Now that the chicks are five weeks old, it won’t be long before they are fitted with their leg rings! We ring all of the osprey chicks that hatch at Rutland, each with two rings – a metal BTO ring and a coloured plastic ring with a distinct number/letter combination. Rings are a great way of identifying our birds, discerning where they hatched from and in what year, and providing information on their whereabouts, if someone spots one elsewhere and is able to read the ring. It helps to indicate how successful the project is, from the number of Rutland-fledged ospreys that are returning to the area and breeding.
It’s also nice to see that Rutland ospreys are venturing further afield and have helped the osprey population to spread into other areas of the UK. For example, from ring numbers we know that one of our translocated males, 11(98), went to North Wales and bred there for ten years, raising 27 chicks. Also, both females that have bred at the Dyfi Osprey Project were/are Rutland-fledged birds. The current female, 12(10)/Glesni, is the grand-daughter of the infamous 03(97) or “Mr Rutland” as he was known to some – the very first translocated osprey to breed at Rutland Water, who bred for 14 years and raised 32 chicks. Click here for more information about 03.
This year has brought about some special news regarding 03(97). One of Glesni’s chicks from 2013, 2R/Clarach, is breeding for the first time this year with an unringed male at Aberfoyle in Scotland, and is currently raising two chicks! This is fantastic news for Dyfi, Aberfoyle and also Rutland, as Clarach is the first great-grandchild of 03’s to breed, and therefore her chicks are 03’s first ever great-great-grandchicks!
Clarach isn’t the only great-grandchild of 03’s to return to the UK, as Rutland-born male 4K(13) returned to Rutland in 2015 (click here to read more). However, 4K is yet to breed. Clarach visited Rutland in April this year before heading north, and we would have loved her to stay here, but it doesn’t matter where she breeds, we are happy that she is and has brought the fifth generation of 03(97) into the world!
