... of inactivity, we collected the nest on 21 July, by cutting the palm frond at its base, and deposited the nest and supporting substrate in the collection of nests and eggs at the Museo de Zoología, CIBET, Universidad de Costa Rica, San José (MZUCR-AN-630). The nest showed no signs of weather damage or destruction by a predator or other animal (Fig. ...

... nest was of the low cup/base type (Fig. 2) sensu Simon & Pacheco (2005), and was built atop dry fern rhizomes accumulated by both adults on the palm frond rachis and supported by leaf petioles and leaflets ( Figs. 1-2). The nest had two layers and a small 'tail' (Fig. 2). The external layer was composed of dry fern rhizomes and the internal layer of pieces of dry leaves and ...
