The Woodpecker, can share our state. occurrence of Black-backed Woodpeckers in Michigan during the MBBA II period is probably quite representative of the overall nature of this species’ breeding habits. There was evidence of low level populations across much of upper Michigan and in one location, in one year, there was a super-abundance. The Black-backed Woodpeckers nesting on the Baraga Plains in Baraga County in 2008 were among the densest ever reported for that species (Dixon and Saab 2000). But that super- abundance was a temporary phenomenon related to the forest fire that Black-backs have evolved to exploit. Such small scale, short-term (two to four year) breeding hotspots have probably always occurred in Michigan. Black- backed Woodpeckers have always been an uncommon to rare species, inhabiting their rather small niche in the ecology of Michigan’s forests and they seem ready to continue to do so. In both atlases the Black-backed Woodpecker was found in about 3.5% of townships statewide. © 2010 Kalamazoo Nature Center Black-backed Woodpecker (Picoides arcticus) Joseph Youngman Status: Special Concern MNFI Literature Cited Suggested Citation Benzie, J.W. 1977 Manager’s handbook for Youngman, Joseph. 2011.

  • The Generic Distinction of Pied Woodpeckers
    THE GENERIC DISTINCTION OF PIED WOODPECKERS M. RALPH BROWNING, 170 JacksonCreek Drive, Jacksonville,Oregon 97530 ABSTRACT: The ten speciesof New World four-toedwoodpeckers (scalaris, nuttallii, pubescens, villosus, stricklandi, arizonae, borealis, albolarvatus, lignarius,and m ixtusand the two borealthree-toed species (arcticus and tridactylus), currentlycombined in the genusPicoides, differ, in additionto the numberof toes,in modificationsof the skull,ribs, the belly of the pubo-ischio-femoralismuscle, head plumage,and behavior. I recommendthat the genericname Dryobates be reinstituted for the New World four-toedwoodpeckers. There are three generalmorphological groups of pied woodpeckers,a groupof nine four-toedspecies of the New World, a groupof 22 four-toed speciesof the Old World, and a groupof two three-toedspecies straddling bothregions. ! referto thesegroups of piedwoodpeckers beyond as the New World,Old World,and three-toedgroups. The three-toedspecies have long beenin the genusPicoides Lac•p•de, 1799, but the four-toedgroups have been combinedat the genericlevel in differentways. All four-toedpied woodpeckerswere long includedin the genusDryobates Boie, 1826, later changed to Dendrocopos Koch, 1816 an earlier name (Voous 1947, A.O.U. 1947, Peters 1948). Despite the differencein number of toes, Dendrocoposwas combined with Picoidesbecause of generalsimilarities in anatomy (Delacour 1951, Short 1971a), plumage and behavior (Short 1974a), and vocalizations(Winkler and Short 1978). The A.O.U (1976) followedthis mergerof the genera.On the basisof skeletalcharacters Rea (1983) was skepticalof the merger,but he did not providedetails. On the otherhand, Ouellet(1977), concludingthat the two generadiffer in external morphologyand some behaviors and vocalizations, separated the Old World four-toedwoodpeckers in Dendrocoposand three-toedand New World four-toedwoodpeckers in Picoides.The A.O.U.

  • Hairy Woodpecker (Picoides Villosus)
    Hairy Woodpecker (Picoides villosus) Paul Cotter Traits of the hairy woodpecker—contrasting black and white (sometimes smoky) coloration, distinctive undulating flight, loud drumming, and willingness to come to feeders—are familiar to many observers in North American forests and woodlands (Fig 1). This species characteristically probes trees for insects, its primary food item, but also feeds on fruit and seeds. A charismatic year-round resident of Southeastern Alaska (Southeast), the hairy woodpecker can be observed in all forested areas of the Tongass National Forest (Gabrielson and Lincoln 1959). In the Tongass, as elsewhere, hairy woodpeckers are primary excavators; they hollow out their nests in trees, often in the trunk or upper regions of snags. These nests are later available for use by other wildlife species. The hairy woodpecker is associated with the varied structure of mature and old-growth forests (Jackson et al. 2002). Because the species is strongly affiliated with old-growth forest habitats, population trends of the hairy woodpecker may serve as indicators of old- growth forest health. Further, because other bird species are at least partly dependent on abandoned hairy woodpecker cavities, declines in hairy woodpecker populations may foreshadow declines in other avian species. Recently, the U.S. Fish and Wildlife Service (USFWS) has expressed interest in developing a monitoring strategy for hairy woodpeckers (M. Kissling, USFWS, Juneau, AK, FIG 1. A male hairy woodpecker at a feeding site in personal communication 2004). The reliance of this southeastern Alaska. (Bob Armstrong) species on old-growth forest habitats for breeding and wintering makes it a logical choice for a Management Indicator Species (MIS) for measuring old-growth forest health in the Tongass.

