The effects of the time of day on depredation of artificial open ground nests were studied in the Szigetkoz riparian area in NW Hungary. Seventy five percent of nests placed out during daylight, and 40 % of nests placed out in twilight conditions were depredated (P < 0.05). This result showed that in areas where visual predators are abundant, which can browse after the experimenter departs, nest placement during daylight may cause an artificially high depredation rate.
