So you're standing beneath a flowering tree, all but gawking at the profusion of blossoms.
Then you see it, up high. A nest.
You look hard, to make sure. But there can be no mistaking it.
Is it active or a holdover?
You can't hear anything. There are no comings or goings. Not at that moment anyway.
You can look again later. You will look again later.
For the moment, all you can do is wish them luck. If they're there.
If anyone is home.