  • Interspecific Social Dominance Mimicry in Birds
    bs_bs_banner Zoological Journal of the Linnean Society, 2014. With 6 figures Interspecific social dominance mimicry in birds RICHARD OWEN PRUM1,2* 1Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT 06520-8150, USA 2Peabody Natural History Museum, Yale University, New Haven, CT 06520-8150, USA Received 3 May 2014; revised 17 June 2014; accepted for publication 21 July 2014 Interspecific social dominance mimicry (ISDM) is a proposed form of social parasitism in which a subordinate species evolves to mimic and deceive a dominant ecological competitor in order to avoid attack by the dominant, model species. The evolutionary plausibility of ISDM has been established previously by the Hairy-Downy game (Prum & Samuelson). Psychophysical models of avian visual acuity support the plausibility of visual ISDM at distances ∼>2–3 m for non-raptorial birds, and ∼>20 m for raptors. Fifty phylogenetically independent examples of avian ISDM involving 60 model and 93 mimic species, subspecies, and morphs from 30 families are proposed and reviewed. Patterns of size differences, phylogeny, and coevolutionary radiation generally support the predic- tions of ISDM. Mimics average 56–58% of the body mass of the proposed model species. Mimics may achieve a large potential deceptive social advantage with <20% reduction in linear body size, which is well within the range of plausible, visual size confusion. Several, multispecies mimicry complexes are proposed (e.g. kiskadee- type flycatchers) which may coevolve through hierarchical variation in the deceptive benefits, similar to Müllerian mimicry. ISDM in birds should be tested further with phylogenetic, ecological, and experimental investigations of convergent similarity in appearance, ecological competition, and aggressive social interactions between sympatric species.

  • Hairy Woodpecker Picoides Villosus
    Hairy Woodpecker Picoides villosus Folk Name: Sapsucker Status: Resident Abundance: Uncommon to Fairly Common Habitat: Forests and heavily forested neighborhoods The Hairy Woodpecker is the larger doppelganger of the Downy Woodpecker, and the fine points of differentiating between the two are provided in the account of the Downy Woodpecker (just above). The Hairy was once considered “rather common” in the Central Carolinas, but its relative abundance appears to have slowly declined in many areas over the past century as development has increased. In Charlotte in 1944, Elizabeth Clarkson designated the Hairy Woodpecker as simply a permanent resident and noted the Downy as a “common” permanent resident. the Downy Woodpecker, in order to insure the long- Forty years later, the designation remained the same for term success of their breeding population.

Background: The Fork-tailed Swift Apus pacificus was until recently (e.g., Chantler 1999, 2000) considered to consist of four subspecies: pacificus, kanoi, cooki, and leuconyx. Nominate pacificus is highly migratory, breeding from Siberia south to northern China and Japan, and wintering in Australia, Indonesia, and Malaysia. The other subspecies are either residents or short distance migrants: kanoi, which breeds from Taiwan west to SE Tibet and appears to winter as far south as southeast Asia.

