The last known location of the Heulwen blue buzzard is near Ruabon Mountain, Wrexham, on August 29.

The number of blue buzzards has been recovering since the 1950s. There are 35 pairs of birds in Wales.

Dr Cathleen Thomas of the Royal Society for Bird Protection (RSPB) said: 'Only a few weeks ago, we were celebrating the success of being a bird breeder throughout the UK, but these young birds are disappearing. in suspicious situations when only a few months old. We, who are involved in observing and protecting these young birds, are very sad, and it is a serious problem with an endangered species that continues to decline. '

Although she said it was unclear what happened to Heulwen, one of the main factors limiting the number of blue urchins as ' illegal killing' is related to the strict management of chicken hunting grounds. wood.

Heulwen was tagged at a bird nest in Gwynedd as part of an EU-funded project, before flying over Snowdonia toward Wrexham.
