It takes energy

The Robins are feeding young.

Both parents are gathering worms.
The recent rains make their job easier.

The male Eastern Tail-blue Butterfly

sips a dew drop from the tip of a blade of grass.
He will find nourishment from the Hen bit as well.

The Bumble Bees are feeding in the Azaleas.
More bees have come now that more flowers are in bloom.

The Yellow-rumped Warblers are still in the area.
They migrate for nesting.
He is in his summer colors.
Perhaps he finished his molt before heading north.
