Two eggs were laid in the first year of breeding in 2022 and one failed to hatch.
A live webcam was installed in their nest tray the following year, and curiosity in the birds and their growing family has grown ever since, the Trust said.
The webcam received more than 500,000 views last year.
Ellis added: “[As] the chicks develop and begin to move around more, they may disappear from the view of the webcam from time-to-time, but in all probability they are just exploring the rest of the nest tray.”
The Very Revd Jo Kelly-Moore, Dean of St Albans Cathedral, said: “These remarkable birds have become much-loved members of our Cathedral community, and it is a joy to see their family continue to grow year after year.”
