Scytalopus, the largest genus of tapaculos (Family: Rhinocryptidae) typically build mossy globular nests within bank or tree cavities. Only 23 of the 40 recognized species' nests have been described, and of these only one has incubation patterns described. We provide the first description of the nest architecture, eggs, incubation behavior, and nestlings of the Trilling Tapaculo (Scytalopus parvirostris). The globular nest was mostly built of dark rootlets, and was lined with fern scales, hyphae, and feathers placed within the cavity of a rotting tree 1.5 m off the ground. The nest contained two white eggs. Nest attentiveness averaged 91 ± 0.5% per day, with an average of 12.6 ± 0.3 trips per day. Incubation bouts on the nest averaged 54.6 ± 2.9 mins and foraging trips averaged 8.8 ± 0.7 mins. Combined daily nestling growth rates averaged 18 ± 2% weight, 9 ± 2% tarsus, and 16 ± 3% wing (n  =  4 days).
