"He just shuffled up the handrail near where we were sitting and seemed totally unperturbed by all the excitement he was causing," said Lizzie Noble, a British volunteer with Fundación ProAves a conservation group in Colombia focusing on birds.
The nocturnal rodent hung out for a couple hours, allowing Noble and another volunteer, Simon McKeown, to take photos. Noble and McKeown were there to monitor endangered amphibians, but on this night, at least, they found themselves captivated by a long-lost rodent.
Described as about the size of a guinea pig, the red-crested tree rat—or if that's not long enough for you: the red crested soft-furred spiny-rat—had only been known from two skins previously. But the species was odd enough to be given its own genus, Santamartamys.
With its long absence it's almost certain the species is quite rare, and researchers say they expect it will be listed by the IUCN Red List as is Critically Endangered. Already, the species is believed to be imperiled by feral cats.
Located in the Santa Marta mountain range, the 2,000 acre (809 hectare) El Dorado Nature Reserve, which was established by ProAves and other groups, has been the site of a number of remarkable incidents recently. In 2007 the Santa Marta screech owl (Otus gilesi) was discovered in the reserve—still undescribed by researchers—while last year the first ever photo of a living Santa Marta Sabrewing (Campylopterus phainopeplus), a hummingbird, was taken in the park. But the red-crested tree rat may be the biggest surprise yet.
"We are so proud that our El Dorado Nature Reserve has provided a safe haven for this enigmatic little guy to survive," said Lina Daza, Executive Director of ProAves. "The discovery exemplifies why we buy forested properties known to be important for endangered wildlife yet at imminent risk of being destroyed."
The reserve is home to a high number of endemic birds and amphibians, some globally threatened with extinction.
"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, a scientist with World Land Trust-US who confirmed the identity of the species.
ProAves established the El Dorado Nature Resevere in 2005 with support from American Bird Conservancy, World Land Trust-US, Fundación Loro Parque and Conservation International, and the US's Neotropical Migratory Bird Conservation Act.
"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," said George Fenwick, President of American Bird Conservancy. "Now we need to work with our partners to take steps to see that this species continues to be a part of our world,"
