And this year we get a birds eye view of all the action with the webcam live and online. With the arrival of the fourth egg the incubation period begins. A familiar sight for the next 33-35 days will be Sheila, the female adult, in the next box with her four eggs tucked neatly underneath as the eggs are rarely left uncovered during this time. Last year in a Victorian first, Alcoa Anglesea installed a webcam on the nestbox, broadcasting the images of the Peregrine Falcon pair at Anglesea over the internet. After the fledgling Uno departed in December last year, the camera was switched off as the falcons dispersed to their nonbreeding territories. The webcam at www.alcoa.com/falcons is now back online for another season providing us images of day-to-day life in the Peregrine Falcon nest from the arrival of the first egg until the last fledgling departs. A quick calendar check and it looks like an expected hatching date between the 29th of September and the 1st of October. However we’re not ones to count our eggs before they hatch. Despite laying four eggs last year, only one egg successfully hatched. Whilst there is no explanation for why this happened, the presence of unhatched eggs at other nests across the state suggested the cause was wider spread and may be the consequence of drought conditions. Only time will tell whether this year proves more sucessful. There’s been plenty of action so far with almost daily updates placed on the website capturing the arrival of the pair’s four eggs. In the meantime, stay tuned to the website for further exciting developments and observe the goings on from the safety of your office computer.

Lee, your job seems to take you up onto the floors of the Power Station a bit, what are you doing up there? The electrical group has equipment to service and maintain on all floors of the power station. Air blowers, oil burners, lighting, water cannons, thermocouples & critical valve controls, to name a few. We hear you have had some interesting encounters with the site’ s Per egrine Falcons in the few years. site’s Peregrine What’ s gone on? Recently after responding to a breakdown What’s on the 7th floor hoist I decided to use the stairs instead of the elevator (for personal fitness reasons). As I was accessing the first step my feathered friend decided on a very swift territorial swoop, this took me by surprise. Similar happened last season whist repairing lights on the 5th floor. Do you have any advice for others? These birds move at very high speeds and because of plant background noise, hearing protection PPE and plant structure they can easily surprise. If your work takes you to the upper levels of the boiler keep a keen eye out for the the falcons as I’m sure that they keep a close check on us. Three point contact whilst accessing stairs is very important. Keep tools and materials in a managed fashion that reduces any risk of them falling down the structure. ...LEE SLAVEN
