Besides using thorny trees, what is another common location strategy employed by certain riparian weaver species?
Answer
Building over water to hinder ground predators.
Weaver birds demonstrate sophisticated site analysis in addition to their building skills, often choosing geographies that passively enhance the nest's defense. For species inhabiting riparian zones (areas alongside water bodies), a frequently observed strategy involves constructing their nests so that they hang directly over water. This placement acts as a natural supplementary barrier, as it physically prevents terrestrial or climbing predators from reaching the base of the anchoring branch or the nest itself from below, thereby augmenting the security already provided by the woven entrance tube.
