Acting quickly, the homeowner, who lives in western Wisconsin just outside Minneapolis, managed to capture on camera some of their lightning-fast parries and counter-ripostes.
Despite their feisty nature, hummingbirds are delicate little creatures, he added.
They weigh less than a penny, but their little wings beat ridiculously fast, up to 80 times per second, burning loads of energy. So to make their yearly migration they have to eat their whole body weight in nectar or sugar water every couple days.

That explains why they’re so territorial. These highly-energetic and thirsty birds are protective about readily available food sources.
Last month, Emmerich managed to capture a sequence of shots displaying acts of aerial jousting worthy of an Olympic fencer—only much faster. Ten photos he snapped in one instance spanned a mere three-tenths of a second.
He saw one bird dart towards another, then he immediately clicked the shutter and could only hope. Remarkably, the photos revealed an intricate jiu-jitsu-style sequence compressed into the time it takes to blink an eye.










Emmerich’s Sony A1 version 2 camera can shoot 30 frames a second, he says. He used a 300-millimeter lens to capture incredible detail.
But his fascination with the fragile and mildly ferocious hummingbird led him to set up two feeders in his yard in Wisconsin. As their competitive behaviour became more noticeable, he decided to zoom in on the action.
Waiting hours by the feeder during evenings last month paid off, and he caught the birds’ skirmish with his camera. But the action hasn’t stopped since then. Soon, another aerial battle ensued, which he photographed.

“They were fighting like crazy, flying all over the place for several minutes,” he said, adding that the bout went to the ground like mixed martial arts. “The one female is holding the other female down on the deck by the beak.”
He says both photo shoots “exceeded my expectations,” so he posted them for the hummingbird community he belongs to on Facebook, and it went viral.
“Three days later, it’s still constantly getting comments,” Emmerich said. “I never expected to see that clear photos of it.”
