ABSTRACT
In order to understand the background of the field breeding ecology of Reeves's pheasant (Syrmaticus reevesii) inside and outside of protected area, an investigation on nest predation rate, potential nest predators and the habitat factors affecting nest predation was conducted at Dongzhai National Nature Reserve, Henan Province and Pingjingguan Village, Hubei Province, which were protected and non-protected area, respectively. The fieldwork was conducted from March to July 2014, and artificial nests (taking eggs as bait), camera traps and habitat plots were used at these two sites to catch information about nest predation. Experiments were designed in two rounds, including the early-breeding stage (March to April) and mid-breeding stage (May to June). We placed 149 artificial ground nests with 62 randomly picked nest sites, each monitored by one camera. The working days of all cameras were 1315 days, and we finally obtained 7776 pictures and 6950 video clips. The results showed that the rate of nest predation outside the protected areas (Pingjingguan) was higher than that in nature reserve (Dongzhai), with highly significant diffe-rences both in early-breeding and mid-breeding stages. In two stages, more nest predator species (11 and 6 species in two stages, respectively) occurred in Pingjingguan than in Dongzhai (7 and 5 species, respectively). In Pingjingguan, Glires and Corvidae were top predators, while in Dongzhai Raccoon dog (Nyctereutes procyonoides) was firstly ranked. Slope degree and arbor canopy cover were positively related with the nest predation rate in Pingjingguan, while fallen leaves coverage had significant influence on nest predation in Dongzhai. We also found wild Reeves's pheasant paid visits to 13 artificial nests for 18 times by viewing the pictures and video clips.
