I came across this post by John Trapp at Birds Etcetera where he describes a Michigan listserv post on the location of a Saw Whet Owl. I've asked John to share his thoughts on this practice as many of the comments on my hoo in taboo post as well as the poll post seem to indicate that this is not common practice amongst birders. I'd love to hear from folks that live in areas where locations of owls are readily revealed on list servs to see what their thoughts are. Hopefully John and others will respond.
Have a great weekend and Happy Easter!
