Blackbirds again.

This is not precisely where I am living/sleeping,
but several miles up the road in a commercial strip
where I get fuel for the car and fast food for myself.
That stretch of road borders a wetland/marsh.

Young blackbirds, whom I cannot see, are clearly, loudly heard
practicing their whistling.
Goodness, it's piercingly clear in the sunny air.
Making of summer memories for me.
