On Friday we did something I’ve been wanting to do for a while – we headed out to Mt Moreland (just outside of Durban) and watched the barn swallows congregate around Lake Victoria and then swoop down to roost in the reedbeds of the lake. They join up in large groups and circle around the lake for about half an hour before descending en masse to the reeds. It was quite spectacular. Not sure of the exact number of swallows but they were in their thousands.
We had some friends visiting from Ireland and, coincidentally, there was an Irish film crew there who are planning to follow the swallows back to Europe.
