The names for our falcon chicks were nominated by students from Anglesea Primary School. For the fourth year in a row, Peregrine Falcons have returned to Alcoa Anglesea to the nest box on top of the water tower. However, despite laying four eggs, only two have successfully hatched. Whilst there is no explanation for why this has happened, a similar scenario occurred here last year with only one of the four eggs hatching successfully. There are several reasons why an egg may not hatch - drought, adults may be incompatible or an adult may have left the eggs resulting in a drop in incubation temperature. The positive for having two chicks instead of four is the amount of food each chick receives with less sibling competition. The more food the two chicks receive, the stronger they will be, giving them a better chance of survival. This extra benefit was clearly evident when volunteers from the Victorian Peregrine Project took the travel tower to the elevated home this month to check on the chicks. Weighing in at a very healthy 905g is our female, Dash, with all the characteristics to be as formidable as her mother. More reserved and weighing in at 590g is our male, Concorde. Sheila made her presence felt during the expedition up to retrieve the chicks - the hard hats were essential PPE under the circumstances! Whilst both parents exhibited agitated behaviour Sheila didn’t hesitate on getting a close look at the bright yellow duco of our hats. The health assessment and banding of the chicks was completed and the chicks returned to the nest box as quickly as possible so that the parents could rest easy. The webcam at www.alcoa.com/falcons continues to broadcast images from the Peregrine Falcon nest box at Alcoa Anglesea over the internet. There’s been plenty of action and more to come as Dash and Concorde continue to grow, change plumage and learn to fly. Regular updates are also included on the website on highlights of the week.

Gary Gary,, we believe you witnessed the banding of the falcon chicks. What happened? It was very interesting (and noisy). The chicks were retrieved from their nest box on the water tower which did not please the adults. It was however very amusing for the onlookers seeing the handlers swooped and collected by the parents. The helmets did come in handy! The chicks were then brought to the store where the banding and data recording took place. Any ideas what the banding is about? The chicks were banded for research purposes to determine how far they disperse and so they can recognise where they came from. Any difference between the two chicks? The chicks are now adorned with their own uniquely coded jewellery, which apparently looks cool if you are a falcon. I was told that the larger of the two is the female and not surprisingly the loudest. How was the experience? It was interesting to learn that the chicks are banded at three weeks to coincide with their skeletal structure being fully developed. All in all it was a great experience to feel the down of the chicks which was incredibly soft and to appreciate the sheer strength of these powerful birds and their amazing talons. ...GARY HINDLE
