Recordings of begging WISA in nest. Recorded 4 m from nest hole. In the first recording the female feeds the chicks, and in the second recording the male feeds the chicks. The high pitched sounds are right when the chicks are being fed. Over the course of about 10 minutes the chicks were fed 6 times, alternately by the female and male. The adults seemed to be foraging within a radius of 10-100 meters. Only put down three birds, because I could only see the adults, and hear at least one chick begging. No doubt there were more chicks.
