Notes on the Nests, Eggs, Incubation Period, and Nestling Development ofThripadectes holostictus moderatus

Abstract

Thripadectes, a little studied genus in Funariidae has thorough nest descriptions for five of its seven species, most consisting of one or two nests. Although the nest of Thripadectes holostictus has been described, it is based only on two nests, and there is no nest description for the subspecies, T. h. moderatus, which we report in this study. Between October and December 2011, we monitored four nests of T. h. moderatus in Manu National Park, Peru. In addition to reporting the first nest for the subspecies T. h. moderatus, we provide new information for T. holostictus, including incubation period (between 13–17 days), fledgling period (20–23 days), fresh egg weights (x ¯ ± SE = 5.8 ± 0.1 g), nestling growth patterns, further evidence for biparental care, and new observations on nest materials.
