Rather than copying the reference materials about these eagles into the opening posts each year, I'm going to put them here and reference them. If there are things that need updating, please let me or one of the TAs know. Thanks!

Information about the White-Bellied Sea Eagle Nest Cam Located At The Discovery Center, Olympic Park In Sydney, Australia!!

Birdlife Australia was created in 2012 from the merger of Birds Australia & Bird Observation and Conservation Australia. EagleCAM is a BirdLife Australia, Southern NSW, research project. They have been studying this pair of eagles using CCTV since 2009. Sea-EagleCAM.org is an information point for White-bellied Sea-Eagles and is reporting general information to those people world wide who are interested in the White-bellied Sea-Eagle.

Mom and Dad WBSE (Thank you liberty!)



THE CAMS

The cams (both with IR) were installed in the new nest tree in June of 2012. The Samsung PTZ is in the same location as last year, 20 metres across the treetops, but doesn’t pan quite as high as before so there are no views of the Olympic Stadium.

The Sanyo cam is in the nest tree – approx. 4-5 metres away from the bowl for a nice close-up view.

There are two mics, one in each tree. The one near the Sanyo camera is switched off at the moment. It was responsible for the extra loud radio noise. The only other thing that Geoff can try to reduce the radio noise on the mic needs to be done directly under the nest. With mum and dad in residence much of the time, we’re not sure if/when this is possible.

General Information re the WBSE chicks:

The eggs of the WBSE are usually a dull white, oval in shape measuring 55mm and are incubated by both adults over 6 weeks before hatching. .They are covered in white down when they hatch which turns to brown and although two eggs are laid, it is unusual for two to be reared successfully to fledging. One egg may be infertile or the second chick may die in the nest. If the first clutch is lost the parents may attempt a second clutch. Initially the male brings food and the female feeds the chicks but both parents feed the chicks as they grow larger. Their diet consists of mainly Fish, turtles, sea snakes, birds, possum and carrion. They fledge at 70 to 80 days old and remain in the parents' territory for up to 6 months or until the following breeding season.

HOW TO TELL MOM AND DAD APART---courtesy of liberty1998----

Dad on the left and Mom on the right


Mamma is approx. 25% bigger than dad and he is a slightly darker shade of grey.
Her eyes are a bit slanted and she has several black feathers in middle of her tail feathers.

Dad has a cleaner line at back of the neck where grey meets white.
He has lots more black tail feathers. Dad's beak is shorter than mums and has a dark tip.

Jono (eaglecam FB Admin) has followed Sea Eagles in the area for several years. Here is his take on the differences..(also has a great Flickr site with lots of pics)

"The male bird is slimmer in appearance, has a thinner neck and a smaller head. His head shape is quite distinct from the female's; he has a much rounder crown. His behaviour on the nest is different also - he is much more attentive to his surroundings than the female. The female is more likely to arrange a few sticks on the nest when she is sitting whereas the male is constantly looking around into the forest. The female has a larger patch of dappled white on her shoulders and has more feathers on her legs."
