Strange Tails

We're delighted to have a strong population of strange-tailed tyrants at the reserve. So much so that we've adopted these beautiful and endangered birds as the symbol of the Trust

Respect Other Species

Thank you for visiting our website. We're a small trust dedicated to preserving endangered species and defending the habitats that are essential to their survival.

Our wildlife reserve is made up of 1,600 hectares (4,000 acres)  of grassland/wetland in north-east Argentina. We purchased this former cattle ranch in 2010 and have since worked constantly to restore its ecological balance and provide a safe, sustainable habitat for its magnificent flora and fauna.  We are primarily a research station and welcome visiting naturalists, biologists, ornithologists, Bat workers, licensed bird ringers and keen amateurs interested in conservation.  We are also after volunteers for the spring of 2016 (Sept - Nov)  See our page on Volunteering

Our Trust is also involved in Woodland Bat research in the island of Jersey, UK, where we have recently discovered a new species of bat for the island - Myotis alcathoe.

We have several photo galleries that we hope you will look at including 'Birds of Ibera',  (10 new bird species added during the past year), Mammals of Ibera,  Bat ID'Reptiles of Ibera', 'Endangered Species', 'Fauna of Iguazu' amongst others.  

Since April 2015 we have had an example of Crax fasciolata (Bare-faced Curassow) at our reserve.  From September onward we hope to start a breeding program with this species, which is the first in Corrientes for decades. Read more here for information on this Cracid which is highly endangered in Argentina.

                                  

                                 

We are just coming out of El Nino conditions and have had no rain for around 3 weeks.  There is a good chance of La Nina conditions which bring us drought so we are preparing ourselves by cutting anti-fire paths and doing some controlled burning.  We currently have a few Alectrurus risora (Strange-tailed Tyrant) but expect more to arrive in the Argentine spring..   We are planning to do a detailed study of this species next spring (Sept/Oct) and will be looking for volunteers to help us for with this and other projects.  We have the authorisation to do some ringing and will be making use of coloured rings to help us identify the individuals.  Thank you to Parques & Reservas for the authorisation.  

The small pond at the western end of our garden was so full that we had to construct a bridge of 70m to cross it without having to wade waist deep.  This pond dried up several times in 2011-2012 - one cannot imagine that to look at it now. See photo above and in Reserva Don Luis  Things are drying up a bit now and we face the possibliity of another drought though we are still very waterlogged at the moment.

The picture below is of a 7 Banded Armadillo, the smaller of the 2 Armadillo species that we have here.  We discovered this one in the garden near the houses.

We are currently involved in evaluating the bat species that inhabit this region which is known as the Esteros del Ibera or Ibera Marshes. Please look at our page on Identification of Bats. There is no official bat call library in Argentina so we are creating our own.    We have identified 16 different species from our recordings, some of which are relatively unknown here.  We have also spent some time mist netting for bats during the past few months which has resulted in six different species - Molossops temminckii. Eumops patagonicus, Molossus rufusLasiurus ega, Eptesicus furinalis and Myotis nigricans.   Finally we feel we are making some progress toward identifying our bat species in a country in which they generally persecute these specialised mammals. See the bats that we have identified on our Mammals of Ibera page.   

We also spent some time in the NW mountaineous province of Jujuy, working with bats in December 2015.  We captured several new species, most of which are also in our province of Corrientes, and we learnt a great deal from bat expert Cesar Bracamonte on techniques and ID.

This is the second largest wetland in South America and is renowned for its biodiversity, in particular amongst the bird species.  We have several endangered species at our reserve including the Maned Wolf, Marsh Deer, Neotropical Otter, Strange-tailed Tyrant, Marsh Seedeater, Greater Rhea and Ochre-breasted Pipit.  We have some scientific papers on our species and will be adding to these in the near future.   One of our volunteers completed a behavioural study of our Howler Monkeys and another collected data on our amphibian/reptile species.  We have also written a paper on the results of our woodland bird ringing week and will shortly be uploading the paper on our reintroduction project.

We have some exciting plans for reintroductions, initially of the Bare-faced Curassow where we have made a significant step in obtaining a male for the reserve.

This is very much a live site, with new content and photographs being added constantly.  We have just left the reserve after a short winter trip but will be back for another short trip in August.   We hope you'll enjoy your visit and that we'll be seeing you again.  Any queries please contact us at info@collett-trust.org
