I studied two nests of Grey-breasted Flycatcher Lathrotriccus griseipectus in seasonally deciduous dry forest in south-west Ecuador. Nests were open cups constructed in natural depressions, one in the buttress of a large tree and one in a clump of bromeliads. Construction of one nest was completed in five days. Clutch size was two at one nest, and the eggs were pale beige with sparse, red-brown blotching. Eggs at both nests were laid 48 hours apart, and at one nest both eggs hatched 16 days after clutch completion. One nest was depredated immediately after the second egg was laid, but both nestlings fledged after 14 days at the other. Only one adult incubated, but both provisioned nestlings. The species' breeding biology is similar in all respects to that of the congeneric Euler's Flycatcher L. euleri, as well as to members of the closely related genus Empidonax of temperate and subtropical America. © 2014 British Ornithologists' Club.

Our observations on the reproductive habits of the Slaty-backed Nightingale-Thrush (Catharus fuscater) were made at a single nest between 2-12 November 2009 at an elevation of 2,050 m, in the vicinity of the Yanyacu Biological Station and Center of Creative Studies (00° 36′ S, 77° 53′ W), 5 km west of Cosanga (Napo Province, northeastern Ecuador). During the first 3 days following hatching, the only adult which provisioned nestlings was a color-banded female. Beginning with day 4, however, we observed five other individuals bringing food to the nest, including three color-banded males, one unmarked male, and one unmarked individual presumed to be female. The last two birds and one of the banded males were sexed using morphological differences, the remaining banded individuals were sexed molecularly. Most (72%) of provisioning visits to 4-9 day old nestlings were made by the color-banded female which also incubated the eggs. Our observations suggest the existence of a potentially complex cooperative breeding system in Slaty-backed Nightingale-Thrush. © 2015 The Wilson Ornithological Society. Source

We document male and female roles in nestling care of Spotted Barbtails (Premnoplex brunnescens) including feeding rates and temporal patterns of provisioning by each sex. Using 128.5 hrs of video from color marked and molecularly sexed individuals at two nests, we confirm that both sexes of Spotted Barbtail provision nestlings. Spotted Barbtail females in our study invested more heavily in nestling care than males, making 73% of feeding visits. Females also visited the nests nearly twice as often as males, averaging 1.24 visits/nestling/hr compared to 0.69 visits/nestling/hr for males. While Spotted Barbtails exhibit many of the features assumed to favor social and genetic monogamy, intriguing aspects of nest building and incubation leave open the possibility that this species is unusual among the Furnariidae and utilizes extra-pair matings as a part of the reproductive strategy. © 2015 by the Wilson Ornithological Society.

Zootaxa | Year: 2011

The taxonomy of the Andean butterfly genus Daedalma (Nymphalidae, Satyrinae) is discussed. Generic synapomorphies based on adult morphology are proposed, and the relationships with allied genera of the subtribe Pronophilina are evaluated. The status of Junea as the sister-genus of Daedalma is reconsidered, particularly in light of new data on the larval stages. The genus Daedalma is divided into two presumed monophyletic groups distinguished by a series of morphological and ecological characters. Three species, D. eliza n. sp., D. dognini n. sp. and D. rubroreducta n. sp., and seventeen new subspecies are described, one new status is proposed, and three lectotypes are designated. Female genitalia of Daedalma are described for the first time and their taxonomical value is assessed. The early stages of D. rubroreducta and D. dinias are described, the first larval descriptions for any species of Daedalma. Distribution and diversity patterns of Daedalma are discussed. Distribution maps, illustrations of male and female genitalia, and figures of adult butterflies of both sexes are provided for all taxa where possible, with comments on bionomics and adult behaviour for all taxa in the genus. © 2011 Magnolia Press.

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. © 2014 The Neotropical Ornithological Society. Source
