Bearded Tit (Panurus biarmicus) Science Article 1
abstract
Although the European population of Bearded Tit Panurus biarmicus is largely sedentary, there have been only a few studies of Bearded Tits outside the breeding season. The camouflaging effect of their habitat (reedbeds) and their reduced vocal activity are the main difficulties presented during this time (Wawrzyniak and Sohns 1986). Nevertheless, studies outside the breeding season may be crucial for monitoring changes in the numbers and range of the Bearded Tit population (Gosler & Mogyorosi 1997). In this study of Bearded Tits outside the breeding season, the efficiency of undertaking point counts that were combined with playback was assessed in comparison with traditional methods.
