I was fortunate to visit the NWP several times through the 1970's into the early 1980's . I remember the small group of Alpine ibex in their paddock at the far end ; wolverines in an open enclosure which would probably now be considered far too small ; the large open-top Lynx enclosure with its raised viewing platform , very innovative then ; the Iberian wolf in their wooded enclosure . The walk-through aviary held a collection of small passerines which bred well with surplus young being released .
I have three Guide books dated 1972 , an updated version form 1977 and a larger new one from the 1980's . All give a lot of information and detailed maps . The Pheasant Trust was founded in 1960 and a good number of species were exhibited , though they had gone by the time of the later Guide book . Species listed for the Tropical Pheasant pens - Malay great argus , Siamese fireback , Sonnerat's junglefowl , Palawan peacock pheasant , greater Bornean crested fireback , Bornean great argus , grey peacock pheasant , white-eared pheasant .
A list of notable breedings is in the later book - wheatear 1965 , stone curlew 1969 , common scops owl 1973 , roe deer 1976 , Cabot's tragopan 1976 , mountain hare 1981 , ringed plover 1982 , Iberian wolf 1983 . There was also a couple of Asian golden cats in the late 1970's .
Some species mentioned as being in the Park - European suslik , booted eagle , beech marten , a Nocturnal house with genets , porcupines , mongooses , hedgehogs , weasels , small rodents .
