Walter Returned

Jim, reported the sighting of a great white egret on Ivy Lake the other day and speculated that it might be “Walter” our regularly returning bird. This bird was ringed in 2003 in France and first arrived at Blashford in August of that year, since then he has come back to spend each autumn and winter with us. We know that it is the same bird each year as he was ringed as a nestling with a combination of coloured rings. He is now 15 years and 3 months old, a good age for almost any bird. I have seen a maximum age for this species in Europe of 17 years, but it seems the official European bird ringing site (EURING) reports a maximum age of only 13 year and 9 months, which would make Walter Europe’s oldest great white egret by some margin.

With this in mind I was very keen to establish if the bird seen was actually Walter and not some other visitor and as I locked up yesterday there he was outside Ivy North hide, with rings on full show. This egret was indeed Walter returned and apparently a record breaker.

Of course he would have also been Europe’s oldest last year as well, he was reported then and does not seem to have made it onto the database, so perhaps there are others, even older out there that have also not got into the records yet. But, for now at least we will claim him as the oldest.

So how old might he get? The oldest great white egret (also known as “Great egret”), I can find is 22 years in North America and a grey heron has reached 37 years 6 months, so we could be seeing him for some years yet with a bit of luck.
