The park takes its name from the 369 metres (1,211 ft) peak, Golden Hill or Kam Shan (金山), which is the highest feature in the area.
Kam Shan, or Monkey Hill to most locals, is a famous macaques kingdom in Hong Kong.
Other birds found in the park include the black-eared kite (Milvus migrans lineatus), house swift (Apus (affinis) nipalensis), greater coucal (Centropus s.sinensis), common kingfisher (Alcedo atthis), rufous-backed shrike (Lanius schach) and common tailorbird (Orthotomus sutorius).
Melastoma species, rose myrtle (Rhodomyrtus tomentosa), acronychia (Acronychia pedunculata), Hong Kong gordonia (Gordonia axillaris), fragrant litsea (Litsea cubeba), red machilus (Machilus thunbergii), pop-gun seed (Bridelia tomentosa) and ivy tree (Heptapleurum heptaphyllum), and the ram-rod bamboo (Pseudosasa hindsii) are the common varieties in the Country Park.
An animal rights volunteer group was formed in 2007 when people discovered illegal hunting activities in the park.
Police arrived at the scene, Food and health chief York Chow Yat-ngok said he stepped up patrols to clear traps.
