In order to encourage birding-life balance, some folks may consider the value of taking a day off from the 20 Bird MDR as a birding shabbat. Personally, I usually take Sundays off. I still try to identify every bird I see, and I may even write them down, but I take a rest from the relentless birding drive for the daily 20.
LDS Temple in Lake Oswego, OR--nice to be able to get birds at a wedding, in this case Anna's Hummingbird, Song Sparrow, Northern Flicker, Black-capped Chickadee, Western Scrub-Jay, etc.
We all need balance. The 20 Bird MDR is a tool to help you to keep birds in your life if you tend to get caught up in other things. If you lean too far the other way, consider a birding shabbat. You can still watch birds, but you don't have to go crazy. By all means bird, but bird responsibly!
