BIG DAY LESSONS: A Chicagoland birder recounts 11 lessons learned while doing three years of monthly Big Days

摘要

Every month from January 2013 to January 2016,1 did Big Days in Lake County, Illinois, where I live. I missed only three months out of those 36, so I was able to put together 33 monthly Big Days in a three-year period.I've slowed down for various reasons since then, but I still do Big Days off and on in some form or another, and I probably will until I can't. I just like doing them.
