The following questions were sent to David Hancock from Chris Rickwood:
I’ve just seen a spectacular wildlife event. It was about 2pm on Tuesday 2008-Jul-08 on White Rock’s East Beach. I heard a bird at the edge of the water giving a loud cry which sounded like “craaak”. The bird was a blue heron. It was being attacked by a bald eagle. The heron flew along the coast for a short distance and then it seemed to have found a thermal. It started circling upwards with the eagle following. By this time, two other birds had joined the fray. One was a crow and the other was a gull. Both the crow and the gull started harassing the eagle. They buzzed it but didn’t seem to make actual contact. (The eagle completely ignored them.) The heron kept rising in the thermal and slowly the eagle fell behind. Eventually the eagle gave up the chase and the crow and the gull flew away.
