White-bellied Sea-eagle Observations & Queries (NSW)

[Philip Veerman <>]

Maybe unusual, as in generally seen singly or pairs but probably not overly so. Among related species (same genus) it is easy to find photos of Bald Eagles and Steller’s Sea Eagles in significant gatherings. Last time I was in Tasmania (2003) for the RAOU congress or whatever it was called, I recall seeing a gathering of about 10 White-bellied Sea-Eagles within about one or 2 hectares, somewhere close to Port Arthur. I don’t know anything about connections between them of course. It was just a visit. HANZAB V2 page 87 gives a few other examples.

Sharing an observation from a camping trip to Bittangabee Bay NSW this past week, and some queries. 

 

Attached are two photos - one of 3 adult White-bellied Sea-eagles sharing a perch, the other of 2 juveniles sharing a tree, all taken in the same area.

 

Over a number of days in this small area I observed: 2 young with 2 adults, a single juvenile with 2 adults, and a single juvenile with 3 adults.

 

The sighting of three adults sitting so close together seems unusual? 

I also assume it is likely the birds are all from one family and at some times members of the family were elsewhere looking for food etc. Or could the area be being used by multiple families?

At no time did I see the juvenile(s) and adults on the same perch, usually there was 20-50m between them. Is this typical as the birds become older?

 

I'm interested in any similar observations or information, or books or other resources that would provide more information.

 

Thanks in advance

Matt
