, HFG observed an adult spinetail carrying food to a nest at the Ecuadorian locality described above. Three days later, while examining the nest, a single fledgling flew from its entrance and disappeared into a nearby tangle of vegetation. On 24 February he collected the nest and made the following observations. The nest was an enclosed, globular mass of dry vegetative material, entered via a laterally oriented tube, and sited
cane and many smaller stems and leaf blades. Overall, the nest was 300 Although a photo on Wikiaves illustrates a nest, also found on an island in the Madeira in December (
