I noted a pair of pelicans flying above Monash (the
edge of Monash not far from Lake Tugg) - this is not unusual in
itself.
They were at about a height of 50 or 60 metres, and
as I watched them I saw that they were tracing circles that were offset each
time by about half the diameter, so that they gradually tracked towards Kambah.
Their path, if you were able to record it somehow, would have been a
lengthening coil. A very inefficient way to get anywhere!
My initial thought was they were trying to catch an
updraft off the Monash ridge that extends into Oxley, but their altitude didn't
seem to change much. Then I thought they were surveying or memorising the
countryside for some later purpose, and my final thought was that they were just
enjoying their own company and flying without having any pressing
destination.
Can anyone shed any light on this mode of
flight?
