Banjo has always chased birds. Any bird. The most fun are those swifts - swallow like birds - because they are so fast and just fly round and round in big circles low to the ground. The most excellent exercise! But we haven't seen them at our dog walking spot for a while. Magpies are fun if they chase her back. Fun for me to watch anyway. Most of the other birds are boring as they just fly to the nearest tree.
Except for the galahs. They will often take off fairly slowly, and either land a bit further and take off again or fly around in a big circle. Making lots of noise. And Banjo just runs and runs after them until the birds get fed up and land on the power lines or until I call her. I imagine that she thinks that the birds are actually playing a game of chasie with her and it often actually looks like that too. They seem to slow down to let her catch up and then speed up again. It is the best exercise for her if there are no dogs to play with. Especially because the galahs fly in circles so there's not the risk of Banjo wanting to follow them across the road or running too far away. Though she easily runs round the whole big oval a few times.
My old dog used to chase them when she was young and I just love the sight and sound of a big flock of galahs circling the oval and seeing the pink-grey-pink-grey with every turn.
And lately I've noticed that the local magpies and peewees will let Banjo run right past them when she is chasing the galahs. They seem to know that she won't show any interest in them. Pretty stoic birds to stay put when she seems to be running straight at them at full speed!
Sorry, that was probably an utterly boring story to most of you, but I love that kind of stuff...
