This morning about 11 a Magpie carrying 2 thin sticks in its bill flew across Athllon Drive near the intersection with Hindmarsh Drive at Woden.
 
And for the past week and half in my local area at the southern end of Gordon, the Magpies in 2 adjoining territories have started displaying aggressive behaviour towards the trio of Grey Currawongs that have been around for just over 3 weeks now. Today, the Magpies in one territory were also being aggressive towards a Pied Currawong. And in that same area a Magpie-Lark was also fluttering over and calling at the Magpies and the Pied Currawong.
 
The Pied Currawongs have been aggressive towards the Grey Currawongs, the Mapies, the Magpie-Larks, the Red Wattlebirds and anything else avian that happens to catch their eye. I am not regarding this as breeding behaviour though - it just seems normal year-round behaviour for Pied Currawongs!!!
 
The Grey Currawongs, just out of interest, don't seem to have any aggressive streak towards anything. They merely move out of the way when either the Magpies or the Pied Currawongs fly at them - and then resume foraging by picking through the fallen leaf and twig layer under the eucalypts or tearing off chunks of bark on the lower trunks of those eucalypts.
