"We were just instructed to take a bunch of photos so that's basically all I did. I was kind of lagging behind the group and putting myself in different positions," Mausling told InsideEdition.com. "I was standing on top of the stairs when I took the picture. I just took a picture of a wall a couple times and under the staircase. We looked at the photos later and sure enough, we caught something. "

That "something" was what appeared to be a little girl in a white robe walking up the stairs of the hotel, but no one from the tour remembers seeing a child.

"At first I thought maybe a little girl ran by," said Jessica Mausling. "I was in shock. How could all of us miss her, especially a little girl in a white gown?"

Jessica said she contacted the hotel and the tour guide said she did not recall seeing the little girl either.

"By no means did anyone see a little girl in what looks like her pajamas and her slippers walking up the stairs right in front of us," Jay Mausling said. "Even if you look at the picture, you notice [that] no one is looking there. You just don't excuse something like that. My initial reaction was, 'No way!'"

Mausling said he's shown the picture to friends and co-workers and some have suggested he changed the photo in some way.

"People are like, 'You photoshopped this' and I am like, 'I don't even know how to use my cell phone,'" Mausling said. "I couldn't believe it and everyone I show finds it hard to believe."

A man claims that he saw two birds "the size of airplanes".

Manuel Ponce, a 48-year-old HVAC technician from Virginia, told Cryptozoology News on Wednesday that he was on a cruise with his family and church members when he saw the flying creatures.

"It happened right after 9/11," Ponce said. "We had just booked a cruise with Royale Caribbean in January of that year. We had 28 members of our congregation," he added.

The man claims that after a strong tropical storm, the captain managed to land in San Juan, Puerto Rico.

"We arrived there in the morning. The day was on and off, rainy with spurts of sunlight every hour or so. We hired a guide for half a day, he took us to some places of interest.

As the guide took the group near a beach, Ponce explains, they noticed a "a real dark rolling rain cloud coming quickly".

"That's when I saw them. At the very top of the storm cloud... I saw two giant birds. I pointed up to everyone in the group, including now my ex-wife and the guide, but the birds went straight up."

The man described the creatures as birds "the size of airplanes" with a 30 foot wingspan. Their necks were surrounded by a "white ring" and they had straight beaks.

"Their wings were straight, with feather protruding at the ends of their wings," he recalls.

The alleged sighting reportedly lasted about five seconds and Ponce said he was the only one to see the flying animals. He added that he tried to snap pictures but that he had not enough time to capture the image.

And Ponce, who says he has told the story to his congregation, friends and family, says most of them don't believe him.

"Only my two sons believe me. I know what the hell I saw," he said.

Thunderbird, also known as Roc, is the nomenclature used by Native Americans to refer to bird-like creatures with reptile features that are believed to be related to the extinct pterosaurs.

In August 2015, a man in Michigan claimed to have seen a "giant bird" with a 10-foot wingspan.

In July 2015, two people in Nevada reported seeing a creature that reminded them of a pterosaur, a flying reptile believed to have gone extinct about 65 million years ago.

Two weeks later, a minister and her daughter claimed to have seen an unidentified flying creature that looked like it was "straight out of Jurassic Park".

In October 2015, a California man snapped a photograph of what he believed to be a "prehistoric bird".

In 1890, Arizona newspaper The Tombstone Epitaph wrote about two ranchers killing a "winged monster" similar to an "alligator" in the desert between the Whetsone and Huachuca mountains.
