Pileated Woodpeckers (Dryocopus pileatus) cause damage to Red-cockaded Woodpecker (Picoides borealis) cavity trees in the form of cavity enlargement or other excavations on the surface of the pine tree. However, it is not known whether Pileated Woodpeckers excavate more frequently on Red-cockaded Woodpecker cavity trees than on...

We observed interactions between a nesting pair of pileated woodpeckers (Dryocopus pileatus) and what appeared to be four pairs of wood ducks (Aix sponsa). Wood ducks regularly approached and attempted to enter an active pileated woodpecker nest cavity that contained three fully feathered young pileated woodpeckers. The male...

Prior to 1994, the pileated woodpecker was a management indicator species (MIS) of mature and old-growth forest conditions on 16 of 19 national forests in the Pacific Northwest Region. This status required each of those national forests to establish pileated woodpecker habitat areas that included tracts of mature and old-growth forest with minimum densities of large,...

Providing habitat for pileated woodpeckers in the Pacific Northwest has been a key component of forest management strategies for over 20 years. We investigated the diet of pileated woodpeckers, and selection by birds of both individual structure and site characteristics for foraging. Birds foraged amost exclusively in closed-canopy habitats and selected relatively tall...

We located and studied 123 pileated woodpecker (Dryocopus pileatus) nests from 1973 to 1983 in northeastern Oregon. Pileated woodpeckers excavated nest cavities in late March and early April, incubated eggs as early as 13 May and as late as 15 June, and fledged young between 26 June and 13 July. These birds nested at 1 year of age, and some lived...

To determine the short-term effects (1 to 3 years posttreatment) of fuel reduction on pileated woodpeckers (Dryocopus pileatus) in northeastern Oregon, we compared measures of abundance of logs, snags, stumps, and of woodpecker foraging in mixed-conifer stands that had undergone the following treatments: prescribed burning after mechanical fuel...

Knowledge of the survival of the Pileated Woodpecker (Dryocopus pileatus) is essential in managing viable populations of the species. In eight study areas in northeastern Oregon, survivorship of adult Pileated Woodpeckers was 0.60 after 6 mo, 0.47 after 12 me, and 0.35 after 18 mo. Of three juveniles radio-tagged in late summer or fall, two...

The pileated woodpecker is a species of conservation concern and a keystone species in mature and old forests of the Pacific Northwest. In the Blue Mountains of northeast Oregon, researchers from the PNW Research Station in La Grande, Oregon, studied the effects of natural and human-caused disturbance on pileated populations and their habitat over a period spanning...

A computer simulation approach (DYNAST) was used to evaluate effects of three timber-management alternatives on wildlife in a 2700-ha (6700-acre) study area located in the Sierra Nevada, California. Wildlife species selected to evaluate the effects of these alternatives were band-tailed pigeon (Columba fusciutu), pileated woodpecker (

We studied woodpecker foraging behavior, snag quality, and surrounding habitat in a bottomland hardwood forest in the Stephen F. Austin Experimental Forest from December 1984 through November 1986. The amount and location of woodpecker foraging excavations indicated that woodpeckers excavated mainly at the well-decayed tops and bases of snags. Woodpeckers preferred to...

Conservation of species associated with mature forest habitats remains an important objective for non-federal lands in the Pacific Northwest. With few exceptions, state forest practices rules, a Washington state pilot landscape planning program, and federal Habitat Conservation Plans provide little functional habitat for species, like the Pileated Woodpecker (Dryocopus...

An old-strucutre stand with large amounts of tree mortality was treated to accelerate regeneration and reduce fuel loads but still maintain its function as old growth for selected bird species. The small-diameter (

Since 1965, the U.S. Fish and Wildlife and Canadian Wildlife Services have sponsored annual Brceding Bird Surveys (BBSs), which are done in the United States and Canada using standard procedures. Data resulting from individual surveys may have Cptential to answer certain management questions or serve to fill information gaps for relatively small geographic areas. A BBS...

Over a 13-year period we examined the mortality of cavity trees (n = 453) used by red-cockaded woodpeckers (Picoides borealis) on national forests in eastern Texas. Bark beetles (53%), wind snap (30%), and fire (7%) were the major causes of cavity tree mortality. Bark beetles were the major cause of mortality in loblolly (Pinus taeda...

A study was undertaken to develop methods for extensive inventory and analysis of wildlife habitats. The objective was to provide information about amounts and conditions of wildlife habitats from extensive, sample based inventories so that wildlife can be better considered in forest planning and policy decisions at the regional scale. The new analytical approach...
