Thanks for sharing this, Greg!
There are a few threads on the iNat Forum about Flaco:
- https://forum.inaturalist.org/t/eurasian-eagle-owl-in-central-park/
- https://forum.inaturalist.org/t/passing-of-flaco-the-owl/
As well as a Wikipedia article, at least four books, and many observations of Flaco on iNaturalist.
