BLUE (bird in the ) GRASS

At first, she seemed too small, almost unnoticeable.
Blue from a distance, but probably
a sunsetting trick of the light.
Then gone in a streak.
But she returned, blue as blue can be.
An Indigo bunting. True blue in summer
We hoped, just a scout, and soon
the rest of the flock would appear.
We waited, and the sun set, the
mosquitos came out. We went home.
Maybe another day, soon, dozens of them at once?
