The researches on activity rhythm and behavioral time budgets of vulnerable or endangered species were of great importance to form the effective conservation strategies, Reeves忆s Pheasant (Syrmaticus reevesii) was a vulnerable species endemic to China, whereas little information on activity rhythm and behavioral time budgets of this species was available. Therefore, we used infrared camera technology, from March 2012 to March 2013, to survey the activity rhythm and behavioral time budgets of wild Reeves忆s Pheasant (Syrmaticus reevesii) in Caihe Town, Guangshui City, Hubei province. We radio tracked and outlined 8 Reeves忆 s Pheasants in the study area at first, and then we determined 4-5 sites as candidate camera sites in each home range. We selected two camera sites with a distance apart from at least 200 m in a home range synchronously, and irregularly moved these cameras across the candidate camera sites in this home range. In consequence, we set 16 infrared cameras at 40 candidate camera sites. The daily work time of a camera was set from 4:00 to 22:00 with the reference to some previous reports on this pheasant behavior, and we defined it as a camera day. We also divided the behavior of wild Reeves忆s Pheasant into seven types, including feeding, moving, grooming, vigilance, resting, conflicting, and raising According to the available information on pheasant behavior. As a result, the total work time of these cameras in the field added up to 1774 d. We obtained totally 2242 videos in relation to Reeves忆s Pheasants that were
