MEXICO CITY (AP) — They call him “El Jefe.” He is at least 12 years old, and his crossing of the heavily guarded U.S.-Mexico border has sparked celebrations on both sides. A coalition of conservation groups says “El Jefe” — or “The Boss” — is one of the oldest jaguars on record along the frontier and one of few known to have crossed a border partly lined by a wall and other infrastructure to stop traffickers and migrants. That assessment is based on photographs taken over the years. Jaguars can be identified by their spots, which serve as a kind of unique fingerprint.
