Abstract The hunting behavior, snail size selection, and time-activity patterns of non-breeding Snail Kites (Rostrhamus sociabilis sociabilis) were studied in Guyana rice fields. Kites spent 62% of the photoperiod perching, 19% foraging, 13% in maintenance activities, and 6% flying. As the day progressed, the percentage of daylight hours spent perching increased significantly, while foraging decreased significantly. Kites successfully captured and ingested Pomacea snails in 78% of the foraging bouts observed. The mode of hunting was evenly split between coursing (50.7%) and still-hunting (49.3%). Searching and returning times were related to time of day, as significantly more coursing hunts and still-hunts occurred in mornings and late afternoons, respectively. Prey handling time was the most time-consuming component of a foraging bout. Time spent searching for prey, returning, or handling prey was not related to snail size. The size distribution of captured snails differed significantly from that of available snails; kites selected more medium snails and fewer small snails and took large snails in equal frequency to that at which large snails were available. Kites captured the same-sized snails when coursing as when still-hunting. As rice grew, kite utilization of rice fields declined, and the frequency of still-hunting decreased while course-hunting attempts increased. The daily caloric intake of kites was estimated to be 104.2 kcal, the daily energy expenditure 85.7 kcal. Results are discussed in relation to consumer choices of specialists. The most important decision a foraging Snail Kite may make is what patch to search in and how long to search before abandoning patches.

Purpose:Exercise leads to a lower risk of coronary artery disease (CAD). However, whether time of day physical exercise has effects on CAD is still unclear. The present study is to investigate the relationship between time of day physical exercise and angiography determined CAD in a Chinese population.Subjects:A total of 1,129 consecutive participants who underwent coronary angiography for the first time were enrolled in our study. Participants were divided into non-CAD group and CAD group according to the result of coronary angiography. We used a predesigned questionnaire—the work-related activity, leisure-time activity, and physical exercise information were recorded in the form of self-reporting.Results:Doing physical exercise was associated with a reduced risk of CAD, after adjusting the established and potential confounders, with an adjusted odds ratio (OR) of 0.48 (95% CI, 0.35–0.67) compared with those who did not any physical exercise. Moreover, the risk of CAD could linearly decrease with increase of intensity, duration and frequency of exercise. Further stratification analysis revealed that the protective effects of exercise were more significant in the afternoon and evening group than in the morning and forenoon group. The adjusted ORs of doing physical exercise in morning, forenoon, afternoon, and evening groups were 0.53 (0.36–0.78), 0.51(0.27–0.96), 0.46(0.25–0.85), 0.43(0.28–0.66), respectively, compared with nonexerciser (p < .05).Conclusions:Doing physical exercise can decrease the risk of CAD, and exercising in the afternoon or evening may have more significant effects on the prevention of CAD than in other time of day.
