摘要：Virtually nothing is known about the breeding biology of the Powerful Woodpecker (Campephilous pollens), an
uncommon resident of montane regions from Venezuela to Peru. Here we describe for the first time, the nest, eggs and
nestlings. Based on observations of two cavity nests from northeastern Ecuador we report an estimated incubation period
of at least 16 days and a nestling period of 34-37 days. Both adults incubated the eggs and cared for the young, but we did
not quantify the proportional investment of each sex. One nest successfully fledged a single young after laying a clutch of
two eggs. A second nest failed after the nestling died, possibly from the effects of falling ash from a nearby volcanic
eruption
