According to Zootierliste London Zoo is apparently also the only UK holder of the Asian woolly-necked stork (Ciconia episcopus episcopus).
It is also the only one with white woodpecker and I believe the only public collection in the UK with any woodpecker species.
Also a new arrival being pink-necked green pigeons. Unsure if these are on public display anywhere else
There are alot of birds of prey only held at one public collection in the UK (onshow) Hayle is also the only holder of yellow-faced siskin and I'm sure there's a few odd birds at lotherton just cant think of them off the top of my head.
They have the only Peruvian Thick-knee, then possibly a couple of other unique species; they also have a few very uncommon species such as, Spix's Guan, Erckel's Francolin and Yellow-knobbed Currasow; amongst a lot of other uncommon species.
Wow! That is a species I have wanted to see for a very long time. Trip to Paignton already in planning.....
Three species seen at Birdland last Friday - Indian francolin ( Francolinus pondicerianus ) - according to ZTL the only others at Sharjah Northern carmine bee-eater ( Merops nubicus ) - only 1 left now and according to ZTL this is the only bee-eater of any species on display in the UK . Desert finch ( Rhodospiza obsoleta ) - I only saw one in the Desert House , though there could be more .
What about the tinamou at Paignton, not only a unique species but it's the only tinamou of any species in the UK!
