Perhaps. That'd be the other option. I know there's just one and it live(d) up in the top aviaries, beyond the African walkthrough on the left hand side.
I have Lotherton photos if anyone wants to see:-

I find it weird how many people think Lotherton is a good set up- its certainly not bad- particularly as it's free and some of the birds kept there are unusual. Its a good collection, but I can't help but think that they are not displayed as well as they ought to be. I find the aviaries a little tired and shabby, and many of the waterfowl are kept as 1.0.0 or 0.1.0. I think it was much better when I used to visit as a young child- its a shame.
I remember they used to have quite an ambitious 'masterplan' (if you can call it that). There was a plan to divide the park up into zoogeographic regions- the current condor aviary and rhea paddock would see the basis of the Neotropical section, the Oceania part would be the newer top aviaries, (where the black/trumpeter hornbill and seriemas are), The African aviary and ground hornbill paddock would be the African section, and I seem to think the middle area with the ponds and little paddocks would be Eurasia. So little of this plan has been implemented since the construction of the big aviary, no doubt due to a lack of cash.
I have to say though, their condor aviary is excellent, its very naturalistic and quite roomy. If the whole bird garden was finished to this standard I think the park would top notch.
