“…The number of studies focusing on vertebrates was also rather high considering their comparatively low species number and their limited role in the decomposition process. Based on this information, a number of conservation strategies target vertebrate species, particularly birds, e.g., the white-backed woodpecker Dendrocopos leucotos, which are considered umbrella species for the conservation of dead-wood habitats, particularly snags (e.g., Arnett et al, 2010;Roberge et al, 2008).…”

“…While snags and wolf trees are used for nesting by some cavity users, live large aspen with high canopies and multiple conks should be targeted as 'wildlife trees'. Topping live trees is a common practice for creating snags however it is unlikely these 'snags' will be suitable for cavity excavation by black-capped chickadees for several years (Arnett et al, 2010). Thus, operators should retain snags that meet chickadee nest-site requirements.…”

“…As primary cavity excavators, woodpeckers are foundational links in nest web communities [17] because the cavities they create are used by dozens of other vertebrate species, and their cavities are resources from which those secondary users would otherwise be excluded [18]. Woodpeckers are known to carry fungal spores on their bills and feathers [19], and can facilitate fungal colonization of wood substrates as well [20].…”

Most diurnal birds are presumed visually sensitive to near ultraviolet (UV) wavelengths, however, controlled behavioral studies investigating UV sensitivity remain few. Although woodpeckers are important as primary cavity excavators and nuisance animals, published work on their visual systems is limited. We developed a novel foraging-based behavioral assay designed to test UV sensitivity in the Pileated Woodpecker (Dryocopus pileatus). We acclimated 21 wild-caught woodpeckers to foraging for frozen mealworms within 1.2 m sections of peeled cedar (Thuja spp.) poles. We then tested the functional significance of UV cues by placing frozen mealworms behind UV-reflective covers, UV-absorptive covers, or decayed red pine substrates within the same 1.2 m poles in independent experiments. Behavioral responses were greater toward both UV-reflective and UV-absorptive substrates in three experiments. Study subjects therefore reliably differentiated and attended to two distinct UV conditions of a foraging substrate. Cue-naïve subjects showed a preference for UV-absorptive substrates, suggesting that woodpeckers may be pre-disposed to foraging from such substrates. Behavioral responses were greater toward decayed pine substrates (UV-reflective) than sound pine substrates suggesting that decayed pine can be a useful foraging cue. The finding that cue-naïve subjects selected UV-absorbing foraging substrates has implications for ecological interactions of woodpeckers with fungi. Woodpeckers transport fungal spores, and communication methods analogous to those of plant-pollinator mutualisms (i.e. UV-absorbing patterns) may have evolved to support woodpecker-fungus mutualisms.Published by Elsevier Inc.
