Forgotten Species: the haunting whistle of the Anjouan scops-owl
December 03, 2009
Everyone knows the tiger, the panda, the blue whale, but what about the other five to thirty million species estimated to inhabit our Earth? Many of these marvelous, stunning, and rare species have received little attention from the media, conservation groups, and the public. This series is an attempt to give these 'forgotten species' some well-deserved attention.
The Anjouan-scops owl, native to Anjouan island apart of the Comoros island chain, is on the verge of extinction. It is so rare that for over a century it was believed to have already vanished.
"For a long time it was thought extinct, partly because its call is an unusual whistle which is unique among owls, but it was rediscovered in 1992 by Roger Safford of Birdlife International who was following reports of seabirds inland!" Hugh Doulton, the Comoros Project Coordinator for Bristol Conservation and the Science Foundation, told mongabay.com.
"Anjouan has an extremely high population density and with all agricultural land already under cultivation, the island suffered from one of the highest rates of deforestation in the world during the 1990s (fourth highest according to FAO)," Doulton explains. "This rapid destruction of its habitat likely puts the species under severe threat, although the lack of data means no one can be sure of the status."
Despite the fact that ornithologists have been aware of the owl for nearly two decades, the species remains almost a complete mystery. Basic information like the owl's preferred prey remains ripe for discovery.
"Since  there have been a few minor studies of the species, though there is still little known about its ecology or breeding habits, or even how many pairs are left," Doulton says.
While current population estimates range from 100 to 400 birds surviving on the island, Doulton hopes that new conservation surveys will determine just how many owls are left.
"As part of a wider forest conservation program run by Bristol Conservation and Science Foundation financed by the UK government's Darwin Initiative, we are doing the first ever thorough surveys of the species to obtain a good population estimate and a clear idea of its status," he explains. "This will allow us to elaborate conservation recommendations which, in addition to habitat protection, could include measures such as nest boxes in agroforestry areas."
While Doulton has never seen the Anjouan-scops owl, he has had the pleasure to listen to them: "I've heard them calling across the valley above the only lake on Anjouan. With a fire going in the evening, you can lie down and listen to the males and females duet to each other from one side of the valley to the other. Magical!"
There are many reasons to save a species on the brink of extinction, but sometimes the most powerful is simply that future generations deserve to inherit a world as 'magical' as the one we have. I hope one day little Harper Lostetter (and other owl-lovers) will be able to hear the Anjouan scops-owl's haunting and unusual whistle. I hope she will know then that humankind had made a conscious decision that preserving the world's species mattered beyond profit and utility. Sometimes just being an owl should be enough.
To help save the 'forgotten' Anjouan-scops owl: Contributions to conservation work for the Anjouan-scops owl can be made via Bristol Zoo Gardens, or by becoming a BirdLife Species Champion for the owl . BirdLife Species Champions is an innovative program where an individual, group, or company commits to funding conservation measures for three years for a Critically Endangered bird. Currently the Anjouan-scops owl does not have a champion.
Hugh Doulton runs a forest conservation program on the Comoros for Bristol Conservation and Science Foundation (www.bristolzoo.org.uk/conservation), working in partnership with Durrell Wildlife Trust, the University of East Anglia and Birdlife International. The work is financed by the UK Government's Darwin Initiative, Airbus, and the UK High Commission in Mauritius. Those interested in hearing more about the work or providing support can contact Hugh Doulton at email@example.com.

Forgotten species: Madagascar's water-loving mammal, the aquatic tenrec
(11/12/2009) There are many adjectives one could attach to the aquatic tenrec: rare, mysterious, elusive, one-of-a-kind, even adorable, though one tries to stray from such value-laden titles since it excludes so many other non-adorable inhabitants of the animal kingdom. This small and, yes, cute insectivore, also known as the web-footed tenrec, lives in Eastern Madagascar where at night it spends the majority of its time swimming and diving in fast-moving streams for insects and tadpoles. It sleeps during the day in small streamside burrows. To date that is about the extent of our knowledge of this species.
