Does the chance of smaller species visiting the feeding station change day to day?
Reading the Graph: Did the chance that a species arrive at the feeder during a half-hour time interval change day to day? How do species compare? 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 species.
Notes: Each day is split into 30-minute intervals from 5:00 to 21:00 (i.e. 9:00 pm), and the height of each bar is the percentage chance that a species will arrive during each of those time intervals that was watched for at least 15 minutes. Each color refers to one of the four smaller focal species. The four larger focal species (Blue Jay, Northern Cardinal, Red-bellied Woodpecker, Red-winged Blackbird) are featured in another graph. Be careful comparing different graphs because the values on the vertical axis will change.
