The pink-legged graveteiro is a highly acrobatic bird, with a tendency to hang upside-down under the canopies of trees where it creeps along branches in search of its next meal (3). The diet of the pink-legged graveteiro mainly comprises beetles (2), but it also takes termites, moths, ants, insect larvae, insect eggs, spiders and other arthropods (3).
Both the male and female pink-legged graveteiro contribute to the construction of quite remarkable and conspicuous nests, which are easily visible from the roadside in the tops of mostly leafless trees (6). Each nest has an entrance corridor of varying lengths, made from woven sticks, which leads to a single ‘incubation chamber’ that is heavily lined with leaves and moss. The outer layer is carefully woven with twigs and the entire assemblage has been known to measure between 24 and 45 centimetres (6).
Even more notably, it has been found that the pink-legged graveteiro makes up to five of these astonishing constructions within a single tree, but only one is active (6). The others are thought to be “dummy” nests, used to confuse predators and parasites, but they may also serve as places to store nest construction materials (6).
The pink-legged graveteiro has been recorded breeding between September and October (2). Within the nest, both the male and female play a role in the feeding of the two to three young (3). However, immature individuals have also been observed helping with this duty, along with performing some repairs around the nest. This is a behaviour seldom seen in other species of the Furnariidae (ovenbird) family (6).
