Dear birding Aussers
Jon Wren asked if anyone else had seen BFP's involved in spiralling flight.
In NZ I spent hundreds of hours studying the feeding behaviour of the BFP,
and became familiar with them spiralling upwards when they were departing
to another feeding site some distance away. If something happens to change
their mind I guess they would descend to the site they just left. Maybe
they saw dogs at the site they were intending to fly to, or that the tide
was not what they were expecting. Or maybe you had just inadvertantly
chased them off by giving them a fright, then they realised it was just
that bird counter at it again, and so recognising you as a harmless
cohabiter of the habitat, decided to return to their feeding. Maybe it was
an aerial predator that chased them, then passed on its way.
Interesting observation.
Cheers
Mike
