A stacked bar chart with date increasing along the horizontal axis from 05/22 to 06/13 and the total number of mantling events increasing along the vertical axis from 0 to 12. There are three different colored bars representing different time periods of the day: morning, midday, and evening. There is a max in mantling events (12) on 06/08 and 06/13.

Reading the Graph: When do nestlings mantle their prey the most? The least? Is there variation day to day? How does the number of mantling events change as the days advance and the nestlings get older? Find out and see if you notice any other patterns by simplifying the graph with the interactive feature. Look for the checked boxes under “Choose What to Display,” to toggle on and off the different choices.

Notes: There are no mantling events before 05/27 because we did not have a button to collect that data until that day. For each day, the height of the bars refers to the total number of mantling events for that day during daylight hours (5:00 A.M. – 9:00 P.M.). The different colors refer to time periods during the day (morning = 5:00 A.M. – 10:00 A.M., midday = 10:00 A.M. – 4:00 P.M., evening = 4:00 P.M. – 9:00 P.M.). Also, keep in mind that some days and periods of the day were better covered by participants than others.
