The bivariate plots of distances traveled to collect chickens and the number of chickens collected are shown in Fig. 5.
These plots show that TSs and HTs collected approximately 41.5 chickens each time during the Chinese New Year festival
(95 % CI=18.8–54.4) and only 20.0 (95 % CI=15.4–25.6) and 15.3 chickens (95 % CI=15.0–15.6) during the Hungry
Ghost Festival and normal periods, respectively. The average distance traveled to collect chickens was 4.4 km (95 % CI=
4.2–4.5) in all periods. The mean number of chickens collected by TTs each time was 62.7 chickens during the Chinese
New Year (95 % CI=22.6–95.3), 26.2 chickens during the Hungry Ghost Festival (95 % CI=19.7–36.8), and 19.4
chickens during normal periods (95 % CI=18.5–20.2). Distance traveled to HTs’ locations ranged from 24.9 to 25.2 km
(95 % CI=24.2–25.9).
