BUCEROTIDAE Hornbills > Oriental Pied Hornbill
Click the image to enlarge
Oriental Pied Hornbill
Latin Name : Anthracoceros albirostris
Site Name : Sepilok
Photographer : SINGH HSS, Amar
Date : 2016-05-01
Notes : Saw a family unit of Oriental Pied Hornbill – adults with two juveniles. I suspect they (and Imperial Green Pigeons) had come to feed on Oli Palm fruit. They were making lots of calls. Of interest to me was the build up to calls by juveniles followed by loud additions by the adults, especially the male.
This is a full sonogram/waveform – notice the ‘hesitant’ calls by juveniles and then the fully adult entry.
