Spectacular mammal rediscovered after 113 years!

19 May 2011 | News story

A unique and mysterious guinea-pig-sized rodent, not seen since 1898 despite several organized searches, has bizarrely showed up at the front door of IUCN Member ProAves’ El Dorado Nature Reserve Eco-lodge in the Sierra Nevada de Santa Marta of Colombia.

The magnificent red-crested tree rat (Santamartamys rufodorsalis), stayed for almost two hours while two ProAves volunteers took the first ever photos of a creature the world thought would never be seen again.

The charming nocturnal rodent made his re-debut to the world at 9:30pm on 4 May at the El Dorado Nature Reserve in the Sierra Nevada. The reserve was established in 2005 by Fundación ProAves, Colombia’s foremost bird conservation organization, with support from American Bird Conservancy, World Land Trust-US, the U.S. Fish and Wildlife Service’s Neotropical Migratory Bird Conservation Act, Fundación Loro Parque and Conservation International.

The animal was rediscovered by Lizzie Noble and Simon McKeown - two volunteers with ProAves who are monitoring endangered amphibians. It posed for photographs - including close-ups - before calmly proceeding back to the forest.

"He just shuffled up the handrail near where we were sitting and seemed totally unperturbed by all the excitement he was causing. We are absolutely delighted to have rediscovered such a wonderful creature after just a month of volunteering with ProAves. Clearly the El Dorado Reserve has many more exciting discoveries awaiting," said Lizzie Noble from Godalming, England.

"We are so proud that our El Dorado Nature Reserve has provided a safe haven for this enigmatic little guy to survive. The discovery exemplifies why we buy forested properties known to be important for endangered wildlife yet at imminent risk of being destroyed. We are also proud that our volunteers made the discovery of the decade, and hope future eco-tourists will see the mammal at the reserve," said Lina Daza, Executive Director of ProAves.

"The El Dorado Nature Reserve represents the ultimate Noah’s Ark, protecting the last populations of many critically endangered and endemic flora and fauna; a living treasure trove like no other on earth," said Dr Paul Salaman, the scientist from the World Land Trust-US who confirmed the identity of the species.

"Had we not worked with our partners to establish this reserve, it is reasonable to believe this species would still remain something that was only talked about in science journals. Now we need to work with our partners to take steps to see that this species continues to be a part of our world," said George Fenwick, President of American Bird Conservancy.

The red-crested tree rat will now likely be designated as Critically Endangered under the IUCN Red List of Threatened Species. What is most concerning, however, is that much of the tree rat’s potential remaining range is inundated with introduced feral cats that prey on native fauna.

In 2005, Dr Louise Emmons of the Smithsonian Institution examined the only two specimens of the tree rat that exist. She identified a number of unique characteristics, and assigned the species to its own genus Santamartamys. It is 18 inches long from head to the tip of the tail and is distinguished by a mane-like band of reddish fur around its neck and a black and white tail.

The 2,000-acre El Dorado reserve is named after the legendary lost city of gold, and is internationally known as a unique destination for eco-tourists. It is situated in cloud forests at 5,900 feet, just two hours’ drive from the popular coastal tourist city of Santa Marta. The reserve and adjacent lands host the highest concentration of continental, range-restricted bird species found anywhere in the world, including the endangered Santa Marta Parakeet, Santa Marta Bush-Tyrant, and Santa Marta Sabrewing, all of which have their entire or major stronghold populations there. It also holds one of the highest concentrations of endemic and threatened amphibian species in the world. The reserve is listed as an Alliance for Zero Extinction (AZE) site, establishing it among the world’s highest priorities for conservation, yet remarkably little is known about the area.

This discovery marks the beginning of a major effort by ProAves and Global Wildlife Conservation to save the Red-crested Tree Rat.
