Does the chance of less common species arriving at the feeder change day to day?

The clustered bar chart has three colors each referring to the three species that are the least common out of the six focal species: Gray-cowled Wood-Rail, Gray-headed Chachalaca, and the Rufous Motmot. The horizontal axis is the date from February 11 to February 24. The height of the bars varies from 0 to 100 percent chance that the species will arrive during one of the half-hour intervals from 6:00 am to 6:00 pm each day. The Gray-cowled Wood-Rail's percent chance of arrival peaks on 02/17. The Gray-headed Chacalaca's percent chance of arrival also peaks on 02/17. The Rufous Motmot has a low percent chance of arrival each day, ranging from zero to twenty-five percent.

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 other 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 choices to see if you notice any patterns.

Notes: Each day is split into 30-minute intervals from 6:30 to 18:30 (i.e. 6:30 pm), and the height of each bar is the percentage chance that a species will arrive during any of those intervals. Each color refers to one of the three less common species. The three more common focal species (Clay-colored Thrush, Crimson-backed Tanager, Thick-billed Euphonia) are featured in another graph. Be careful comparing different graphs because the values on the vertical axis will change.
