Gray-headed Chachalaca

Choose What to Display

A clustered bar chart to explore if food being put out on the feeder influences the arrival of the Gray-headed Chacalaca. There are three different bar colors referring to the morning, midday, and night. The horizontal axis is the time since food is put out and the units are in 5-minute intervals up to 60 minutes (for example, 0-5, is the interval from when food is put out to 5 minute after). The height of each bar is the percent chance that a Gray-headed Chacalaca will arrive during that time interval. There doesn't seem to be a pattern in the morning, but the percent chance of survival decreases as the minute interval increases from the time food is put out in the evening and midday.

Reading the Graph: Does food being put out on the feeder influence when Gray-headed Chachalaca arrive? In the morning? As the sun sets? Find out and see if you notice any patterns by simplifying the graph with the interactive feature. Look for the checked boxes under “Choose What to Display,” and toggle on and off the different periods of time: morning, midday, and evening.

Notes: The time since food is put out is split into 5 minute intervals up until 60 minutes with zero referring to the time when food is put out. When you see 0-5, it refers to the time period 0-5 minutes since food is put out. Each color refers to one of the three time periods. Morning refers to 6:00 am – 10:00 am, midday to 10:00 am – 2:00 pm, and evening to 2:00 pm – 7:00 pm. Be careful comparing different graphs because the values on the vertical axis will change.
