“…Although controlling for such spatial dependence allowed improvement of model fit, the model selection statistics showed moderate uncertainty about the most plausible model for occurrence of G. nana. As reported for other Glaucidium species (Campioni et al, 2013), the weak association between resources and G. nana occurrence could indicate a continuum of good habitat conditions across Andean temperate forests. This hypothesis is supported by the fairly uniform level of habitat suitability for G. nana across much of the Villarrica watershed.…”

“…As reported for Glaucidium gnoma and Glaucidium brasilianum, this higher irregularity, as generated by riparian zones and linear human structures (e.g. roads and fences), may provide these owls with different resources and hunting perches with extensive views (Campioni et al, 2013;Piorecky and Prescott, 2006).…”

“…However, they exhibited relatively low occupancy rates in El Imposible NP and on the M-2 route in Montecristo NP. These owls tend to prefer open cover types with a lot of edge habitat, such as the flooded igapo ´forests of Amazonia (Borges et al 2004) and heterogenous forests in central Argentina (Campioni et al 2013). Furthermore, the diet of Ferruginous Pygmy-Owls varies based on forest density (Sarasola and Santilla ´n 2014).…”

Understanding patterns in the occupancy of Neotropical owls can help inform land managers and conservation efforts; however, Neotropical owls are understudied compared to their temperate kin. We conducted the first long-term (10-yr) study of owls in El Salvador to assess occurrence patterns and species richness using occupancy modeling. Our study occurred in El Imposible National Park, Montecristo National Park, and Nancuchiname Forest, and we chose two survey routes per protected area to represent the landscape diversity of the country. Surveys involved passive listening and broadcasting calls of several species at selected points along each route, and we sought to repeat each survey route twice per year. We completed 86 surveys between March and May each year from 2003 through 2013, except in 2006 when no surveys occurred. We detected nine species of owls, including the Stygian Owl (Asio stygius), which was previously undocumented in El Salvador, and we documented 1211 owl records overall. We developed Bayesian, hierarchical, single-species occupancy models for the Mottled Owl (Ciccaba virgata), Ferruginous Pygmy-Owl (Glaucidium brasilianum), and Spectacled Owl (Pulsatrix perspicillata), and a multi-species richness model for all El Salvador owls. We found that the effects of broadcasting calls were species-specific (i.e., broadcasting some species' calls increased detection probabilities while others decreased detection). Nancuchiname Forest was the most species-rich, while the cloud forest of Montecristo National Park had several species that we did not observe elsewhere. In general, we found relatively stable occupancy patterns across the study period, and we recommend some specific areas of further study to inform management decisions.

“…El Caburé Chico utiliza cavidades naturales, nidos abandonados de Hornero (Furnarius rufus) o cajas nido para nidificar (Pereyra 1938;Plotnick 1956;Carrera et al 2008;Cerqueira Lima & Cerqueira Lima Neto 2008;Campioni et al 2013;Liébana y Sarasola 2013;Santos Castro et al 2010;de la Peña 2016;Orozco-Valor & Grande 2016;de la Peña 2020). La época de nidificación de esta especie abarca desde octubre a diciembre (Carrera et al 2008;Cerqueira Lima & de Cerqueira Lima Neto 2008;Campioni et al 2013;de La Peña 2016) y la incubación dura aproximadamente 20 días, siendo la hembra la única que incuba (Santos Castro et al 2010). Según de la Peña (2016), hay una pequeña diferencia de tamaño entre los machos (17 cm) y las hembras (18,5 cm), con pesos que van desde aproximadamente 50 gr para los machos y 90 gr para las hembras.…”

El Caburé Chico (Glaucidium brasilianum) es una pequeña ave rapaz de fácil observación en la Ciudad de Buenos Aires. Sin embargo, no hay registros publicados de nidificación en la Ciudad. En el presente trabajo reportamos observaciones sobre cuatro eventos de nidificación de Caburé Chico en dos parques urbanos. Estos eventos reproductivos fueron observados entre 2015-2020. Estos registros sistemáticos responden a un seguimiento de cinco años en ambos espacios verdes, en los cuales se observaron varios ejemplares de caburés. Reportamos, además, la observación de dos eventos de depredación de una especie exótica por esta rapaz nocturna.
