To minimize investigator-associated nest failure, nests were revisited once after hatch was expected. Nests believed to be influenced by investigator disturbance were excluded from analyses that compared habitat structure with nest success. Nest success was not independent of the time of nest location ( = 4.08, df = 1). Nests found early in the laying stage failed more often than those found later. Thus, the nest visit may have contributed to nest failure.
