In April 2017 in Limón province, Costa Rica, a male and female built a nest in a hanging flower pot containing a fern, 2 m above the ground outside a house.
At the flower-pot nest in Limón, both adults carried green moss, fine fibres, rootlets and spider web, using fern rachises to support the nest. On 29 May 2017, a fledgling was seen on a garden shrub 2 m from the nest.
