With the forecast looking fantastic on Sunday night I finished up some family commitments and headed out to Bunyip State Park to look for some owl action. I arrived out there about 7:30 pm to still conditions and crystal clear skies. Jupiter was close to the moon which was half full and providing plenty of ambient light for moving around. Basic plan for the evening was to visit 4 sites in the park – two well known and two new sites – twice each to chase owls which should be quite vocal right now. I started at a nice known spot of mine where recently I have had Sooty and Powerful owl as well as the three regular gliders but all I had was silence. Despite a fair bit of poking around I could not even raise a ringtail. I moved on to another known spot where I had previously seen Masked Owl and sure enough after about 10 minutes I had strong call response several times but could not move the bird from its location in the forest across the valley.
I drove around a bit with only the occasional Greater Glider spotlit and the odd boobook calling for company plus numerous Geocrinia victoriana until I eventually had a Sooty Owl fly across the road in front of the car which is the first time this has happened for me. I stopped and could hear the Sooty moving away calling as it went before settling several hundred meters away. I tried to call it back but it would not come any closer. The reason for this was soon apparent as a pair of Powerful Owls started calling with the deep male in response to the higher pitched female. I was alerted to the Powerful Owl sitting above me by a number of Yellow-bellied Gliders calling raucously with one even gliding into the tree beside the owl and charging up the trunk. I had read about this behaviour from Yellow-bellied Gliders and while I had heard and seen them respond to Sooty Owl calls this is the first time I had witnessed the mobbing behaviour. Despite this the Powerful Owl sat completely unperturbed looking down at me allowing me to take a few happy snaps. By now a second Sooty Owl had joined the first as they sat screaming with indignation the gully over which the owl ignored. After 10 minutes the owl had not moved so I left it to its own devices – for all I know it is sitting there still. A couple more Greater Gliders and a Frogmouth on the way out rounded it off. All in all a pretty good night and home in bed just after 11 which is not bad for a school night!
