Just days away from Halloween, Yukon is now like a scene out of Alfred Hitchcock's worst nightmare.
They've been the talk around town for days.
"What's going on with all the birds?" asked one man, as birds filled the sky. "I didn't know if they had some crumbs out here, trying to feed them."
"The sky was just totally black and, then, they all landed here," said Louise Terry on her way to lunch.
Many in town said hundreds, if not thousands of birds descended on Yukon around a week ago.
Experts said the massive flock is likely in mid-migration.
"Looks like most of the birds in that picture were probably brown headed cow birds," said Senior Biologist Dan Reinking with the Sutton Aviation Research Center. "It's only in the fall and winter months when they come together in large migratory flocks like this."
On Tuesday, these birds of a feather flocked to Johnny Carino's, covering the roof and surrounding trees.
"All over this area, just birds everywhere. I don't know if it's a migration, but it's insanity," said Kent Weaver, the restaurant's general manager. "I don't know how long they're going to be here, but they can go."
The birds have sparked curiosity, disgust and even comparison's to an Alfred Hitchcock classic.
"It looked like something off of one of those old school movies - 'The Birds,'" said one bird watcher.
"It's like that movie with the invasion of the birds," Terry said. "Crazy stuff in Yukon, Oklahoma."
Other than their droppings, Reinking said there's no reason to fear the birds.
"People might have their cars get dirty from a large flock like that," Reinking said. "Other than that, they don't really cause any serious problems."
Officials said the birds could stay in the Yukon area for around two weeks and it's common for flocks to occasionally migrate to populated, urban areas.
