A Comparison of Bird Biodiversity

Winter vs. Spring

This interactive data visualization shows the different types of birds that were observed in the winter and spring of 2016 in Canada, organized by taxonomic classification (eBird Observation Datasets obtained from Global Biodiversity Information Facility, published by Cornell Lab of Ornithology). The sunburst diagram on the left shows the species composition of the 312,866 birds that were reported to be seen in Feb 2016; the sunburst diagram on the right shows the species composition of the 1,419,107 birds that were reported to be seen in May 2016.

Use the mouse cursor to hover over a segment of the sunburst diagram to highlight and display the name of the bird order/family/genus/species as well as the corresponding percentages for both months. Move the mouse cursor off the sunburst diagram to unhighlight the bird order/family/genus/species.
