I know you’re an experienced bluebirder, so I apologize for asking this, but did you have a sparrow spooker up? Not sure if you had eggs yet? Just trying to learn more myself. It’s got to be more difficult staying on top of these things when you have a trail.
I know that you must be really nervous for that new pair. Glad they’re there, but wish you could’ve trapped those HOSP. Praying that it all works out!
