Great Blue Heron

Fascinating facts about the Great Blue Heron

• A great blue heron can swallow a fish longer than your hand in under a second — their throat expands like a elastic bag, and their oesophagus can stretch to accommodate prey almost as wide as their own body. They hunt by standing motionless for minutes, then strike with the speed of a boxer's jab, their needle-sharp bill accelerating from rest to full speed in 50 milliseconds. This patience-then-explosion strategy works so well they catch fish in water too murky for their eyes to penetrate; they feel vibrations in the water with specialized receptors in their bill.
• At 4 feet tall with a 5-and-a-half-foot wingspan, the great blue heron weighs less than 5 pounds — they are a masterpiece of hollow bones and air sacs that make them lighter than the water they hunt in. Their skeleton is so delicate a strong wind can pin them down, yet they can carry a 1-pound fish in flight without changing course. This extreme lightness is why they move like a pensioner crossing a street: every step is deliberate, every muscle calculated to avoid wasting energy.
• Great blue herons were hunted to near extinction in the 1800s for their plumes, which Victorian fashion demanded for hats and dresses — a single breeding plume could fetch the price of a working man's week wages. Their comeback is one of North America's quietest conservation wins: from a few thousand birds in 1900 to around 300,000 today. They colonised cities and suburbs, nesting in trees above shopping centres and highways, proving that some wild animals will live alongside humans if we simply stop shooting them.
• A great blue heron's neck has 17 vertebrae — five more than a giraffe's — which lets it fold into an S-shape so tight the head tucks between the shoulders during flight, cutting wind resistance by 20 percent. On the ground, this serpentine neck can extend to full length in a fraction of a second, turning the whole bird into a living spear. This design allows them to hunt from impossibly shallow water, accessing fish their competitors — cormorants, diving ducks — cannot reach.
• Breeding great blue herons make a sound like a broken dinosaur — a harsh, guttural 'fraaaaank' they repeat while throwing their heads back, their plumage bristling like a velociraptor's crest. Males build platforms of sticks in tall trees and perform this display to attract females, clapping their bills 16 times per second during courtship. These colonies, called heronries, can contain 50 or more nests stacked in the same tree, creating a raucous, foul-smelling city that transforms quiet wetland edges into living amphitheatres.
