ML,
The boss is really the expert. I think she is half bird at heart....and I luv it...er, her. The little that I know, I glean from her and reading the Purple Martin Forum
PM Forum . When we went thru our apparent loss last year, I studied up a little and the standard plan is that they often leave the nest and don't come back until next year. It is also possible that they will return a few times over the next few days after first leaving, but ultimately take off for the balance of the year.
