Right in the centre of this picture (slightly worse quality as I've zoomed in) is an osprey nest on top of a pylon. It currently has both adults and one osprey chick sitting in it who peeps every so often especially if a Brahminy kite flies overhead, which I think they have been! The only thing we're missing is a pair of binoculars so I can't be sure!
Addition to post: just seen two more nests on the way home, also on telegraph poles! Couldn't see the young just the adults, but apparently they do have chicks.
