Cost-effective defence policy (#16 in Namibia single-image series)

 

 

Many of Africa’s “acacias” – particularly those commonly known as thorn trees/bushes – have a great many very fierce thorns, designed to deter browsing animals.

Nesting birds – usually, one of the weavers – are undeterred, and the feathered home-builders also often get a “free kick” from those thorns.

Birds who nest in the thick of thorns are deploying the tree’s weapons to defend themselves (and their young) from bird-eating predators.
