I spent some time in Worcester, South Africa during Spring, 2012. There was very active bird life in a cluster of Fever Trees.
First image is a female Cape Sparrow on the nest, and the second is a Cape White Eye with a tasty morsel. The White Eye got this morsel by digging in the same nest where the Sparrow was breeding. Talk about community activity!
