“…We propose that, in Furnariidae, parental care systems are related to nest complexity and concealment. At one end of the spectrum, cooperative breeding occurs among the builders of elaborate mud or stick nests (many of which also build extra "dummy" nests; e.g., Furnarius, Phacellodomus, Anumbius, Pseudoseisura, Coryphistera, and Acrobatornis; Fraga 1979, Nores and Nores 1994, Rodrigues and Carrara 2004, Areta and Bodrati 2007. These nests are often large and exposed.…”

The Neotropical ovenbirds (Furnariidae) are an adaptive radiation of suboscines renowned for the diversity of their nests. Like most altricial insectivores, they generally exhibit biparental care. One tribe, Philydorini, includes 46 species thought to nest in either underground burrows or tree cavities, nest types traditionally treated as equivalent in phylogenetic studies. Their parental care systems are poorly known, but could help illuminate how uniparental care – typically associated with frugivory – can arise in insectivores. We examined the extent to which nest placement, parental care, and associated reproductive traits map onto two major clades of Philydorini identified by genetic hypotheses. We review published literature and present new information from the Atlantic Forest of Argentina, including the first nest descriptions for Ochre‐breasted Foliage‐gleaners (Anabacerthia lichtensteini) and Sharp‐billed Treehunters (Heliobletus contaminatus). In the Automolus‐Thripadectes‐Clibanornis clade (including Philydor rufum), 134 of 138 reported nests were in underground burrows. In the Syndactyla‐Anabacerthia‐Anabazenops clade (including Heliobletus, Philydor atricapillus, and Philydor erythrocercum), 44 of 48 nests were in tree cavities. Remaining nests were in buildings or species‐level identification was unclear. At least eight species in the first clade, but none in the second clade, excavated their nest sites. Biparental care was confirmed for nine species in the first clade and one species in the second clade. In contrast, nests of A. lichtensteini and H. contaminatus were attended by a single secretive adult. We propose that species in the Automolus‐Thripadectes‐Clibanornis clade are underground burrow excavators, and those in the Syndactyla‐Anabacerthia‐Anabazenops clade are secondary tree‐cavity nesters (nonexcavators). We also note that parental care strategies in Furnariidae vary with nest complexity and conspicuousness – from uniparental care in secretive tree‐cavity nesters to cooperative breeding in highly vocal builders of elaborate nests – suggesting evolutionary links among nest‐building, concealment, and parental care strategies.

“…There are few studies of cooperative breeding species in the neotropical region (Macedo 2008), and only a minor portion of these studies test hypotheses concerning breeding behavior (e.g., Rodrigues and Carrara 2004). Our purpose in this study was to determine the influence of helpers on nestling feeding effort and reproductive outcome of breeders in the neotropical White-banded Tanager (Neothraupis fasciata).…”

In cooperatively breeding birds, breeders can adjust their parental care investment without affecting nestling survival probability and save energy to invest in other activities, such as feeding, mating or territory defense. Furthermore, helpers at the nest can improve nestling nutrition and hence the reproductive performance of the breeding pair. We determined the influence of helpers on nestling feeding effort and reproductive success of breeders in the neotropical White-banded Tanager (Neothraupis fasciata). We monitored nests during the breeding seasons of 2006 and 2007 in central Brazil. Males showed a compensatory reduction of their food delivery rate in the presence of helpers, whereas females exhibited the same parental effort regardless of having helpers. Total food delivery rate was higher for nests with helpers, but there was no effect of helpers on reproductive performance of breeders (clutch size, hatching rate, fledgling productivity and reproductive success). Our results indicate that cooperative breeding in the White-banded Tanager appears to be important for males to reduce their parental care effort and, hence, invest in their survival or future reproductive attempts. Zusammenfassung Bei kooperativ brütenden Vögeln können Brüter ihren Brutpflegeaufwand anpassen, ohne dass dies die Ü berlebenswahrscheinlichkeit der Nestlinge beeinträchtigt, und Energie sparen, die dann in andere Aktivitäten, wie Nahrungsaufnahme, Paarung oder Revierverteidigung, investiert werden kann. Außerdem können Helfer am Nest die Ernährung der Nestlinge und somit die Fortpflanzungsleistung des Brutpaares verbessern. Wir haben ermittelt, wie sich Helfer auf den NestlingsFütterungsaufwand und den Fortpflanzungserfolg von brü-tenden neotropischen Flügelbindentangaren (Neothraupis fasciata) auswirken. Wir haben Nester während der Brutsaisons 2006 und 2007 in Zentralbrasilien überwacht. Männchen zeigten eine kompensatorische Reduktion ihrer Fütterungsrate in Anwesenheit von Helfern, während Weibchen denselben Elternaufwand zeigten, unabhängig davon, ob sie Helfer hatten oder nicht. Die Gesamtfütterungsrate war für Nester mit Helfern höher, doch Helfer hatten keinen Einfluss auf die Fortpflanzungsleistung von Brütern (Gelegegröße, Schlupfrate, Flügglingsproduktion und Fortpflanzungserfolg). Unsere Ergebnisse deuten darauf hin, dass kooperatives Brüten bei Flügelbindentangaren für Männchen wichtig zu sein scheint, um ihren Brutpflegeaufwand zu reduzieren und folglich in ihr Ü berleben oder weitere Fortpflanzungsversuche zu investieren.

“…Extremamente sedentário, H. rectirostris defende um território ao longo de todo ano (L.F. observação pessoal), a semelhança de outros furnarídeos já estudados como P. rufifrons (RODRIGUES & CARRARA 2004) e Furnarius rufus (Gmelin, 1788) (FRAGA 1980). Apesar da participação da fêmea em algumas ocasiões, geralmente quando acompanhada de seu parceiro, a defesa do território é tarefa realizada na maioria das vezes pelos machos.…”

O fura-barreira Hylocryptus rectirostris é uma ave endêmica das matas ciliares da região do Cerrado, considerada rara a incomum e prioritária para pesquisa. A ausência de dimorfismo sexual aparente é o padrão disseminado entre os Furnariidae, no entanto, para algumas espécies da família foram encontradas diferenças morfométricas entre os sexos, sugerindo pressões evolutivas e exigências ecológicas distintas entre machos e fêmeas. O objetivo deste trabalho foi verificar a existência de dimorfismo sexual de tamanho de uma população de H. rectirostris do Parque Nacional da Serra do Cipó, Minas Gerais, sugerindo uma hipótese capaz de explicar a diferença observada entre os sexos. Para tanto foram tomadas sete medidas corporais de 21 indivíduos (13 machos e oito fêmeas) capturados entre abril de 2004 a novembro de 2005 e sexados por meio de técnicas moleculares. Os machos apresentaram asa e cauda significativamente maiores do que as fêmeas (asa: U = 5,5, p = 0,0008; cauda: U = 8,0, p = 0,0014). Acredita-se que as diferenças estejam relacionadas à defesa territorial, tarefa executada quase que exclusivamente por machos, que mantêm territórios estabelecidos ao longo de todo ano mesmo na ausência de fêmeas. Rêmiges e retrizes mais longas incrementam a capacidade de vôo e devem favorecer os indivíduos com asas e caudas maiores durante a aquisição e defesa de territórios, processos essenciais à conquista de fêmeas e conseqüente sucesso reprodutivo.