  • American Three-Toed Woodpecker Picoides Dorsalis
    American Three-toed Woodpecker Picoides dorsalis Aves — Piciformes — Picidae CONSERVATION STATUS / CLASSIFICATION Rangewide: Secure (G5) Statewide: Imperiled (S2) ESA: No status USFS: Region 1: No status; Region 4: Sensitive BLM: No status IDFG: Protected nongame BASIS FOR INCLUSION Unknown population trend in Idaho; habitat threats. TAXONOMY New World dorsalis and Old World tridactylus populations of three-toed woodpeckers were recently split (American Ornithologists’ Union 2003) on the basis of differences in mitochondrial DNA (Zink et al. 1995, 2002) and voice (Winkler and Short 1978, Short 1982). Originally considered to be separate species, the merger of New World dorsalis into Old World tridactylus (e.g., American Ornithologists’ Union 1931, Peters 1948) was never explained (American Ornithologists’ Union 2003). Hence, the American three- toed woodpecker (P. dorsalis) is once again considered a separate species from the Eurasian three-toed woodpecker (P. tridactylus). Based upon differences in both size and the amount of white on the back, 3 subspecies are recognized: P. d. dorsalis, P. d. fasciatus, and P. d. bacatus (Leonard 2001). The subspecies that occurs in Idaho is likely the P. d. fasciatus although a zone of integration has been noted between P. d. fasciatus and P.d. dorsalis in northern Montana (Leonard 2001). DISTRIBUTION AND ABUNDANCE American three-toed woodpecker distribution generally follows the distribution the boreal forest region, and this species is the only species of woodpecker to occur in both the Nearctic as well as the Palearctic (Leonard 2001). American three-toed woodpeckers occur as far north as Alaska, and extend through the boreal forests of Canada south into the lower 48 states.

Picoides and Dendrocopos are two closely related genera of woodpeckers (family Picidae), and members of these genera have long been the subjects of phylogenetic debate. Mitochondrial cytochrome c oxidase subunit I (COI) is a powerful marker for the identification and phylogenetic study of animal species. In the present study, we analyzed the COI barcodes of 21 species from the two genera, and 222 variable sites were identified. Kimura two-parameter distances were calculated between barcodes. The average interspecific genetic distance was more than 20 times higher than the average intraspecific genetic distance. The neighbor-joining method was used to construct a phylogenetic tree, and all of the species could be discriminated by their distinct clades. Picoides arcticus was the first to split from the lineage, and the other species were grouped into two divergent clades. The results of this study indicated that the COI genetic data did not support the monophyly of Picoides and Dendrocopos.

  • Taxonomy of Picoides Pubescens (Downy Woodpecker) from the Pacific Northwest M
    TAXONOMY OF PICOIDES PUBESCENS (DOWNY WOODPECKER) FROM THE PACIFIC NORTHWEST M. RALPH BROWNING1 A b s t r a c t . — Three subspecies of Picoides pubescens (Downy Woodpecker) are currently recognized in the Pacific Northwest (Peters 1948; American Ornithologists’ Union [A.O.U.] 1957; Short 1982; Winkler et al. 1995): gairdnerii Audubon, 1839 (type locality: no locality given = Fort Vancouver, WA; but see beyond) from southwestern British Columbia to western Washington, Oregon, and Mendocino County in northwest­ ern California; turati Malherbe, 1860 (near Monterey, CA ) from north-central Washing­ ton to central Oregon and north-central interior and humid coastal California; and leucurus Hartlaub, 1852 (Rocky Mountains) from the Kenai Peninsula, Alaska, to British Colum­ bia east of the coastal mountains, eastern Washington and Oregon, northeastern Califor­ nia, Nevada, Arizona, and New Mexico, east to Montana, and Nebraska. The subspecies gairdnerii has been characterized as darker below than other subspecies, with the wing coverts unspotted (Short 1982) or with the coverts mostly un­ spotted (Winkler et al. 1995). However, almost all birds from Vancouver Island, British Columbia, and many from the southern parts of the range of gairdnerii have white spots on the tertials and coverts. The presence of tertial spots on specimens from southern Vancouver Island is a character ascribed to P. p. fum idus, an unrecognized (A.O.U. 1890) subspecies proposed by Maynard (1889). Specimens of gairdnerii, compared with turati, are said to be larger (Winkler et al. 1995) and by as much as 5–8% (Short 1982), but the elements used for size comparisons by these authors was not indicated.
