The White-winged Flufftail, a highly endangered bird species, was spotted less than 70 km from the UFS Qwaqwa Campus, home of the Afromontane Research Unit (ARU). In collaboration with BirdLife South Africa, the ARU is conducting a study to find out if this species also made its home in the Golden Gate Highlands National Park.

This rare species has so far only been found at three sites in South Africa.


Study to benefit local community

One of the ARU’s goals is to undertake research that will benefit the local communities, including SANParks. Should it be confirmed that these rare birds are also found in the area, the status of the Golden Gate Highlands National Park in the Important Birding Area (IBA) directory is likely to increase.

Prof Aliza le Roux, Associate Professor in the Department of Zoology and Entomology on the Qwaqwa Campus of the University of the Free State (UFS) and affiliated to the ARU, is conducting the study. She is also involved in other wetland studies.

According to Prof Le Roux, it is very difficult to find the bird. In a study, Prof Le Roux, Dr Sandy-Lynn Steenhuisen (botanist in the Department of Plant Sciences), and Dr Ralph Clark (ARU Director) have been deploying song meters in a rolling grid in the wetland areas, recording all bird noises around dawn and dusk. This is a non-invasive method to record bird sounds and helps to maintain the health of wetlands.

With these song meters they are trying to create a soundscape of the wetlands, recording all the sounds of the area by changing the location of the song meters every two weeks to cover the entire 2 km-long wetland area. Soundscape ecology is a fairly new technique and could be an effective way of measuring wetland health in high-altitude settings.

“In contrast with camera traps, song meters do not need a direct line of sight to record the presence of a specific bird – it can pick up songs from 150 m away in all directions. Camera traps may, however, be useful for adding visual confirmation of any bird’s presence, which is useful for a species that has only been heard a few times. In fact, no recording of the White-winged Flufftail’s call is currently in the public domain,” says Dr Le Roux.


Collaboration with Japanese university

Using these recordings from the soundscape, the team identifies the different bird, frog, and insect sounds recorded. According to Prof Le Roux, they are fairly new to the process and she would like to learn more, specifically about the analysis of the song diversity. She is visiting researchers at the Okinawa Institute of Science and Technology (OIST) in Japan in early December to investigate the variety of tools available to effectively analyse terabytes of acoustic data. Researchers at OIST have done similar studies on soundscapes in Okinawa along an urban gradient, and their expertise as well as access to a supercomputer could boost this research significantly.

The Qwaqwa area is on the border of the White-winged Flufftail’s expected distribution range.

“Because they and their habitat are threatened,
we are not sure if they are in the area;
and whether they may only be here to breed.”

Associate Professor, UFS.


“If we find that they did make the park their home, they will be more protected, as the park is a conservation area.”


Grasslands

When you are deaf, you have to work very hard to join in the conversation
2014-09-11

 

Dr Magteld Smith

A researcher at the University of the Free State is part of an overseas audiological breakthrough, after receiving a newly developed cochlear implant processor.

Dr Magteld Smith, researcher at the University of the Free State’s Department of Otorhinolaryngology, is the first South African to receive the Rondo cochlear implant processor from Med-El in Austria, manufacturers of cochlear implants and audiology-assisting appliances.

In the field of cochlear implants, the Rondo device is very advanced in the sense that the single-unit device is wireless and easily adapts to the sound of various environments (i.e. nature, conference halls, planes and phones). It also enables the receiver of a cochlear implant to hear more than one sound at a time – something that wasn’t previously possible.

Dr Smith tells about the meaning of the device in just a short time: “For the first time I can take a walk with my dog and hear both our footsteps on the gravel of the dirt road. I can hear my own footsteps, as well as the chirping of three different birds. All at the same time.”

Dr Smith, who is currently devoting her research to the medical-social model of the global organisation, International Classification of Functioning, Disabilities and Health, as well as research in all fields of deafness, relates the anxiety, frustration and depression which formed part of her daily existence. It also complicated and undermined her academic participation.

“Deafness is very traumatic. When you are deaf, you have to work so much harder to compete in a hearing world and to join in the conversation. Because of your deafness you become anxious about misunderstandings in the workplace.”

Dr Smith is working hard and constantly not to take a back seat in the academy due to her deafness. On completion of the Hubert H. Humphrey Fellowship programme, she received a certificate signed by the American president, Barack Obama, and was named as one of the top three researchers among 400 researchers from 192 countries. Only two South Africans are selected every year by the American State and International Institute for Education. 
 
In June this year, she delivered a presentation of her work and research at the 13th International Conference on Cochlear Implants in Munich, Germany. In July this year, she delivered a presentation at the 5th International Conference for Global Hearing Health. In August she was awarded a scholarship from the Golden Key International Honour Society for outstanding scholastic proficiency and academic merit.

“As a child, my parents were told that I was ineducably disabled. Today, I am grateful for the endless speech therapy since my toddler days, and to my dear mother, Jo, and late father, Chris Boshoff, and their firm belief in God which made them believe in me as a person with a congenital deafness. I am grateful for their unconditional love, endless patience, encouragement and support through my long journey in a competitive hearing world. This, together with the help of technology, enabled me to make a significant contribution to the academic world. Everything in my life is undeserved grace, pure kindness.”
