Trends in Threat Status and Priorities in Conservation of the Woodpeckers of the World
(Museum & Inst Zoology, 2014-12)
Taking the first IUCN Red List from 1988 as a starting point, I review trends in the threat status of the woodpecker species of the world, the geographical distribution of (near-) threatened woodpecker species, threat ...
Foraging Behaviour in Magellanic Woodpeckers Is Consistent with a Multi-Scale Assessment of Tree Quality
(Public Library Science, 2016)
Theoretical models predict that animals should make foraging decisions after assessing the quality of available habitat, but most models fail to consider the spatio-temporal scales at which animals perceive habitat ...
Comparison of nesting ecology of three co-existing Atlantic Forest woodpeckers reveals narrow specialization in the Helmeted Woodpecker Celeus galeatus
(Polish Academy of Sciences. Museum and Institute of Zoology, 2020-06)
The Atlantic Forest in southeastern South America is a biodiversity hotspot with high species richness and high forest loss. Three large to medium-sized woodpecker species (Robust Woodpecker Campephilus robustus, Lineated ...
Woodpeckers, decay, and the future of cavity-nesting vertebrate communities worldwide
(Ecological Society of America, 2011-09)
In forests worldwide, tree-cavity supply can limit populations of the 10-40% of bird and mammal species that require cavities for nesting or roosting. Conservation efforts aimed at cavity-using communities have often focused ...
Tree use, niche breadth and overlap for excavation by woodpeckers in subtropical piedmont forests of northwestern Argentina
(Polish Academy of Sciences. Museum and Institute of Zoology, 2020-10-19)
Studies dealing with the selection of tree species and characteristics for cavity-nesting birds are important to evaluate the abundance and quality of available resources in the environment. The aim of this study is to ...
Effects of sun exposure and vegetation cover on Woodpecker nest orientation in subtropical forests of South America
(Springer Tokyo, 2019-09-11)
Variations in the orientation behavior of Woodpecker nests can be due to environmental factors such as latitude as well as local climate conditions. In this study, the orientations of dot-fronted Woodpecker nesting cavities ...
A striking case of deceptive woodpecker colouration: the threatened helmeted woodpecker dryocopus galeatus belongs in the genus celeusEin Fall verblüffend irreführender Spechtfärbung: der bedrohte WellenohrspechtDryocopus galeatusist einCeleus
(Springer Heidelberg, 2015-07)
The Helmeted Woodpecker Dryocopus galeatus is a threatened species of the Atlantic Forest in southeastern South America. It has traditionally been placed in the genus Dryocopus, but it shows similarities in plumage and ...
Lethal Agonistic Behavior between Two Male Magellanic Woodpeckers Campephilus magellanicus Observed in the Cape Horn Area
(Wilson Ornithological Soc, 2016)
Agonistic behavior in woodpeckers has been described for a wide range of species, although previous studies have not reported aggressive encounters resulting in the death of adults. In this study, we provide the first ...
Spatial analysis of sap consumption by birds in the Chaco dry forests from Argentina
(Csiro Publishing, 2011-08)
Sap is a resource of high energy content that is usually inaccessible to birds, although woodpeckers have the ability to drill into living trees to obtain sap. Because spatial patterns of resource availability influence ...
