Boomslang is known to raid bird nests and their diet includes birds and their eggs (e.g. Buys and Buys 1983; Marais 1992; Branch 1998; Clauss and Clauss 2002; Spawls et al. 2006; Alexander and Marais 2007) although there is a paucity of published sightings regarding specific bird species as prey. On 2 December 2018 we observed an adult Boomslang Dispholidus typus viridis individual (see Figs 1 and 2) exiting a white-browed sparrow-weaver Plocepasser mahali nest. The nest was part of an 11 nest colony in a purple-pod terminalia Terminalia prunioides tree at 08h50 at the Andoni picnic site in the Etosha National Park (18°33’31.5”S & 16°48’29.2”E; 1090m). The Boomslang was vocally harassed and mobbed by the white-browed sparrow-weavers whilst exiting one of the nests. It settled on branches approximately 3 m from the closest nest, and a similar distance above ground level, where it struck at the offending birds a few times after which it was left alone. As the snake did not show typical signs of self-defence (e.g. inflated neck), it was assumed that it struck at the birds out of annoyance or even to capture one.
