    The Animal Demography Unit (ADU) launched the Coordinated Waterbird Counts (CWAC) project in 1992 as part South Africa’s commitment to International waterbird conservation. This is being done by means of a programme of regular mid-summer and mid-winter censuses at a large number of South African wetlands. Regular six-monthly counts are regarded as a minimum standard; however, we do encourage counters to survey their wetlands on a more regular basis as this provides more accurate data.  All the counts are conducted by volunteers; people and organisations with a passion for waterbird conservation. It is one of the largest and most successful citizen science programmes in Africa, providing much needed data for waterbird conservation around the world. Currently the project regularly monitors over 400 wetlands around the country, and furthermore curates waterbird data for over 600 sites. 

     

    Colour Rings on Swift Terns

    Swift Terns are one of the few locally-breeding seabirds whose numbers are increasing. To help understand the main factors driving the positive trend of this species, a team of researchers from the Percy FitzPatrick Institute of African Ornithology and the Animal Demography Unit at the University of Cape Town marked 500 Swift Terns chicks from Robben Island in April 2013 and 2014 with metal and individually engraved colour rings. In 2013 members of the public reported how these birds dispersed, providing information on the fledging success, survival and dispersal of juvenile Swift Terns, which were re-sighted from Namibia to the Eastern Cape. 

    Gathering dispersal records is a time consuming but important task that relies on assistance from volunteers across southern Africa. 

    Rings in 2014 are orange and yellow (with black text) and green and blue (with white text), and are engraved with an “A” followed by a letter and a number (e.g. AU2). Rings from 2013 are yellow and white (with black text) and green and blue (with white text), and bear a code of one letter and one number (e.g. U2).  The majority of the colour rings are top-down and all are on the right leg. Click here for more information on the rings.

    If you see any ringed birds please record their location as accurately as possible (ideally GPS), the date and time of sighting, ring colour, letters on the ring (if legible) and age class (juvenile or immature). If a bird is found dead, please also record the number of the metal ring. 

    Please send the information to Davide Gaglio: swift.terns@gmail.com

    Citizen Science Week : Saturday 8 March to Sunday 16 March

    Citizen Science Week 8-16 March

    Ultimately, the goal of all the data collection by the ADU's citizen scientists is to have an impact on biodiversity conservation. The wealth of data and information contributed by our citizen scientists, collated and curated at the ADU, and analysed by our students and staff and by many other people, has improved biodiversity conservation in southern Africa. Together we are making a difference! For the evidence of this have a look at this one-page article.

    The ADU's Citizen Science Week celebrates the participation and involvement of citizen scientists in building our digital biodiversity databases, totalling some 18 million records. The objective of our "Citizen Science Week" is to give all citizen scientists a chance to become a community with the objective of collecting and submitting as much biodiversity data in digital format as we are able during the week. Citizen Science Week runs from Saturday 8 March to Sunday 16 March, so it includes two weekends.
