A Giant Made of Air
Standing four feet tall with a wingspan over six feet, a great blue heron looks enormous — yet the whole bird weighs just five to six pounds. Like all birds, its bones are hollow, a skeleton built for flight.
BLUEHERON.GALLERY
A season in the rookery — nesting pairs, families, and first flights among the Montana cottonwoods, photographed from the air.
Most people meet the great blue heron alone — a solitary silhouette at the edge of the water, motionless, patient. But every spring these quiet hunters gather in the treetops to do something remarkable: they build a neighborhood. For one season I photographed a single rookery in the Montana cottonwoods — the courtships, the stick ceremonies, the crowded nests, the awkward teenagers testing their wings. Every photograph is an invitation to look closer, to learn, and to protect the wetlands these birds depend on.

DISCOVER
Standing four feet tall with a wingspan over six feet, a great blue heron looks enormous — yet the whole bird weighs just five to six pounds. Like all birds, its bones are hollow, a skeleton built for flight.
In flight, a heron tucks its long neck into a tight “S” and trails its legs straight behind. That silhouette is the easiest way to tell a heron from a crane, which flies with its neck fully extended.
Specially shaped neck vertebrae let the heron coil its neck and strike with astonishing speed and precision — spearing or grabbing fish faster than the eye can follow.
Herons grow “powder down” feathers that crumble into a fine powder. They rub it into their plumage to soak up fish slime, then comb it out with a fringed claw on the middle toe.
Great blue herons nest in treetop colonies called rookeries — sometimes a few nests, sometimes hundreds. Colonies return to the same grove year after year.
Courtship revolves around sticks: the male gathers them one by one and presents each to the female, who works it into the nest — one of the great rituals of spring.
A portion of every print sale supports wetland and riparian habitat conservation — the waters these birds cannot live without.

“The heron teaches a kind of patience the river already knows — stand still long enough, and everything you need comes to you.”
