“…Crawl traps provide a passive method of collecting many arthropod groups crawling on tree boles and have been used successfully to study the overall arthropod community associated with tree boles (Moeed and Mead 1983, Hanula and Franzreb 1998, Hanula and New 1996, Hanula et al 2000a. However, previous studies have shown that red-cockaded woodpeckers select relatively few, common arthropods (Beal 191 1, Harlow and Lennartz 1977, Hanula and Franzreb 1995, Hess and James 1998, Hanula and Engstrom 2000, Hanula et al 2000a and that prey selection is related to prey availability (Hanula and Horn 2004). Pechacek and Kristin (2004) found that three-toed woodpeckers (Picoides tridactylus) also consistently selected a narrow range of prey (spiders and beetle larvae) even though other groups were available.…”

“…We were especially interested in monitoring changes in wood cockroach abundance because they constitute a high proportion of the woodpecker's diet on the Savannah 1 River Site and elsewhere (Hanula and Franzreb 1995, Hanula and Engstrom 2000, Hanula et at. 2000b.…”

“…Previous studies showed that wood cockroaches comprise 50% or more of the red-cockaded woodpecker nestling diet in a variety of locations and pine habitats (Hanula and Franzreb 1995, Hanula and Engstrom 2000, Hanula et al 2000b. Crawl traps collected more than 2800 wood cockroaches over the course of 24 months.…”

This study determined if short-term removal of coarse woody debris would reduce prey available to red-cockaded woodpeckers (Picoides borealis Vieillot) and other bark-foraging 1 birds at the Savannah River Site in Aiken and Barnwell counties, SC. All coarse woody debris was removed from four 9-ha plots of mature loblolly pine (Pinus taeda L.) in 1997 and again in 1998. We sampled arthropods in coarse woody debris removal and control stands using crawl traps that captured arthropods crawling up tree boles, burlap bands wrapped around trees, and cardboard panels placed on the ground. We captured 27 orders and 172 families of arthropods in crawl traps whereas 20 arthropod orders were observed under burlap bands and cardboard panels. The most abundant insects collected from crawl traps were aphids (Homoptera: Aphididae) and ants (Hymenoptera: Forrnicidae). The greatest biomass was in the wood cockroaches (Blattaria: Blattellidae), caterpillars (Lepidoptera) in the Family Noctuidae, and adult weevils (Coleoptera: Curculionidae). The most common group observed underneath cardboard panels was lsoptera (termites), and the most common taxon under burlap bands was wood cockroaches. Overall, arthropod abundance and biomass captured in crawl traps was similar in control and removal plots. In contrast, we observed more arthropods under burlap bands (mean & SE; 3,021.5 k 348.6, P = 0.03) and cardboard panels (3,537.25 k 432.4, P = 0.04) in plots with coarse woody debris compared with burlap bands (2325 + 171.3) and cardboard panels (2439.75 + 288.9) in plots where coarse woody debris was removed. Regression analyses showed that abundance beneath cardboard panels was positively correlated with abundance beneath burlap bands demonstrating the link between abundance on the ground with that on trees. Our results demonstrate that short-term removal of coarse woody debris from pine forests reduced overall arthropod availability to bark-foraging birds.

“…Adult forms of aquatic insects such as mosquitoes and mayflies make up the diet of the gray bat (Myotis grisescens, Tuttle 1976, LaVal et al 1977. Wood roaches (Blatellidae), adult and larval forms of beetles, and larval moths are important components of the red-cockaded woodpecker diet (Hanula et al 2000). All the avian species also forage for spiders (Pulick 1976, Hanula et al 2000, Repasky and Doerr 1991.…”

All the avian species also forage for spiders (Pulick 1976, Hanula et al 2000, Repasky and Doerr 1991. Insect eggs are also significant prey of the bird species, particularly the vireos and warbler (Pulick 1976), which is of particular concern given the ovicidal activity of lubricating oils.…”
