Mystery nocturnal found on SERF Sensor at 21.18hrs on 15 October 2010
This was the only call of interest between 8pm and midnight, as it rained throughout the period, frogs and insects are calling in the background. I think it may be a Powerful Owl (from experience and listening to other media) but I am certainly not 100% sure. Masked and Sooty Owls have similar cicada-like calls but are a bit quite different to my ear.
The closest call that I’ve found on the web so far (for me) is this one:
http://www.owlpages.com/sounds.php go to “10 week old Chick Begging”
but there have been many feasible suggestions including Green Tree Frog, Brown Goshawk and Forest Kingfisher
