Jackie, a beloved bald eagle and livestream star, dies of mysterious illness

Thousands mourn the death of the eagle at California's Big Bear Lake, whose life was closely followed via livestream

Jackie - the beloved bald eagle at California's Big Bear Lake whose livestream was followed by millions of viewers as she birthed and raised chicks - died on Monday due to a mysterious illness. She was 14.

Jackie had been receiving treatment at the Ojai Raptor Center since mid-July when she was found weak and unable to fly after a scuffle with two younger eagles. Experts at the center had discovered that she was suffering from severe anemia, and suspected she had been sick for weeks before the fight grounded her.
