Situations During Vocalizations

Choose What to Display

This is a stacked bar chart with two categories on the x-axis: nestlings vocalizing and adults vocalizing. The y-axis is the percentage of clips in which a situation (ex: brooding) was recorded for each of the categories on the x-axis. The graph helps us answer the question that is the title: What's happening when hawks vocalize? Of the 1,109 clips with nestlings vocalizing, 30% had brooding and about 42% had feeding of nestlings. Of the 25 clips with adults vocalizing, 60% has brooding and about 16% had arrivals or departures. These were the highest percentages of clips.

Reading the Graph: What’s happening when the nestlings are vocalizing? How about the adults? Compare nestlings and adults, and then look for the check boxes under “Choose What to Display,” and toggle on and off the different data sets to see if you notice any other patterns. Each color refers to what behavior is occurring in the clip when either nestlings or adults are vocalizing. (N=the number of clips with vocalizations)

Notes: For simplicity, we’ve combined some categories of date collected by participants. “Feeding Nestlings” includes instances when adults were feeding nestlings or eating prey because the adults sometimes ate while feeding nestlings. We have not shown data for “Prey Transfer” because no such events were recorded. “Unsure” refers to clips with situations that weren’t clear (participants didn’t agree on what occurred).
