I was really keen to put up yet another Wagtail Nursery set, as we’ve several along the river at the moment.

But perhaps a change is a good thing, so here’s a Swamp Harrier.
Perhaps the most challenging of the raptors that we work with.  These birds are have a zero tolerance policy when it comes to humans, and most often what we see is the white tail feathers of a Swampie disappearing in front of us.

This one came up the paddock toward us, but was searching for an updraft and as soon as it reached it the bird rose at a great rate with hardly a flick of the wings.

Which caused me to ponder that little bit, that how do they sense where the updrafts are happening?  Eagles, Pelicans, Kites, Ibis and many others seem to be able to work their way along and then rise with the thermal.

Unknown, but still things that make going out and watching a most pleasing experience.
