Over 5 years we have followed the nocturnal haunts of 20 @UrbanPowerfuls 🦉These magnificent owls are threatened by urbanisation so it’s more important than ever to understand the space they need. I’ll show you 4 ranges that highlight variability in their movements #SCBMelb20 1/5
We’ve found all owls align movements very closely to high NDVI/tree cover with an avoidance of low NDVI/high urbanisation. Tree cover is important because these owls are arboreal hunters, will roost in dense vegetation and need large old trees for hollows. #SCBMelb20 #moveVis 2/5
On average owls travel 4.6km a night, but this does vary! This owl travelled 47km over 2 nights! She was possibly looking for a mate highlighting the need for good connectivity between habitat patches to allow urban wildlife to move #SCBMelb20 #moveVis 3/5
In comparison, some @UrbanPowerfuls will move <100m a night if there is good habitat with lots of prey like possums. In these situations, we've found territories can be closer together & tolerate some overlap with neighbouring pairs #SCBMelb20 #moveVis 4/5
We work closely with Melb. councils, @ParksVictoria and concerned groups to better understand habitat requirements and suggest management outcomes because owls can spend a lot of time on private property. It’s up to you to supplement owl habitat! #SCBMelb20 #moveVis 5/5
