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...
One of the five most important global biodiversity hotspots, Neotropical Atlantic forest supports a diverse community birds that nest in tree cavities. Cavity-nesting may be particularly sensitive to forestry and agricultural practices remove potential trees; however, there have been few efforts determine what constitutes forests. We aimed characteristics trees cavities used nesting by excavators (species excavate their own cavity) secondary cavity-nesters rely on existing cavities),...
Abstract Global-scope scientific journals have played an important role in upholding a colonial legacy of north-south inequities ornithology, and they now key to play increasing equity publishing. We explore common barriers faced by ornithologists the Neotropics (Latin America Caribbean) suggest priority actions that Ornithological Applications, Ornithology, other global-scope ornithological can take increase publication research uptake. Among most problems, we identified (1) restrictive...
ABSTRACT Cavity‐nesting birds and mammals exhibit species‐specific nest‐site selection for tree characteristics cavity dimensions. Although trees their cavities change as they age, with becoming softer larger, it is not known how value nesting resources varies age. In the context of wildlife forest management, we investigated relative generating a supply fresh cavities, which are thought to be high quality, versus protecting age expand in interior volume. For 21 years (1995–2016), monitored...
Logging often reduces taxonomic diversity in forest communities, but little is known about how this biodiversity loss affects the resilience of ecosystem functions. We examined partial logging and clearcutting temperate forests influenced functional birds that nest tree cavities. used point-counts a before-after-control-impact design to examine effects on value, range, density traits bird communities Canada (21 species) Chile (16 species). Clearcutting, not logging, reduced both systems. The...
Woodpeckers and other excavators create most of the holes used by secondary cavity nesters (SCNs) in North American temperate mixedwood forests, but degree to which release SCNs from nest-site limitation is debated. Our goal was quantify how maintain diversity abundance a forest through creation tree cavities. We examined short- long-term (legacy) effects (principally woodpeckers, also red-breasted nuthatches black-capped chickadees) on biodiversity using longitudinal monitoring data (1,732...

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...
Network analysis offers insight into the structure and function of ecological communities, but little is known about how empirical networks change over time during perturbations. "Nest webs" are commensal that link secondary cavity-nesting vertebrates (e.g., bluebirds, ducks, squirrels, which depend on tree cavities for nesting) with excavators woodpeckers) produce cavities. In central British Columbia, Canada, Northern Flicker (Colaptes auratus) considered a keystone excavator, providing...
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 Passive restoration of secondary forests can partially offset loss biodiversity following tropical deforestation. Tree cavities, an essential resource for cavity-nesting birds, are usually associated with old forest. We investigated the time tree cavities suitable birds in forest at Biological Dynamics Forest Fragments Project (BDFFP) central Amazonian Brazil. hypothesized that cavity abundance would increase age, but more rapidly areas exposed to cutting only, compared where was...
Abstract Many ornithologists seek tools to work more equitably with people from historically marginalized and exploited groups. We developed a process promote collective construction of ornithological knowledge in the Special Feature series "Ecology conservation cavity nesters Neotropics'' for journals Ornithology Ornithological Applications. Colonialism produces systems that consecrate Eurocentric ideas dominant nations (including Canada, USA, countries western Europe) reinforce hierarchies...
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...
Many animals require tree cavities for breeding and these sites may be reused by a diversity of secondary cavity nesters over timespan decades. It is unknown whether the reuse holes changes their desirability as nest sites. We hypothesized that some species, "cavity destroyers", degraded quality filling them with coarse material or waste whereas other cleaners", might prolong use hole removing debris enlarging hole. Using data gathered during 22 years from field study in central British...
