Review of the breeding status of birds in Rio Grande do Sul, Brazil
Provedor de dados: 76
Autores: Maurício,Giovanni N.; Bencke,Glayson Ariel; Repenning,Márcio; Machado,Diogenes Borges; Dias,Rafael A.; Bugoni,Leandro.
Information on the breeding biology of birds is essential for improving avian life-history theory and implementing sound management and conservation actions for these organisms. Comprehensive reviews of this kind of information are lacking for most Neotropical regions, including Rio Grande do Sul, the southernmost Brazilian state. Aiming to update the knowledge on the reproductive status of birds in Rio Grande do Sul, we reviewed breeding records of all potential breeding species recorded in the state using a set of predefined, restrictive criteria for accepting breeding evidences as effective. Data satisfying our criteria were available for 165 species in the literature. We also collected novel breeding information obtained in the state for an additional...

Pollen of Syzygium (Myrtaceae) from SE Asia, especially Thailand
Provedor de dados: 16
Autores: Parnell, J.
Pollen of 57 species of Syzygium from SE Asia were surveyed by SEM. The grains are all ± triangular in polar view, uniformly small (mean diameter 10.4 μm) with few surface sculpturing features. All species examined exhibit a distinct apocolpium and, usually, apocolpial field. The presence of an apocolpial field cannot be linked to any known taxonomic grouping within the genus. It does not appear possible to distinguish the species of Syzygium on the basis of features of the pollen visible under SEM, though section Jambosa tends to have larger pollen with a proportionally larger apocolpium than species not in that section. Estimates for the number of pollen grains per stamen in species with larger pollen grains (± section Jambosa) are 5× as great as for...

Multiple nesting attempts and long breeding seasons of Mimus gilvus (Aves: Mimidae) in southeastern Brazil
Provedor de dados: 103
Autores: Morais,Rodrigo; Araújo,Luiz Carlos de; Silva,Gleidson Ramos da; Duca,Charles.
ABSTRACT This study describes aspects of the life history of the Tropical Mockingbird Mimus gilvus (Vieillot, 1808), including the breeding period, clutch size, nestlings and a list of plants used for nesting. Nests were monitored in an area of Restinga (sand-coastal plain) habitat in a protected area in southeastern Brazil. The data from 181 nests during five breeding seasons (2010-2014) showed that the Tropical Mockingbird has a long breeding season (26.1 ± 2.6 weeks) with up to two peaks of active nests from August to March. The breeding pairs made up to four nesting attempts in the same breeding season. The mean (± SD) clutch size was 2.4 ± 0.6 eggs (n = 169). The mean (± SD) incubation period was 14 ± 0.6 days, and the nestling remained in the nest...

Reproductive behavior of the Red-crested Finch Coryphospingus cucullatus (Aves: Thraupidae) in southeastern Brazil
Provedor de dados: 103
Autores: Zima,Paulo V.Q.; Francisco,Mercival R.
ABSTRACT Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests. This information may be valuable to elucidate the phylogenetic relationships of this bird, and to design plans to manage it. Nesting activities occurred from October to February. Clutches consisted of two to three eggs (2.06 ± 0.25), which were laid on consecutive days. Incubation usually started the morning the females laid their last egg and lasted 11.27 ± 0.47 days. Hatching was synchronous, or happened at a one-day interval. The nestling stage lasted 12 ± 0.89 days. Only females incubated the eggs and they fed the young more often than the males did. Overall...

Reproductive aspects of the Purple-throated Euphonia, Euphonia chlorotica (Aves: Fringillidae) in southeastern Brazil, and first record of the species nesting inside a vespiary
Provedor de dados: 103
Autores: Perrella,Daniel F.; Davanço,Paulo V.; Oliveira,Leonardo S.; Sousa,Livia M.S.; Francisco,Mercival R.
ABSTRACT Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and 2012. Nests were globular with a lateral entrance, and measured 97.9 ± 14.4 mm in outside height, 110.6 ± 11.6 mm in outside diameter, and were 4.88 ± 2.09 m above ground. They were often supported from bellow and were composed mainly of tiny dry leafs and leaflets, fine petioles, and plumed seeds, all compacted with spider web silk. Eggs were laid on consecutive days or with one day interval, and clutch size varied from 1-3 eggs (2.1 ± 0.6, n = 9 nests). Only females incubated the eggs, but both...

Additional information on reproductive behavior of the Red-breasted Toucan, Ramphastos dicolorus (Aves: Piciformes: Ramphastidae)
Provedor de dados: 49
Autores: Perrella,Daniel Fernandes; Guida,Fernanda Junqueira Vaz.
Abstract: Ramphastidae is Family of secondary cavity-nesting birds that is endemic to the Neotropical region. Here we provide a comprehensive literature review of nest measurements, and new information on characteristics of the nest cavity, parental nest attendance, incubation and nestling period of the Red-breasted Toucan, Ramphastos dicolorus. We also add information on the origin of the seeds found inside toucan nests and propose a potential function for them. Eight nests were studied in three cavities during six breeding seasons at Parque Estadual das Fontes do Ipiranga, São Paulo, and at a private allotment in Ibiúna, southeastern Brazil. The reproductive activities of the birds were observed from September to February. In one cavity, we found the...
