Abstract
We document the nestling care of the Spotted Barbtail (Premnoplex brunnescens) including provisioning rates and items brought to the nest. Based on 230 hours of video spanning from hatch to fledging at a single nest, we confirm that both sexes of the Spotted Barbtail primarily provision nestlings with arthropods (89.7%) but also document the first feeding of frogs in the genus Premnoplex. Concurrent with a sudden drop in daily brooding time, provisioning rates increased significantly when nestlings reached 10 days of age (from 2.29 ± 0.38 to 5.25 ± 0.76 feeds/nestling/h). We also document unassisted fecal sac ejection by nestlings beginning by 10 days of age. Our observed length of the nestling period was 22 days
