Golden Pheasant (Chrysolophus pictus) and Satyr Tragopan (Tragopan temmminckii) are two protected pheasant spieces (class Ⅱ) in China. As two sympatric species, the degree of their niche overlap and competition is still unclear. From July 2012 to November 2014, we set 52 infrared camera traps on 9 line transects (Fig. 1) to study the flock situation, daily activity pattern, seasonal activity rhythm and the optimal temperature selection of these two pheasants in Foping Nature Reserve, Shaanxi Province. The results show: (1) The flock behaviour of the two pheasant occurred mainly in winter, starting from late August and ending in next March or April (Table 1). (2) The two pheasant had similar daily activity patterns with two peaks in the morning and evening, however, with obvious differentiation in time niche. Golden Pheasant had one activity peak at 7:00 in the morning and another peak at 17:00. Satyr Tragopan had two activity peaks at 6:00 and 9:00 in the morning, and one peak at 18:00 in the evening (Fig. 2). (3) By analyzing seasonal activity patterns of these two pheasant, we found that both of them were most active in spring (March to May), while followed by autumn (September to November), summer (June to August) and winter (December to February) (Fig. 3). (4) The favourite temperature of the activities of the two pheasant were close to the average temperature in this month, with the activity temperature range of Golden Pheasant from ﹣4℃ to 19℃, whereas Satyr Tragopan from ﹣1℃ to 22℃ (Fig. 4). Their activity temperatures were normally higher than the average temperature of the fall and winter, however, slightly lower than the average temperature in the summer. The divergence of their activity peak periods might help these two sympatric species to aviod niche overlap, but we did not see obvious temperature adaptive differentiation between these two pheasant.
