Sadly it appears that this season at least one of the eggs is not going to hatch. We are now beyond the accepted incubation time-frame for Egg-1. At this point there is still a slim hope for Egg-2.
This year there was very limited delayed incubation of the first egg which should have seen it hatch even earlier than the expected hatch date (based on previous years - graph below). In 2011 mum WBSE stayed off the eggs for nearly 12 hours on the first night, we didn't have night vision last year so we are unsure of what she did. Possibly similar given the hatch time?
2010 - egg 1 hatch 38 days 2010 - egg 2 hatch 38 days 2011 - egg 1 hatch 41 days (it was the 41st day being the morning, but actually 40.5 days if you count the hours) 2011 - egg 2 hatch 39 days 2012 - egg 1 hatch 41 days (it was the 41st day being the morning, but actually 40.5 days if you count the hours) 2012 - egg 2 hatch 40 days
2013 - egg 1 is now in 45th day 2013 - egg 2 is now in 42nd day
What to do? First and foremost, this is a research project. The primary objective being the monitoring of this breeding pair, following the death of the previous pair in 2004, and the long-term effects of the environment on their health and breeding cycle .
What is happening does add an unexpected dimension to that research. If both eggs fail to hatch we would need to apply for permission to retrieve them. The most important consideration here is the parents and when the appropriate timeframe to do this is. Embryo testing for various toxins can be a very expensive exercise as each toxin has to be tested for separately.
In summary, we are keeping our fingers crossed for Egg2 and will post another update in a few days. Thank you everyone for your support at this time.
Permission has been granted by the National Parks and Wildlife and their colleagues at the Sydney Olympic Park Authority to collect the unhatched eggs from the Sea-eagle nest for testing. They hope to find out why they did not hatch. They plan to do that on September 2, 2013

I've never seen one of those in its natural habitat!! That certainly makes me smile.
