Great blue heron

What does a heron want?
fish, water,
a nice tree to live on,
some straws for a nest,
and a companion to start a family.
I saw one at a pond,
standing motionless like a pillar,
breathing, watching, waiting,
feathers quivering in wind.
I saw it uncoil its body,
and strike its head in water.
It seized a fish,
gulped it,
and on its great blue wings
took off
and away and away it went
until it disappeared
into the great blue sky.
