Description:	Technical report Abstract: It is estimated that nearly a quarter of the remaining Red-cockaded Woodpecker (RCW) population resides on military installations in the southeastern United States. Such a close association has raised questions about the interaction between training and the conservation of Red-cockaded Woodpeckers on military land. Increased importance has been placed on determining how noise affects these species. This report presents second year results of a multiyear study to determine the effects of certain kinds of training noise on the endangered Red-cockaded Woodpecker. Preliminary data suggest that: measured levels of experimental noise from .SO-caliber blank fire and artillery simulators did not affect RCW nesting success or productivity; Red-cockaded Woodpecker flush frequency increased as stimulus distance decreased, regardless of stimulus type; woodpeckers returned to their nests relatively quickly after being flushed; and noise levels in Red-cockaded Woodpecker nest cavities were substantially louder than levels recorded at the base of the nest tree.
