Bird ringing at Nuwejaars Wetlands SMA : 12 to 16 April 2026

This was our 12th bird ringing expedition to the Nuwejaars Wetlands Special Management Area. We arrived into a wet and windy few days at the end of what had been an exceptionally dry and hot summer. Not the most conducive weather for bird ringing. The table shows we caught a total of 80 birds of 23 species. Click on the species in red to see the structured texts for them on the BDI website. A full list of the species with these texts is found here. 11 of the species are are illustrated below using photos taken during the expedition; the Malachite Sunbird got too

The photos are chosen to show aspects of the bird which are often best seen with the bird-in-the-hand. This is the privilege of being a ringer.

Spotted Eagle Owl. This is our first at the Nuwejaars Wetlands. The cumulative effort of the community of bird ringers has helped document the patterns of movement and survival of this owl.

The bright yellow pectoral tufts of the Malachite Sunbird are usually tucked away and are not often visible outside the breeding season. They are used for mate attraction displays.

Cape Weaver, and adult male with eyes the colour of marie biscuits. This the bill that accomplishes the daunting task of weaving a nest out of grass.

Prof Les Underhill was Director of the Animal Demography Unit (ADU) at the University of Cape Town from its start in 1991 until he retired. Although citizen science in biology is Les’s passion, his academic background is in mathematical statistics. He was awarded his PhD in abstract multivariate analyses in 1973 at UCT and what he likes to say about his PhD is that he solved a problem that no one has ever had. He soon grasped that this was not the field to which he wanted to devote his life, so he retrained himself as an applied statistician, solving real-world problems.
