Oh how funny is that. That's exactly how we do it here. Got binoculars stationed at the best windows as well.
No need to go outside. I don't have to worry about scaring any away.
That's not how it is supposed to work? But it works great!
LOL! I can do that here too during migration seasons, but the rest of the year it’s slim pickings.
But I was thinking of turning a dial knob late at night hoping for a rare signal as being like walking a woods or field hoping for that rare bird. For me, there is something satisfying in the effort involved. If I hear that rare signal or see that rare bird, I have earned it.
