Strange Tails

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

The growing diversity of the animals of Reserva Don Luis is a fresh source of delight every time we return.  We don't play favourites, but it's impossible not to engage more with some of our more conspicuous guests.  One of these is the strange-tailed tyrant.  The male is stoic in his tolerance of one of nature's strangest - and it would seem least practical - adaptations.  He's willing to suffer to be beautiful, and somehow manages to fly with tail feathers that were surely designed for a bird three times his size.

We love his perseverance; his resolution to succeed against challenge, and his ability to prove that anything is possible.  He's appearing in growing numbers on the Reserva Do Luis, and his success has become an allegory for, and a symbol of, our own.

When we started the process of updating and redesigning our website, we wanted to adopt an image that symbolised our aims and our challenges.  This brave little flycatcher, with his indomitable character, was the perfect choice.

The logo is a stylised profile of a male tyrant, silhouetted against the sunrise.  We coloured the sun the blue of the Argentinian flag in honour of this country's beauty, its climate and the breathtaking span of magnificent animals that it nurtures.

Tadarida brasiliensis (Brazilian Free-tailed Bat)

Tadarida brasiliensis

Brazilian Free-tailed Bat

< Back

The Brazilian Free-tailed bat is part of the family Molossidae and is the most common bat in the Americas.

Strangely it is rare in our province of Corrientes but is found in almost all of the other provinces. We only captured this species in October 2019 at the reserve, probably in migration.

Its distinguishing feature is the wrinkled lips which is uses to make loud echolocation calls.  The ears are large and almost joined over the top of the head, fur is greyish with a lighter venter and it has a longish free tail.  They have long narrow wings which make them one of the fastest flying bats.
