    Abstract: The purpose of this study was to investigate the influence 
  of begging call playback on the behavior of great tit (<I>Parus major</I>) parents 
  with varying intensities of begging calls played from artificial nest boxes. 
  Mean number of feeding visits by parents did not differ among control and both 
  playback treatments. Mean feeding time was longer in the playback 1 (80 dB) 
  group than in the control (60 dB) or playback 2 (100 dB) groups. The first open-mouthed 
  nestling was more frequently fed than other nestlings in all control and treatments. 
  In this study, parents did not respond to short-term increases in overall begging 
  intensity. Further investigations of nestling begging and parental care behaviors 
  would reveal much about the interaction between great tit parents and nestlings.
