A 59-year-old woman grabbed her camera after spotting a murmuration of starlings while out for a walk.

Helen Day said the flock looked like a "dark spell" drifting across the grass, near Bangor in north Wales.

The language teacher and curator from Hertfordshire, England said "It was mesmerizing—like a dark spell drifting across the land."

And, it sounded like the rush of the sea. "I'm no bird watcher, but it was really freaky to me.

"It was just a happy accident that I caught it on camera."

She was on vacation in late October when she witnessed the murmuration, which occurs when a flock of starlings, which may include other species from other families, exhibit a swarm behavior in a large flight formation.

"It felt like I had the whole world to myself in that moment."
