Abstract

Playback is often used to improve recording of birds and therefore to gain more precise data on their numbers and distribution. The aim of this study was to evaluate the potential suitability of this method for survey of Hoopoes Upupa epops in Latvia. Playback was carried out in mornings between the end of April and beginning of July in a total of 36 routes, of which 33 routes (137 points) were used to analyse changes in Hoopoe activity. Hoopoes responded to playback at 11 (8 %) of the points. The results suggested that the most appropriate time for playback surveys on Hoopoes was in mornings in May. It is possible that the response behaviour of Hoopoes depends also on local breeding densities. More studies concerning their territorial behaviour are needed to fully evaluate the efficiency of the playback method for studying population size and distribution of the Hoopoe.

Key words: Hoopoe, playback, Upupa epops, territory.
