    A Revision of the Mexican Piculus (Picidae) Complex

    THE WILSON BULLETIN A QUARTERLY MAGAZINE OF ORNITHOLOGY Published by the Wilson Ornithological Society VOL. 90, No. 2 JUNE 1978 PAGES 159-334 WilsonBdl., 90(Z), 1978, pp. 159-181 A REVISION OF THE MEXICAN PZCULUS (PICIDAE) COMPLEX LUIS F. BAPTISTA The neotropical woodpeckers of the genus Piculus are closely related to the flickers (Colaptes) (Short 1972). P icu 1us species range from Mexico to southern Brazil, Paraguay, Peru (Ridgway 1914) and Argentina (Salvin and Godman 1892). Peters (1948) lists 46 taxa (9 species and their sub- species) of which 20 are subspecies of Piculus rubiginosus, the most widely distributed species. The latter ranges from southern Veracruz to the north- western provinces of Jujuy, Salta, and Tucuman in Argentina (Peters 1948). Compared with other picids, this genus is generally poorly represented in museum collections. It is possible that they are not as rare as they seem, but being rather silent and secretive birds and difficult to distinguish from the associated vegetation due to their cryptic green coloration, are easily passed unnoticed by collectors in the field. A difference of opinion exists among taxonomists regarding the status of several of the Mexican forms. Two species complexes are recognized in the Mexican check-list (Miller et al. 1957). The Piculus auricularti complex is reported by these authors as consisting of 2 subspecies: sonoriensis known only from the type series of 3 birds taken at Ranch0 Santa Barbara, Sonora, and the nominate race auricularis recorded as ranging from Sinaloa south to Guerrero. They point out the uncertain status of the form sonorien- sis, stating that additional material is needed to substantiate it.

Belthoff 1 1Department of Biological Sciences and Raptor Research Center, Boise State University, Boise, Idaho, USA, 2Biology Department, College of William and Mary, Williamsburg, Virginia, USA ABSTRACT. Few studies have examined the patterns of co-occurrence between diurnal birds such as woodpeckers and nocturnal birds such as owls, which they may facilitate. Flammulated Owls (Psiloscops flammeolus) and Northern Saw-whet Owls (Aegolius acadicus) are nocturnal, secondary cavity-nesting birds that inhabit forests. For nesting and roosting, both species require natural cavities or, more commonly, those that woodpeckers create. Using day and nighttime broadcast surveys (n = 150 locations) in the Rocky Mountain biogeographic region of Idaho, USA, we surveyed for owls and woodpeckers to assess patterns of co-occurrence and evaluated the hypothesis that forest owls and woodpeckers co-occurred more frequently than expected by chance because of the facilitative nature of their biological interaction. We also examined co-occurrence patterns between owl species to understand their possible competitive interactions. Finally, to assess whether co-occurrence patterns arose because of species interactions or selection of similar habitat types, we used canonical correspondence analysis (CCA) to examine habitat associations within this cavity-nesting bird community.

    Wildland Fire in Ecosystems: Effects of Fire on Fauna

    United States Department of Agriculture Wildland Fire in Forest Service Rocky Mountain Ecosystems Research Station General Technical Report RMRS-GTR-42- volume 1 Effects of Fire on Fauna January 2000 Abstract _____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, stand- replacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines. Keywords: fire effects, fire management, fire regime, habitat, succession, wildlife The volumes in “The Rainbow Series” will be published during the year 2000.

    NORTHERN FLICKER (Colaptes Auratus) Guidance for Conservation

    NORTHERN FLICKER (Colaptes auratus) Guidance for Conservation The Northern Flicker is a common, but declining in open woodlands in the Hudson River Valley. Conservation Status Partners in Flight regards this bird as a Species of Regional Concern in Bird Conservation Regions 13, 28, and 30. Breeding Bird Survey show a moderate decline in populations statewide since 1966. Breeding Bird Atlas data show a slight reduction in its distribution in the Hudson River Valley, but overall remains very common. Identification This medium-large woodpecker is brown overall with barring on the back and wings, off-white underparts with black spots, and a black bib. Its underwings and undertail are yellow. It has a white rump patch that is noticeable when the bird is flying. The male has a black stripe behind the beak. It can be easily identified in flight by a distinctive, undulating flight pattern. Its most-often-heard call is a whinnying sound that somewhat A. Wells resembles laughter. It also gives a call that is often transcribed as “klee-yer.” Habitat Flickers are ground-foraging woodpeckers that nest in tree cavities. It can be found in open deciduous, mixed, and coniferous woodlands, forest edges, riparian woodlands, beaver ponds and other wetlands with standing trees, meadows, parks, as well as urban and suburban areas, and farm woodlots with large trees. It requires cavity nest sites in dead or dying trees along forest edges or in open woodlands. The cavities it excavates can later be used by other hole-nesting birds. Food This species most often forages on the ground by probing and hammering in the soil with its bill, where it eats mainly ants, but also beetle larvae, grasshoppers, and wasps.
