Flaco's remains, including wings and tissue samples, were transferred to the American Museum of Natural History to become part of its scientific collection.
While the remains won't be on public view, they will be used by scientists and artists to make educational materials that may be seen in the future.
Flaco was freed from his cage at the Central Park Zoo in early 2023 by a vandal who breached a waist-high fence and cut a hole through a steel mesh cage. The owl had arrived at the zoo as a fledgling 13 years earlier.
Zoo officials and his fans were at first worried about his survival, but he soon proved adept at catching rats and other prey. The zoo later suspended efforts to recapture him after failed attempts.
Flaco died after eating pigeons infected with virus and was exposed to rat poison before flying into an Upper West Side building on Feb. 23.
Flaco's death was a heartbreaking end for the birders who documented his daily movements and the legions of admirers who followed along, as people posted photos and videos of the majestic owl with a nearly 6-foot wingspan perched on tree branches, fence posts, fire escapes and water towers - as well as his hours of hooting.
Since then, Councilmember Shaun Abreu introduced the first of three pieces of Flaco's Laws to stem unnecessary bird deaths.
