We studied the breeding behavior of the Smoke-colored Pewee (Contopus fumigatus), a common inhabitant of montane South America, in northeastern Ecuador from 2001-2008. We found nine nests which were all active from September to December, suggesting a reproductive peak during the drier months. Nests were shallow mossy cups, lined with lichen and/or pale fibers, and saddled over a horizontal branch in clearings or forest edges. Mean nest height was 8.8 m and Alnus acuminate (Betulaceae) was used as a substrate most frequently. Clutch size was two eggs at four nests and eggs were white with sparse cinnamon and lavender markings. Only one adult, presumably the female, built the nest, incubated, and brooded. Brief observations during incubation suggest that eggs are covered for c. 67% of daylight hours. Both adults, however, fed the nestlings, sharing the work almost evenly and feeding nestlings a variety of aerial invertebrates, generally at rates of 3-10 feedings/h. At one nest, construction lasted c. 14 days; incubation period was 16 days; and the single nestling left the nest after 21 days. Accepted 5 September 2010.
