NatureCounts - Ontario Breeding Bird Atlas

Seasonal bar charts

The following table provides a seasonal bar chart of species occurrence based on data associated with this project only. The thickness of the bar for each week is based on the frequency of reports based on all data selected (e.g. 25% of all daily observations). To view more advanced options as well as data from other projects, you can go to the NatureCounts data summary page.

You can restrict the bar charts to only some of the datasets that are part of this project
