The bar graphs from A Birder's Guide to Washington reformatted for field use by Marv Breece
For years, when I’ve gone into the field, I’ve looked for an easy way to remind myself which species I was too early or late for, and which species I might most expect to find. The bar charts in Birders Guide to WA were what I had in mind, but I needed something more portable and didn’t need the entire bird list. So I created a spreadsheet for myself, first of shorebirds, then eventually of other species. I used a number code instead of bar graphs because it was more intuitive for me personally. I’ve found these one-page seasonality sheets very helpful when I’m in the field, and after sharing them informally, I was encouraged to put everything online.
Use them as you will — view the individual pages directly via the links below, or download and print out the pdfs for paper versions. The organizing principle was single-page printable groupings. Very rare species are not included, usually. For some groups, a natural break in the taxonomic order fit nicely. For others, to avoid creating dozens of separate sheets, I lumped together a number of bird groups. If you don’t see the group you are looking for, poke around a bit.
