When do larger species visit the feeding station?

Choose What To Display

A bar chart with four different colored bars that each refer to a species: yellow-green is Blue Jay, dark green is Northern Cardinal, orange is Red-bellied Woodpecker, and light blue is Red-winged Blackbird. The horizontal axis is half-hour time interval from 5:00 to 20:00 and the vertical axis is percent chance that a species arrive from 0 to 100. The Blue Jay has it's highest percent chance of arrival from 6:00-9:30 at 90-100% and then decreases steadily until it reaches 0% at 18:30. The Northern Cardinal fluctuates from 70% to 100% throughout the day from 5:00 to 18:30 and then drops off to 44.44% at 19:00 and then 0% for 19:30 and 20:00. The Red-bellied Woodpecker increases from 7.69% at 5:30 to 57.14% at 6:00. Then it fluctuates from just above 50% to 90% from 6:30 to 18:00 before dropping to less than 10% at 18:30 and then 0%. The Red-winged Blackbird is at 100% for most of the day, from 6:00 to 16:30, and then 92% 17:00 to 18:00.

Reading the Graph: When do species arrive at the feeder? In the morning? As the sun sets? 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 20:30 (i.e. 8:30 PM), and the height of each bar is the percentage chance that a species will arrive during each of those time intervals. Each color refers to one of the four larger focal species. The four smaller focal species (American Goldfinch, Black-capped Chickadee, Tufted Titmouse, White-breasted Nuthatch) are featured in another graph. Be careful comparing different graphs because the values on the vertical axis will change.
