Wow Carl! That is cool!

I was intrigued by the small birds' reaction - they wouldn't often see a jaeger 
so was it a reaction to the predator bird's behaviour, or a general reaction to 
an unknown predator?

Thanks, Janine

Hi Janine,

Had a similar experience here at Gorokan, NSW Central Coast some years  
ago. I was sitting in the back yard, with only the usual chatter from  
the local birds, when there was a raptor alert from the Noisy Miners  
followed by several other species. at the peak of the ruckus, a  
Pomarine Jaeger sailed over low.

Small rodents are their main prey on their nesting grounds, so perhaps  
some occasionally get sick of fish and look for a rodent takeaway.

I think its amazing how well we humans come to understand the alarm  
calls of our local birds.

Recently I was out for a run in my local park in port Melbourne when I  
heard the 'Raptor above' alarm go up. Without thinking I looked up,  
searched the dark, stormy skies, only to see a fairly big Silver Gull.

The alarms intensified and reached proportions that I've rarely heard.  
Every small bird was involved. I was confused - this was not a  
reaction to a gull. So I kept looking in the sky thinking maybe  
something much bigger was up very high.

The gull kept circling over, and the alarms perfectly followed it. I  
got my small, fairly useless, running binoculars up. The 'gull' wasn't  
- it was darker, with longer wings, big heavy shoulders and a slightly  
wedge-shaped tail. It was a bit bigger than a Silver Gull.

Eventually it stopped circling around and disappeared. I think it was  
a Jaeger.

The wind that day was a howling Southerly, and I was only 500m from  
the beach, but even so I didn't know Jaegers hunted inland. This bird  
certainly was looking out for something and the small birds were  
highly aware of that.

I wished I'd seen more or had a camera!
