A mysterious, unidentified flying object over Semiahmoo Bay has caught the attention, and imagination, of some White Rock residents.

Matt Kilback first reported seeing the unusual object to a White Rock Facebook group last week.

Kilback, who was asking if anyone else saw the 91裸聊视频渁nomalies91裸聊视频� that took place Dec. 15 afternoon, reported seeing what he initially thought was a waterspout forming.

In an interview with Peace Arch News, Kilback said the morphing object first looked like a plume of smoke or mist.

91裸聊视频淪uper saturated, dark, low-hanging, free-moving cloud that looked like it was trying to touch down on the water to form a waterspout. Up above it, there were literally circle clouds,91裸聊视频� Kilback said.

91裸聊视频淎s soon as it touched the water, it would start pulling water up and then it would collapse. And then it would disappear for a second, almost as if it would go into the water, and it would start reforming again in another spot.91裸聊视频�

Kilback said the object was about 2-5 kilometres out in the bay, but says he got a pretty decent look at it coming out of the water.

91裸聊视频淚t was forming like a sort of funnel shape sort of thing. And then it completely came out of the water, and it came probably a few hundred feet up, and then it came back down and it totally submerged itself and formed, it looked like, a solid formation under the water. And then it started moving without making any splashes. It wasn91裸聊视频檛 disturbing the water at all, but you could see clearly it was a round object that was submerged right under the surface of the water and it was moving incredible speeds.91裸聊视频�

Shannon Stewart, who also observed the unusual object, described it as 91裸聊视频渞eally weird.91裸聊视频�

91裸聊视频淭here was a dark shadow moving across the water, then it would disappear and reappear moving in the other direction. This went on for a long time,91裸聊视频� Stewart told PAN.

91裸聊视频淲e used binoculars to look because we thought it was a whale in the bay or a flock of birds, maybe. But we couldn91裸聊视频檛 see any birds, but there was something at the tip of the shadow coming out of the water like a seal or something.91裸聊视频�

Asked if what Stewart observed could have been a submarine, she said no.

91裸聊视频淚t definitely wasn91裸聊视频檛 a submarine. It didn91裸聊视频檛 move like a submarine at all.91裸聊视频�

Kilback offered two theories, suggesting the object was related to US Navy technology or it was extraterrestrial.

91裸聊视频淚t looked like either nano-tech, or it was ethereal, man. I91裸聊视频檓 telling you. I do believe that we can91裸聊视频檛 be the only ones in this universe. You can91裸聊视频檛 help but think aliens, man,91裸聊视频� Kilback said.

Contacted by PAN, White Rock Sea Tours owner Andrew Newman, who has spent countless hours in Semiahmoo Bay, weighed in on what the object could have been.

Newman said when the atmospheric conditions are just right, objects in the water 91裸聊视频� such as a vessel 91裸聊视频� can appear distorted.

91裸聊视频淚t looks like a mirage,91裸聊视频� Newman said.

Another theory, which Newman agreed is most likely, is that it could have been a flock of birds.

91裸聊视频淚91裸聊视频檝e seen that in the distance, and that is ridiculous, too. That looks like a flying saucer,91裸聊视频� Newman said.

Local photographer and birder pointed to Dunlin, small birds that flock in numbers up to 40,000.

91裸聊视频淚 can totally understand why (some) think it91裸聊视频檚 alien or other worldly!91裸聊视频� Paton wrote to PAN. 91裸聊视频淏ut they91裸聊视频檙e tiny little birds!91裸聊视频�

Paton explained that the birds arrive over winter and move up and down the coast in great numbers before returning to the Arctic in the summer.

91裸聊视频淎s they turn and catch the light they seem to disappear for a while but then catch the light 91裸聊视频� black and then white 91裸聊视频� absolutely brilliant to watch,91裸聊视频� she wrote.

Paton said the birds are about the size of a thumb.

91裸聊视频淭heir dance or murmuration is usually a defence manoeuvre to evade peregrine falcons,91裸聊视频� Paton wrote. 91裸聊视频淭hey flash and swoop and vanish and try to trick the falcon.91裸聊视频�

Kilback, however, isn91裸聊视频檛 convinced.

91裸聊视频淭here91裸聊视频檚 no chance it was birds. Not at all, man.91裸聊视频�
