This stuffed tawny owl (Strix aluco) is fitted with a permanent leg ring, which allows the specimen’s legal provenance and identity to be verified. The accompanying CITES documentation confirms that the specimen complies with the applicable laws and regulations regarding protected species and trade in them. Thanks to the combination of the fixed ring and official paperwork, the origin is transparent and verifiable, which is important for collectors, educational institutions and decorative applications where compliance with nature conservation legislation is required.
