OVER the years, keen birders of the Drakenstein Valley have been called upon to help count cranes, waterbirds, and yes, sometimes even crows.
Their help is once again needed, for the first National Pelican Counting Day on 16 and 17 October.
This effort will be taking place across the whole of Southern Africa. In South Africa, there are only two breeding sites for Great White Pelicans: Dassen Island in the Western Cape, and St Lucia Wetland in KZN.
Unlike the situation in most parts of the world, pelicans have increased in numbers in the Western Cape.
Other than in the breeding sites, these birds often gather for roosting and feeding in local vleis and small water bodies.
There are a number of farm dams around Paarl and Wellington that provide feeding places to these odd-looking birds.
Locally, pelicans are often seen at the Paarl Bird Sanctuary, an irrigation dam in Noord-Agter Paarl and many smaller farm dams in the area.
Marta de Ponte Machado, a UCT doctoral student who is researching pelicans, as well as Meyrick Bowker from the University of KwaZulu-Natal will use the data to further their work.
According to Marta, it is hoped that the total number of pelicans in Southern Africa will be counted twice a year.
This first count will take place while the pelicans are concentrated in their breeding localities. Another count is planned for April to June, when the birds disperse after the breeding season.
The base of the counts in South Africa will be the already established Coordinated Waterbird Counts (CWAC).
"Together with the biannual data retrieved by CWAC from the main South African water bodies, we will be able to reach an accurate total pelican count for the region, and to monitor population changes and trends," she says.
"We plan to assign a person (or more) to every vlei, dam, lake, pond, shore section or river where pelicans have been seen before," Marta explains.
"However, there are a percentage of sites where pelicans are seen frequently that do not belong to the CWAC network, and for these we need volunteers that would count pelicans on these dates."
"This ambitious project will only be successful with the help of a high number of volunteers," Marta believes.
"If the pelicans visit your farm or you plan a day out with your family, and you have a pair of binoculars and some time, you could make a very important contribution to this project."
The researchers are interested in data, which include an accurate account of the number of pelicans seen, the site with coordinates if possible, date and time of sighting, as well as the direction where they were moving to and from.
"We are also interested to know what the pelicans were doing when you spotted them," says Marta. "Were they preening, sleeping, eating or flying?"
Any ringed birds should also be noted, as it could provide valuable information about the age of a bird and its movements across Southern Africa.
If you see any rings, please annotate the colour, the leg the colour-ring is on, and if there is any visible letters engraved on the ring.
People who want to volunteer their time for this effort, is asked to contact Marta de Ponte Machado at mdeponte@adu.uct.ac.za, 082-408-6025, or 650-4549 (w). The data collected can also be sent to her. |
