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

Bat Species of Ibera

 

The Esteros del Ibera is a vast, relatively undiscovered wetland and to my knowledge little study has been done on its bats species and certainly none in the northern gateway known as Cambyreta.  

Due to the amount of water and thus insects, it is a paradise for insectivorous bats.  Limitations are the amount of available roosts as there are few buildings and the trees are generally shorter than 15m.  It is likely that bats come to hunt in the area from some of the small towns and villages around the wetlands.  We also have an abundance of native fruit which should attract fruit eating species.

However we have found some tree roosts and the two houses, cabana and shed at the reserve are teeming with bats - mostly Molossus temminckii or Dwarf Dog-faced Bat.

We are embarking on a new bat call library for Cambyreta and for this we need many bat recordings.  We have already recorded around 16 different species of bat around the houses but need to do some long-term static recording at more remote areas so we can get a broader picture of our species.

The conditions in Ibera are ideal for the family Noctilionidae which are known as the fishing Bats.  We saw Noctilio albiventris flying low over our laguna a couple of years ago.  It hunts in a similar manner to the European Daubenton's Bat catching insects over the surface of the water.  At times it may also take small fish.  We have recordings of this species and its larger cousin, Noctilio leporinus, from another location in Corrientes but we are sure that it exists in the Ibera park, especially close to the larger lakes.

We are also involved in capturing bats for ID and biometrics and now have some high end equipment including 2 Harp traps, 1 triple high set up as well as a double high, hand nets etc.

We have authorisation to conduct bat research in the Ibera provincial park and other provincial parks in the province and are awaiting authorisation to conduct research in the rest of Corrientes.  We are also working with Cesar Bracamonte in research into Argentine bats and are in the process of producing a book with photographs of the national bats.

The following photos are of bats we have caught, measured, identified, photographed, recorded and released over the past three years.
