I remember when we would drive down an old dirt road in the mountains bluebirds would fly ahead of us.
They would then stop on a fence post as though they were waiting for us to catch up with them and then as
we got near to them they'd take off and fly ahead of us and repeat the same pattern.
I always thought they were so happy to have visitors that they were escorting us down the road. Last week when we went to the mountains I was so pleased to find that they've installed nesting boxes occasionally down the fence line along the road. They seemed to perch near or on top of the boxes...........
