觀察細節
Listening for Nankeen night herons after dusk. Many calls from multiple trees where they are known to roost although they have been absent from this site since October, presumably away breeding. There were almost certainly more than four but I was unable to be sure I was not counting some birds twice. The attached sound file has been extracted by Peter Frost from my night time mobile phone video and some calls have been closed up to remove lengthy silences.
