When Sea Eagles snatch up swan cygnets I momentarily hate them and threaten to 
cancel my subscription to Sea Eagle Cam but I had no idea they'd feed on 
seagull.
So why then, are there so few Sea Eagles and an abundance of Gulls????
ALSO:
 
The Black Swan Communal Nesting Site at Paynesville, (Gippsland Lakes) has its 
first occupants for this season with 3 nests occupied.   At nest #1 both mum & 
dad were in the water today and I saw a white (???????) seabird swoop down and 
steal an egg and started eating the yellow contents in about 6 inches of water 
by the lake edge.  Dad came by and after having a taste of the contents 
himself, washed the contents out of the egg shell and threw it into deeper 
water.

Obviously my first question is,  What is the name of the white seabird that 
looks like a plain seagull on steroids, (about twice the size) like a dwarf 
Albatross ????
Also, why do black swans leave their nests to chastise harmless juvenile swans 
yet pay no attention to egg stealing preditors ???
Is it an experience thing?  I notice the other two nests are never left 
unattended.
