“…It has a relatively large home range ( Table 2) and is sensitive to the disappearance of its habitat given its dependence on dead wood for food and shelter (Lemaître and Villard, 2005;Virkkala, 2006). It has also been observed that the presence of forest birds, such as the pileated woodpecker, is affected by the amount of forest habitat that is available and the structure of the landscape (Bull et al, 2007). The black bear is a generalist species that uses a large variety of habitats during its annual life cycle (Samson, 1996;Naughton, 2012).…”

“…Like other large woodpecker species, Magellanic Woodpeckers have relatively long parental care duration (two to three years), large territories (0.2 to 1.3 km²) and low densities (0.1 to 1.8 individuals/km²), which make them highly sensitive to forest loss and degradation caused by logging, wildfires, and natural disasters (Vergara and Schlatter 2004, Chazarreta et al 2011, Soto et al 2012, Ojeda and Chazarreta 2014, Vergara et al 2014; see also Lammertink et al 2009). Specifically, the loss of large, dying, or dead trees reduces availability of foraging, roosting, and nesting sites and, thus, induces population declines across multiple species of woodpeckers (Lammertink 2004, Mikusinski 2006, Bull et al 2007, Pasinelli 2007, Lammertink et al 2009, Kumar et al 2014, Nappi et al 2015. Remote sensing-based methods have proven to be effective in identifying trees with advanced decay stages, thus providing information on the quality of foraging habitat of Magellanic woodpeckers , Vergara et al 2017.…”

ABSTRACT. A major challenge for protected areas is providing wildlife with enough suitable habitat to cope with stochastic environment and increased pressure from the surrounding landscapes. In this study, we addressed changes in local populations of Magellanic Woodpeckers (Campephilus magellanicus) occupying three national parks of central-southern Chile. We compared the breeding and postbreeding abundance of woodpeckers during the 1990s with the present (2016) abundance (n = 4 years), and assessed the extent to which abundance was explained by forest type and quality of foraging habitat (as quantified through the plant senescence reflectance index; PSRI). Results show a distinctive temporal variation in woodpecker abundance at each park, with local populations of Magellanic Woodpeckers declining by 42.2% in Conguillío National Park, but increasing by 34.3% in Nahuelbuta National Park. Woodpeckers responded to forest conditions within each park such that their abundance increased with high quality of foraging habitat, i.e., large PSRI values, and the presence of old-growth Monkey puzzle (Araucaria araucana) -Nothofagus pumilio mixed forest. Anecdotal evidence suggests that populations of woodpeckers in Conguillío National Park might have responded negatively to large-scale disturbances from recent forest fires affecting part of the forest area within park. Because stochastic events seemed to strongly mediate population changes, our findings suggest that regional conservation of Magellanic Woodpeckers requires expanding the current conservation area network in central-southern Chile. Le Pic de Magellan dans trois parcs nationaux du centre-sud du Chili : effets de l'habitat et variation des populations durant les deux dernières décenniesRÉSUMÉ. Les aires protégées font face au défi important de fournir suffisamment d'habitat propice à la faune pour compenser le côté imprévisible de l'environnement et les pressions grandissantes provenant des paysages voisins. Dans le cadre de la présente étude, nous avons évalué les changements advenus dans les populations locales du Pic de Magellan (Campephilus magellanicus) qui fréquentent trois parcs nationaux du centre-sud du Chili. Nous avons comparé les effectifs de ce pic en nidification et en post-nidification dans les années 1990 avec ceux de 2016 (n = 4 années), et évalué dans quelle mesure les effectifs étaient reliés au type forestier et à la qualité des aires d'alimentation (quantifiée par l'indice de réflectance de la sénescence végétale; en anglais PSRI). Nos résultats montrent une variation temporelle des effectifs de pics distincte dans chaque parc : la population locale de Pics de Magellan a diminué de 42,2 % dans le parc national Conguillío, mais a augmenté de 34,3 % dans le parc national Nahuelbuta. Les pics se sont adaptés aux conditions forestières dans chaque parc, de sorte que leur abondance a augmenté là où les aires d'alimentation étaient de grande qualité, c.-à-d. avec des valeurs de PSRI élevées, et en fonction de la présence de forêt mélangée âgée de ...

“…Woodpeckers are highly sensitive to anthropogenic forest disturbances that cause the loss of their foraging and breeding structures at different spatial scales (e.g., snags or large decaying trees; Lammertink 2004, Bull et al 2007. Humans can indirectly contribute to the degradation of bird habitats by introducing mammal species that feed on trees and alter forest ecosystems, including feral goats, rabbits, feral cattle, hogs, and beavers (Hahn et al 2011).…”

SUMMARYThe effect of the disturbances caused by the American beaver (Castor canadensis), introduced to the Cape Horn Biosphere Reserve, on species of birds that are forest habitat specialists is poorly understood. Using telemetry data, we determined which attributes of abandoned beaver meadows have a strong impact on habitat selection by the Magellanic woodpecker (Campephilus magellanicus). We detected a positive relationship between the woodpecker habitat use and the fraction of old-growth forest located near these meadows. These results suggest that favorable habitat conditions are generated around small meadows with old-growth forest, because they might increase availability of wood-boring larvae.Key words: American beaver, Campephilus, habitat selection. RESUMENEl efecto que tienen las perturbaciones causadas por el castor norteamericano (Castor canadensis) -introducido en la Reserva de Biosfera Cabo de Hornos-sobre especies de aves especialistas de hábitat forestales es poco conocido. Utilizando datos de telemetría determinamos qué atributos de las castoreras abandonadas tienen una mayor influencia en la selección del hábitat por los carpinteros negros (Campephilus magellanicus). Existe una asociación negativa entre el uso del hábitat por carpinteros y el tamaño de las castoreras, mientras que los carpinteros muestran preferencias por el bosque antiguo ubicado cerca de estas castoreras. Estos resultados sugieren condiciones de hábitat favorables cerca de las castoreras pequeñas y rodeadas de bosque antiguo, probablemente debido a un aumento en la disponibilidad de larvas taladradoras de madera.Palabras clave: Castor norteamericano, Campephilus, selección de hábitat.
