Black-necked Stork

I imagine the species I lack which there is the best chance of seeing in the next few years is Milky Stork, as these are about in low numbers throughout European collections. Had the last individual at Vogelpark Niendorf not died shortly before my visit, I'd have it already Suspect my odds of seeing the other three are significantly lower unless I leave Europe, as none are around anymore and I don't see much chance of any new stock being imported.

Asian Open-billed are absent from public collections in Europe now, too, although I believe they are still around in private collections - I'd love some to pop up somewhere I could visit, as I didn't get a record shot when I saw this species at Blackbrook Zoo.

you could count them if you want. The Singapore Painted Storks all come from the free-flying colony at the zoo, and the Malaysian ones from the free-flying colonies at several zoos, primarily Zoo Negara in Kuala Lumpur. They have spread out from those colonies but I don't feel comfortable counting them on my list. The Milky Storks seen here and there in Singapore likewise come from the zoo. There was a proper Millky Stork reintroduction attempt at Kuala Selangor in Malaysia, and I saw them there in the early stages but didn't count them because they were just a handful of released birds - the reintroduction never really took hold and there's only a few of those same birds left there now.
