1 Adult Female
1 Adult Male
Scene near nest with young: male with food calls female, then utters call of uneasiness (probably because of my presence). After a few further calls, the female answers with a begging call ("siiii"). Transfer of food seems disturbed by my presence, since it takes a long time. (Thunderstorm comes up). After some begging , calls of the female we bgin to hear those of the young in the nest (shorter and clearer than female's). Once more, male in background and female very close (begging), different bibbering notes (most in connection with food transfer).
