EL PASO, Texas -

Is it the screeching of birds of prey or could it be something else?

The wild bird sounds can be heard echoing through parts of downtown, and many are baffled.

ABC-7 was at the intersection of Campbell and Florence streets where the reports have been running rampant.

Some people claim seeing a Monstrous bird, up to 10 feet in width.

Others say it's not of this world.

"I was really scared because I didn't know what it was. I was like, 'a UFO?'" said one downtown jogger.

"I saw it," said Brian Limon.

"I was running down here," a jogger told ABC-7.

"10 feet long," said Limon.

"And it flew over here. It was crazy," Limon continued.

"Fire out of its eyes," the jogger told ABC-7 with fear.

"All of a sudden I heard this bird, like, caww!" said a 12th-grader from a nearby school.

"Call the goverment or something," said the jogger.

But even government officials were baffled.

Claims of birds of prey reported near a bus stop.

People confused.

An ABC-7 photographer on the scene to captured the sounds.

ABC-7 investigated and we found the culprit.

Sun Metro.

"As you can hear in the backround, Sun Metro installed a device," said Sun Metro spokesperson Laura Cruz Acosta.

She tells ABC-7 the transit system was having a bus-stop pigeon problem.

"We would have the ground and the benches and the area around where passengers wait covered in pigeon feces," said Cruz.

So they set up a sound system that would prevent the build-up of pigeon poop.

"What you hear are different monkey sounds, different birds of prey sounds that the pigeons are actually afraid of," said Cruz.

Cruz tells ABC-7 the audio playback is drastically improving the condition of the benches and the surrounding areas.
