A stacked bar chart where the height of each bar is the total number of prey deliveries within each hour of the day. The three different colors used refer to the week 1, 2, and 3 during data collection. Regardless of which week it is, there seems to be one peak early morning and another peak mid-afternoon in the number of prey deliveries.

Notes: For each hour of the day, the height of the bars refers to the total number of prey deliveries for that hour. The different colors refer to the three weeks of data collection (week 1 = 05/21 – 05/28, week 2 = 05/29 – 06/05, week 3 = 06/06 – 06/13). Also, keep in mind that some hours of the day and weeks were better covered by participants than others.
