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.”
—Prof Aliza Le Roux,
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

The University of the Free State’s (UFS) Vice-Rector: Research, Prof Corli Witthuhn, hosted a Research Celebration, at which the new National Research Foundation (NRF) ratings, presentation of the UFS Book Prize and the research support award were announced. The UFS Chancellor, Dr Khotso Mokhele, and Chairperson of the UFS Council, Mr Willem Louw, were in attendance among academics and staff members. 

An astounding preface
Presenting the opening remarks, UFS Vice-Chancellor and Rector, Prof Francis Petersen, congratulated all researchers and prize recipients on behalf of the rectorate. He applauded all researchers who had put their best foot forward and were acknowledged by the NRF. Furthermore, Prof Petersen said that the success of UFS researchers informed that the university received international recognition. “Research has the ability to play an active role in transformative action that leads to change. We are striving to be a leader in research output,” said Prof Petersen.

Humble and gracious recipient
Prof Fanie Snyman, Dean of the Faculty of Theology, walked away with the most sought-after award of the day, the UFS Book Prize for Distinguished Scholarship, for his book, Malachi, on the last book of the Old Testament. The book was published in Germany and can be used by theology scholars and academics.

“I have no words, I am sincerely grateful for this award, but I must also thank the university. I am grateful for the support that has enabled me to complete the book and achieve this award,” said Prof Snyman. He is the third academic to be awarded this prize.

University reaches new heights
The university’s new NRF-ratings were celebrated. The UFS has 27 new rated researchers and seven researcher’s ratings were renewed. Prof Jonathan Jansen received a NRF A-rating and Dr Daniel Spence a P-rating.

The Directorate of Research Development’s Eleanor van der Westhuizen was awarded the Research Support Award, which is to acknowledge those who accelerate and propel research and/or researchers.
