Our weekly tern surveys at Caloundra produced a large haul of birds last Thursday 18-1-01, as follows:
TOTAL NUMBER OF SPECIES
TOTAL NUMBER OF BIRDS
We were unable to ID the 12,210 terns by species because of distance, but they were definitely terns coming in from the sea to roost on the sandbanks.
But why so many so suddenly? A storm was looming, and we pondered the possibility of this being an influence. Perhaps their target fish were schooling off Caloundra and the storm sent them for cover? The storm hit Caloundra about 10 minutes after sunset, and we had to pack up. Terns were still flying in in droves as we packed up. Or perhaps the Common Terns which settle further south during the summer are starting to move north prior to their migration to the northern hemisphere?
There was one orange-flagged Common Tern - right tarsus. Linda, a copy of this is going to Clive Minton.
Has anyone started to notice a drop off of Common Terns in Victoria yet? Any wise comments?
