Powl update

[Martin Butterfield <>]

I have just used Google Earth to explore what would be covered by a circle with radius of 3.1kms (ie an area of 30 square kms centred on) Powlville.  

• Heading towards Black Mountain, basically the entire Reserve (if one can still use that term post-GDE) is within the circle. 
• So is O'Connor Ridge up to Ginninderra Drive if it goes North-Westish, so there could be something worth watching at a Brumbies game.  
• If it puts a bit of East on its North it could easily range to the Summit of Mt Ainslie (has a Powl ever been recorded munching on a Swift Parrot?)

Being the closest ( about 600 metres ) and a regular observer I will make a guesstimate of about 90 mammals including gliders, ringtail and brush tail possums plus several birds calculated on a kill every two nights for six months. The field guides provide information that a pair of powerful owls occupy a territory of 30 square kms so the hunting range is far beyond the ANBG and it has been recorded heading for Black Mountain at dusk. Perhaps one of our resident owl experts  can be forthcoming on this query Elisabeth. Regards to all T2.
