Bird Nerd’s Guide to Spring Arrivals in Eastern Ontario

Using eBird’s Explore Data — Bar Charts, I created graphs highlighting each species’ frequency of observations. eBird describes “Frequency” as the percentage of checklists that report a species within a specified date range and region. It is the most common way of displaying the eBird data and provides a good idea of relative occurrence and seasonal timing.  The parameters I chose, are Eastern Ontario counties (all), with a time frame of 1990 – 2017. Take note of the numbers displayed on the Y-axis; they are the frequency displayed in percent. Birders can develop a sense of what is common, uncommon, rare and even very rare by looking at frequency scores. For example, Yellow Warblers have some of the highest frequency scores. Alternatively, very rare finds such as Yellow and King rails have some of the lowest. Anyhow, I hope that birders of all skill sets get either a refresher or a lesson on the migration timing of specific species, especially their most sought-after species! Without further adieu, I cut right to the chase below.

Good Birding 🙂
