Resumen:
We provide the first description of the nest of the Scalloped Woodcreeper (Lepidocolaptes
falcinellus), its clutch size, nestlings, and nesting behavior from prospecting to fledging, based on 102 h
of observation at a nest in the subtropical Atlantic forest at Parque Provincial Cruce Caballero, province
of Misiones, Argentina. The nest was in a long vertical crack, 2.5 m high in the trunk of a cedro (Cedrela
fissilis). The two adults filled the bottom of the cavity with bark flakes to a height of 11 cm. They took turns
incubating the three eggs with 100% attentiveness for 1516 days, and fed the two nestlings a diet of
arthropods, especially caterpillars. After the male died, the female raised the nestlings alone and they
fledged two days apart, 18 and 19 days after hatching. The Scalloped Woodcreepers were observed on
four occasions defending their nest against potential predators and cavity competitors (White-throated
Woodcreeper, Xiphocolaptes albicollis; Yellow-fronted Woodpecker, Melanerpes flavifrons; Olivaceous
Woodcreeper, Sittasomus griseicapillus). Our observations of nest construction, incubation period, nestling
development, nestling period, and parental behavior for Scalloped Woodcreepers were similar to
published observations for Streak-headed Woodcreepers (Lepidocolaptes souleyetti) and Spot-crowned
Woodcreepers (L. affinis) of tropical Central America; however, Scalloped Woodcreepers had longer
bouts on the nest and higher nest-attentiveness during incubation, and in these characteristics were similar
to Planalto Woodcreepers (Dendrocolaptes platyrostris) that breed at the same site in northeastern
Argentina.
