Pigeons in tiny cowboy hats are a mystery in Las Vegas

A rescue group named this pigeon Cluck Norris.

(CNN)People out West wear cowboy hats all the time. But pigeons?

Las Vegas residents spotted two of the birds around town in tiny cowboy hats this week. No one seems to know how the birds got the hats, but it worries a local bird rescue group.
Mariah Hillman, co-founder of Lofty Hopes, a pigeon rescue, told CNN it looks like the tiny accessories were glued to the animals.
    "When we saw them today, you could see some loose feathers in the glue around the hat," she said. "It's definitely a concern."
    The rescue group put out traps to try to nab the birds dubbed Cluck Norris, in the red hat, and Coolamity Jane, in the pink lid.
    The birds have become their own social media sensation, with Las Vegas residents looking out for the hatted duo.
    "I finally found one," Kassandra Flores tweeted with video of the hatted creature.
    Flores told CNN she didn't believe the birds were real until she spotted Cluck Norris in her mother's neighborhood Monday.
      "At first it was outside my door and I was excited ... but before I could get a video, he flew away," she said. "And then as I was leaving I [saw] him again and was able to get a video."
      Rumor has it a third bird in a brown hat is out there, but Hillman said her group hasn't been able to confirm it.
