Identification help

This was taken last summer. I\'d be grateful if anyone more ornithologically savvy than me could help with ID. Thanks!

Slender-billed conure, South American species found in Chile.

I first saw them at Chester in 1978 (unlabelled) and it took me several weeks to find out what they were.

Thanks!

It's not listed on Zootierliste, which threw me. The collection at Paulton's Park is rather overshadowed by the theme park (a very nice theme park, aimed at younger children, but a theme park nonetheless), but it has some very nice species. Including this one!
