Abstract
About the nocturnal vocal activity of an Eurasian Eagle-Owl Bubo bubo pair during the mating season in the northern Jura Mountains in Switzerland. During 64 consecutive nights from 28 January until 2 April 2017, I surveyed the nocturnal vocal activity of a Eurasian Eagle-Owl pair in the northern Jura Mountains in Switzerland with an acoustic logger system. The most frequent calls were the male hoot and the female croaking call. Vocal activity was most intense during the first hour after sunset. Thereafter, the birds became relatively quiet for several hours. Vocal activity rose again in the second half of the night and reached another, albeit smaller, peak in the last hour before sunrise. These results are consistent with those of two other studies. Based on the data, the best time of the day for acoustic surveys of Eagle-Owl pairs in the mating season is the hour after sunset.
