Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state...
ABSTRACT Most bamboos are semelparous. Their synchronous masting events occur on a cycle of 3–120 yr and represent an extremely pulsed resource for granivorous birds. Although many bird species feed occasionally bamboo seeds, there constraints to specializing such fluctuating few known specialize seeds. Three these endemic the Atlantic forest South America: purple‐winged ground‐dove Claravis godefrida , buff‐fronted seedeater Sporophila frontalis Temminck's falcirostris . All three...
Predation is the major cause of avian nest failure, and an important source natural selection on life history traits reproductive behavior. However, little known about identity predators in much world, including Neotropics. To identify some exerting pressure birds subtropical Atlantic forest, we present observations animals depredating bird nests Argentina Paraguay. We recorded depredations (destruction or removal eggs nestlings) at 33 25 species birds, confirming as ten (Squirrel Cuckoo...
Abstract To understand the evolution, life-history tradeoffs, and population ecology of cavity nesters, it is critical to identify avian lineages circumstances in which birds excavate tree cavities. Woodcreepers (Furnariidae: Dendrocolaptinae; 56 species) are considered non-excavators dependent on existing We overturn this assumption by providing definitive evidence that Lesser Woodcreeper (Xiphorhynchus fuscus, 23 g) a facultative tree-cavity excavator. From 2007 2022 Atlantic forest...
ABSTRACT Vinaceous Amazons (Amazona vinacea) are endemic to the Atlantic forest of southeastern Brazil, eastern Paraguay, and province Misiones in Argentina. We searched for throughout western part its range Argentina Paraguay during 1639 days fieldwork from 1997 2006. These parrots have disappeared most areas where they were historically recorded these countries, now limited a few sites northeastern central (Argentina). estimate minimum remaining populations at 220 individuals 203 Important...
Long-distance migratory aerial insectivores are among the most threatened groups of birds breeding in North America, yet little is published about two-thirds their annual cycle that unfolds South America. To study non-breeding ecology and migration Common Nighthawk (<em>Chordeiles minor</em>), we observed, captured, GPS-tagged individuals at Reserva Natural Rincón de Santa María, an Important Bird Area on Paraná River Corrientes, Argentina, from 2017 to 2022 (237 captures, 95 individuals,...
Abstract We provide new information on all birds known from San Rafael National Park, Paraguay. Ornithological records the period 1997 to 2006 have been reviewed, adding 112 species reserve's avifauna. data presence of 405 in seven basic habitats types, and their relative abundance. Biogeographically, has a mixed avifauna, consisting 70 Atlantic Forest endemic species, two Mesopotamian Grassland endemics, many with wider distribution South America. At least 12 are threatened 16...
Semelparous woody bamboos flower fairly synchronously and in clocklike fashion after many years, providing abundant nutritious seeds. However, this resource is ephemeral, localized, unpredictable from the perspective of birds that feed on those Birds specializing bamboo seeds track food source are nomadic. We recorded Temminck's Seedeater (Sporophila falcirostris) at 29 localities Buffy-fronted (S. frontalis) 23 Argentina, Paraguay, southeastern Brazil. In these species, nomadism...
We provide the first description of nest, eggs, and nestlings Planalto Woodcreeper (Dendrocolaptes platyrostris), a secondary cavity-nester, based on three nests in natural cavities 14 nest boxes. Nests were found from October to January 1997, 2006, 2007 humid Chaco Atlantic Forest Argentina. Woodcreepers used boxes 40–60 cm deep with entrance diameters 5–12 cm. They selected deepest available. Three or four white eggs laid bed bark flakes incubated for 14–16 days. Newly hatched had pink...

Despite recent advances, the knowledge scarcity on Furnariidae forest species reproduction continues to bias ideas and limit understanding of avian life history. We studied reproductive biology Lesser Woodcreeper (Xiphorhynchus fuscus; Dendrocolaptinae), which nests in tree cavities, contribute observations toward about evolution ecology. In Atlantic Forest Argentina (2007–2022), we inspected 26 (total: 333 visits), color-banded nine adults, conducted 180 h focal at 11 nests, analyzed...
El Burrito Pico Rojo (Mustelirallus erythrops) es una especie con mínima información sobre su distribución e historia natural, y uno de los rálidos menos conocido las Américas. En Argentina, durante la mayor parte del siglo XX, se lo indicó solo en el rincón noroeste país. Factores como sus hábitos crípticos, desconocimiento general voces, corto período actividad vocal dificultan detección estudio. Compilamos presencia Argentina a partir trabajo campo, búsquedas bibliográficas revisión...
The Neotropical ovenbirds (Furnariidae) are an adaptive radiation of suboscines renowned for the diversity 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, types traditionally treated as equivalent phylogenetic studies. Their parental care systems poorly known, but could help illuminate how uniparental – typically associated with frugivory can...
En Argentina, el Carpinterito Ocráceo (Picumnus nebulosus) es considerado críticamente amenazado. Entre las causas claves que influirían en su estado de conservación se encuentran: reducido rango distribución y la potencial construcción represa Garabí-Panambí anegaría mayor parte del hábitat especie. este artículo, presentamos un registro documentado selva ribereña río Uruguay, con abundancia lianas trepadoras, Yapeyú, Corrientes, 20 agosto 2022.

To understand the evolution of reproductive strategies and social behavior in woodpeckers (Picidae), it is useful to compare breeding biology between two largest subfamilies: Picinae (true woodpeckers) Picumninae (piculets). The piculets include four species Old World (Sasia, Verreauxia, Picumnus spp.) a recent radiation 25 spp. Neotropics; however, information about their limited. We studied nests one roost Ochre-collared Piculet (Picumnus temminckii) Atlantic Forest Misiones eight...
Los loros son a menudo considerados plagas agrícolas; sin embargo, difieren de otras especies plaga por ser estrategas K (larga vida y baja tasa reproductiva). Estas no se recuperarían fácilmente del control letal que implementa para evitar daños los cultivos. El Maracaná Lomo Rojo (Primolius maracana) está virtualmente extinto en Argentina aunque la retracción ambiental su hábitat ha sido señalada como principal causa desaparición, logra explicarla satisfactoriamente. Basados 779 días...
We report on the breeding biology of White-throated Woodcreeper (Xiphocolaptes albicollis), a species endemic to Atlantic forest South America, based 16 nesting attempts in 11 cavities (9 natural tree and 2 nest boxes) Misiones, northeastern Argentina. Natural were 3.3–8.3 cm diameter 46–103 depth, generated by decay processes (not woodpeckers) at heights 3–17 m live trees 29–106 breast height. Woodcreepers laid 2–4 eggs alternate days, bed comprised bark flakes, leaf fragments seed pods....

La Viudita Enmascarada (Fluvicola nengeta) se distribuía históricamente en el noreste de Brasil. En las últimas décadas ha ampliado su distribución hacia sur y oeste, alcanzando estados del sudeste Brasil donde previamente no hallaba. Presentamos primer registro para Paraguay segundo Argentina, los cuales amplían aún más dicha distribución. Estas observaciones apoyan la opinión quienes sugieren que expansión está favorecida por alteraciones humanas ambiente. Adicionalmente, sugerimos uso...
