“…Given the important role they play in local environments, the literature surrounding ecosystem engineers is historically focused on how their actions affect other species (Jones et al, 1994;Robles & Martin, 2013;Tarbill, Manley, & White, 2015;Wiebe, 2017), but little research has been done concerning external factors that influence the engineers themselves (see Mikusinski, 2006;Jusino, Lindner, Banik, & Walters, 2015). Importantly, little has been done to investigate how ecosystem engineers choose breeding and young rearing grounds (Nilsson, Johnsson, & Tjernberg, 1991;Garmendia, Cárcamo, & Schwendtner, 2006). Understanding these driving factors is essential to understanding the ecology of not only the ecosystem engineers themselves, but the organisms that rely on them for their own breeding and nesting grounds as well.…”

Understanding how ecosystem engineers influence other organisms has long been a goal of ecologists. Woodpeckers select nesting sites with high food availability and will excavate and then abandon multiple cavities through their lifetime. These cavities are crucial to secondary cavity nesting birds (SCB) that are otherwise limited by the availability of naturally occurring cavities. Our study examined the role food resources have on the nest site location and home range size of woodpeckers, and the respective influence woodpeckers and the construction of cavities have on the nesting success of SCB. Using five years of avian point count data to locate golden-fronted woodpeckers (GFWO: Melanerpes aurifrons), we correlated insect availability with GFWO home range size and determined differences in insect availability between GFWO occupied and unoccupied sites, while recording nesting success (success: ≥ 1 fledgling) for the GFWO and common SCB in south Texas: Black-crested Titmouse (Baeolophus atricristatus), Ash-throated Flycatcher (Myiarchus cinerascens), Brown-crested Flycatcher (Myiarchus tyrannulus), and Bewick's Wren (Thryomanes bewickii). We used model averaging to fit species-specific logistic regression models to predict nest success based on cavity metrics across all species. Sites occupied by GFWO had a higher biomass of insects in orders Coleoptera, Hymenoptera, and Orthoptera than unoccupied sites, and there was a negative correlation between the availability of these insect orders and home-range size. GFWO had increased nest success in trees with increased vegetation cover and lower levels of decay, while SCB had higher levels of nesting success in abandoned GFWO cavities opposed to naturally occurring ones, and in trees with low decay. Our results suggest that SCB may be drawn to nest in abandoned woodpecker cavities where they have higher rates of nest success compared to natural cavities. Additionally, the prevalence for GFWO to excavate cavities in trees with lower levels of decay contradicts previous literature and may indicate a novel temperature trade-off, with live trees requiring more energy to excavate, but providing more protection from high breeding season temperatures in arid and semi-arid areas.

“…Los pícidos constituyen un grupo de aves forestales de gran interés desde un punto de vista del ecosistema, ya que se consideran "arquitectos del paisaje" al contribuir a la creación de recursos que posteriormente son utilizados por un buen número de especies (Sekercioglu, 2006). Además, algunos pícidos se encuentran amenazados, por lo que tienen también interés para la conservación y gestión (Garmendia et al, 2006, Roberge et al, 2008, Cockle et al, 2011.…”

La población de pico dorsiblanco Dendrocopos leucotos lilfordi Sharpe & Dresser, 1871 en España se estima en torno a las 100 parejas, el 98% de la cual se localiza en Navarra. Gracias al seguimiento de la nidificación de la especie en Navarra durante los últimos años, se han podido recolectar gran cantidad de datos sobre el sustrato de nidificación y parámetros reproductivos. El objetivo de este artículo es (1) actualizar y contribuir al conocimiento de la nidotópica de la especie en Navarra, (2) describir su reproducción (tamaño de puesta y razón de sexos de la nidada) y (3) proponer, en relación a los resultados que se exponen, medidas de gestión útiles para su conservación. En cuanto al sustrato de nidificación (n = 56 pies), todos los nidos se localizaron en haya, la mayoría de ellos en pies puntisecos o totalmente verdes (46%), seguido de árboles secos (40%) y, finalmente y más rara vez, hayas mitad secas-mitad sanas (14%). En promedio, la altura de los pies con nido fue 19,1 ± 8,1 m y la altura de los nidos fue de 11,1 ± 4,2 m. En promedio, la altitud de los nidos se situó a 943,8 ± 99,0 m. s. n. m. y la orientación de los nidos fue heterogénea, siendo en este caso el promedio de 180 ± 92º. La productividad se estimó en 1,4 ± 0,7 pollos/nido (rango = 0-3; n = 40). La productividad no varió entre las dos zonas (Belate y 31 Nidotópica y productividad del pico dorsiblanco en Navarra

“…In Central Europe the species is considered by some authors as inhabitants of large managed forests and an indicator of old-growth conditions (Hölzinger and Kroymann 1981, Scherzinger 1981, 1989. In Spain too, the species has shown a preference for mature stands with older trees (Garmendia et al 2006 ). However, studies carried out in Northern Europe have criticised the use of the Black Woodpecker as an indicator species of old-growth conditions, since feeding activity was also found in young plantations dominated by Norway spruce Picea abies and with high canopy closure (Rolstad et al 1998 ).…”

The Black Woodpecker Dryocopus martius is the largest woodpecker of the Palearctic Region and it has been recognised as a keystone species whose presence provides critical resources to secondary cavity-users in European forest ecosystems. Here we investigate cavity tree and foraging-habitat selection of Black Woodpecker in three natural parks located in the central and eastern Italian Alps and included in the Natura 2000 network. A total of 94 cavity trees were identified, showing a minimum diameter of 35 cm and a mean diameter of 51 cm. We counted 30 active nests, but only 40% were newly excavated. Silver fir Abies alba and larch Larix decidua were preferred as cavity trees, with silver fir also associated with habitat surrounding the cavity trees. Norway spruce Picea abies and Silver fir were found to be positively associated with the surroundings of feeding sites. Logistic regression models identified the average diameter at breast height and the average tree crown height as significant predictors, positively associated with both cavity trees (AUC: 0.988) and cavity tree plots (AUC: 0.866). Also, the total volume of dead logs and the percentage of understorey cover turned out to be significant predictors of feeding sites, showing a positive and a negative association, respectively (AUC: 0.708). Cross validation of logistic regression models indicated that only cavity tree models can be considered useful tools in conservation practice. Overall, our results indicated that the Black Woodpecker behaves like an opportunist when choosing feeding sites. On the other hand, our results also indicate that the Black Woodpecker clearly behaves as a demanding species when it selects cavity trees, showing a hierarchical pattern in habitat selection and a marked preference for large trees with high crown height. We discuss the implications of our results for the conservation of the Black Woodpecker in Natura 2000 alpine sites.
