Reproduction
The nest of this species was first described in 2003 based on two nests found in Manú National Park, Peru. The open cup-shaped nests were suspended 0.7 m and 1.0 m above the ground. They were constructed of black rhizomorphs and covered in dry leaves attached with spider silk. Each nest contained two eggs. These had a pinkish white background which was almost completely covered with dark purplish-red streaks. They measured 23 mm × 17 mm in the first nest and 24 mm × 20 mm in the second.References:
