A webcam set up in the tower at the university captured the moment when Diamond delivered what is expected to be up to three potential new chicks.

They also saw Diamond's partner Xavier return to the nest with dinner, a hapless small bird, to see their egg for the first time this week.

It was laid at 10.40am on Tuesday.

Project co-ordinator Dr Cilla Kinross said people should keep watching the webcam as more eggs were expected in the next few days.

She said the birds would not start incubating the eggs until they had several eggs.

Dr Kinross said the process, known as synchronisation, meant the chicks would be of a similar size when born which evened out their opportunities to get feed.

WATCH: BIRDS INSIDE THE TOWER NEST

"Diamond, she would be about eight, she came in 2015," she said.

Xavier, the male, arrived in 2016.

Dr Kinross said the public would again have the opportunity to select names for the chicks, probably through an online poll.

"This year I am going to be [using] Wiradjuri names," she said.

She said last year's baby, Izzi, only left the nest last month which meant he had stayed far longer than expected.

However, he needed a shove to move out.

"They blocked him from coming into the box," she said.

Dr Kinross said the scientific research project into the breeding behaviour of the falcons, which started in 2012, was coming to an end.

However, she said the webcams would continue to film the birds for educational purposes.

She said there had been two different female and three male birds in the nest since the start of the project.

And Dr Kinross said public vision of the birds was about to be boosted.

She said she had been given a camera that can be mounted outside the nest to provide a different view.

However, she is still working out the logistics of getting it installed.

The Falconcam Project has been operating for several years after a pair of peregrine falcons were spotted around CSU.

A nesting box was built on the tower and the birds quickly took to it to create a nest.

It is now watched by people around the world.
