Ouberg ringing

Ringing on Ouberg Private Nature Reserve, 21-25 October 2020

Ouberg farm houses

 

The BDI held a biobash on  Ouberg Private Nature Reserve, a karoo farm near Montagu. A group of citizen scientists searched for birds, scorpions, dragonflies, and other fauna to submit photos to the UCT Virtual Museum.

Ringing was done daily around the farm house to help survey the birds, and to help train Karis and Salome. A total of 164 birds of 35 species were ringed and 17 birds were recaptured on days subsequent to the ringing date.

Top species were the Southern Masked-Weaver (25) and Cape White-eye (22). At least one of all 3 South African mousebird species were ringed. Two species, Cardinal Woodpecker and Pin-tailed Whydah, may have been missed on this trip if they had not been caught in the nets (although recorded on the farm previously).

Some other special catches were Acacia Pied Barbet, Pearl-breasted Swallow, Chestnut-vented Tit-Babbler and Fairy Flycatcher.

Breeding

Red-winged Starlings preparing millipedes for their chicks

 

23 species had at least one bird with a brood patch, showing a high degree of breeding after some good rain in the area. A Red-winged Starling nest on the stoep had 3 large nestlings which were ringed. They were well fed and it we observed the parents bringing beetles, millipedes, berries, etc. A Rock Martin pair had a nest in the garage, containing 2 eggs and 2 new chicks – these were inexplicably found on the ground far from the nest early one morning. After placing them back, they were still being tended by the parents. One Southern Masked Weaver colony had three nests form which chicks probably recently fledged successfully.
