Perhaps the Argyll Wildlife Park near Inveraray. Founded by a protegee of Sir Peter Scott, on my visits in the 80s it had a superb collection of wildfowl (including every subspecies of Canada Goose) plus free ranging Red Necked Wallabies and Soay Sheep and Mouflon and a nice collection of pheasants and cranes and of native and introduced Scottish taxa. When I visited again in the mid-90s it had changed hands and was owned by a former Clydeside shipyard joiner who had allowed the place to seriously decline. There were lovebirds in household birdcages next to the till in the ticket office, the waterfowl were nearly all domestic, and the enclosures were falling to bits. Ten years later I drove past the site and everything was gone bar a few derelict enclosures.
