tan única en términos de cultura y belleza natural.

La reserva presenta una excelente base para desarrollar una cantidad variada de proyectos en diferentes campos incluyendo biología/ecología, geografía física (e incluso humana), gracias a la variedad de diferentes biotopos presentes en la misma. En los pocos días que he estado aquí me he familiarizado con 7 diferentes tipos de hábitats en la reserva incluyendo sistemas acuáticos y terrestres.

Además de ayudar a los pasantes y voluntarios con sus proyectos particulares, yo estaré desarrollando y poniendo en práctica mi propio proyecto(s). Estoy planeando hacer una serie de estudios en los sistemas acuáticos de la reserva. Laguna Blanca ofrece la oportunidad de estudiar sistemas loticos y lenticos y siendo más específico planeo estudiar la comunidad de invertebrados en el lago y el rio que se desprende del lago y va más allá de los límites de la reserva. Hay sistemas de ríos adicionales alrededor de la laguna que ofrecen la oportunidad de replicación. Por lo que veo los dos sistemas son muy interesantes y han recibido casi ninguna documentación en materia científica.

Ya he empezado a trabajar con Sistemas de Información Geográfico (SIG), mapeando los principales hábitats e información relevante sobre la reserva, en este contexto Laguna Blanca representa una buena oportunidad para aquellos que buscan poner en practica sus habilidades con SIG usándolo en su proyecto, o incluso desarrollando un proyecto orientado específicamente al uso de SIG.
Por supuesto, proyectos basados en sistemas terrestres son ciertamente interesantes y busco emprender proyectos en esta área y estaría encantado en ayudar a cualquier pasante interesado en el área. Este aspecto lo discutiré más por este medio en el futuro.

Yo estaré escribiendo regularmente en este blog así que estén pendientes para nueva información sobre investigación y como es la vida en este curioso lugar!

New records walking straight in the door

Actually to say “walking in the door” isn’t very accurate. Firstly because I am referring to 2 bats and an amphisbaena, neither of which walk! Secondly because we found the amphisbaena outside and the bats probably came in through the windows! What am I talking about? Maybe I should start at the beginning.

It was a few days ago that I was just settling down for bed when Jonny called out “Um Helen there’s a bat in my bedroom”
“That’s quite exciting” I thought and went over to the boy’s dorm to have a look. And sure enough there was a large bat with enormous ears sitting on the wall looking most perturbed. We decided the best course of action would be to try and catch it with a butterfly net and then transfer it into a pillow case, and low and behold we managed to bag it within about half a minute (another example of how easy things can be when there is no one around to witness it!). We waited until the next morning to identify it and were delighted to discover it was Lophostomia silvicolum; a new species for Laguna Blanca. Interestingly it is a high flying species (which probably explains why we haven’t caught it during our surveys) and has a preference for nesting in termite mounds. And, best of all, 3 days later we had another one fly into the house – I wonder if this species is like buses, can we expect a third?

However even more excitingly than the bats (or maybe I’m just biased because I love herps…) Karina caught a big fat amphisbaena by the water tank. Amphisbaenas are a type of fossorial lizard that have no limbs, scales over their eyes and move like an accordion. They are extremely difficult to survey as they spend so much time underground so this is a really great find for us. The one we found is one of the biggest species in Paraguay reaching up to 45cm in length!

I’m currently sitting at my window over looking the horse coral and I can see 4 of our burrowing owls all sitting in a row on the fence shaking the rain off their feathers and looking like they are quite enjoying the novelty of rain. They are getting so bold now; the other day one flew into our porch and grabbed a preying mantis from the light. Plus they are also learning to hoot now which is really rather sweet, especially as they are not quite there yet resulting in some rather amusing noises.

See you next time folks

A new wave of volunteers, fantastic foxes, a giant snake and an opossumarama!

Hi everyone,

It’s been all go here for the last couple of weeks; we have had a wave of new volunteers join us at Laguna Blanca. Augusta, Jonny and Marcela all arrived on the same day – the same bus in fact which is pretty impressive considering they were coming from the UK, Buenos Aires and Asunción! In the same week we also had a couple come all the way from the Czech Republic, Andrej and Katerina came for 5 days as part of their 2 week annual holiday. Needless to say they wanted to cram in as much as possible so we used their stay as a great opportunity for everyone to have a go at surveying as many taxa as possible. In those 5 days we went bird watching, smammal (small mammal) and reptile trapping, frogging and camera trapping. I think everyone’s highlight was frogging and it was great for me to have such a big group of interested people to show some of our amazing amphibians to.

Jonny, Augusta and Marcela are all here to volunteer on specific projects, Jonny will be taking the lead on our new capuchin project. Augusta is working on our long term study of Clyomys sp. out in the cerrado and Marcela is working on our Lepidoptera inventory. We were also fortunate enough to have Sergio with us to help get Marcela’s work off the ground. Sergio is an expert on Lepidoptera despite being only 22!

We have been having so much fun with our camera trap recently. One of the ways we are being most successful is by collecting all of our cooked kitchen scraps – that don’t go on the compost (the garden is coming along great by the way) and waiting a few days for it to get really smelly and then using it as bait. Not the most pleasant job it has to be admitted but very effective. We have some lovely shots of seriemas (an extremely elusive bird species that are similar to secretary birds from Africa), some great close ups of agoutis (like guinea pigs on stilts!) and most recently and most exciting a pair of crab eating foxes that you would almost think were showing off for the camera! We are placing it in a new location later today and we have some new ideas up our sleeves – I’ll let you know if they are a success...!

Do you ever have one of those moments when you do some thing really well and there is no one around to notice? Exactly that happened to me the other day when a massive black snake was in our kitchen. I wasn’t at all sure what it was but it couldn’t stay hiding behind the cereal cupboard so I decided to have a go at catching it in the hope that at best it would escape outside. However I managed to bag it straight away without any hassle or bother and was there anyone around to witness this amazing Steve Irwin moment? No of course not! Once I had a chance to cool it down a bit I got some photos and sent them over to Paul our scientific co-ordinator. Turns out it was a Hydrodynastes gigas, or false water cobra, a non-venomous but highly aggressive species. I wonder if I would have been so confident if I had known this before I tried to catch it!! It was however a new species for our inventory and so we took it as a specimen for the museum – when I eventually found something big enough to put it in!

And finally I am back out every morning checking my traps. This time however the target isn’t reptiles and amphibians it’s opossums. Because I keep finding new and exciting species for the reserve in my pitfall traps we have decided to step up the search and see if we can create a really comprehensive list of opossum species we have here. Therefore my trapping arrays have evolved from simple bucket traps to Sherman traps too. It’s a lot of work but I can’t pretend I don’t enjoy it and love being back out there at the crack of dawn! More more more!!!

And I think that is everything I had to tell you this time so until February

Hasta Luego

Helen
