 These form the "ribs" of the structure, and the female oriole then weaves the basket around these ribs with fine strands of vegetation obtained from Heliconia and other forest plants.Nests are typically constructed 1.5 – 20 m above the ground, with nests in Heliconia usually around 3–4 m, and nests in woody tree species higher above ground.Nests are not conspicuously lined.
