@Summer Tanager, the bird certainly helps make the beautiful part! Pratincoles are just wonderful. I had only seen a wild individual far away a few years ago, and this was the first time I got to enjoy them close-up.
I have never seen a live pratincole (I live in the U.S.), but a friend who visited the Pinola Aviary in Louisiana last year showed me some photos of their colony of Collared Praticoles that I assumed were imported from a European Zoo a few years ago. They look like incredible birds - sort of a mix between a tern and a swallow!
