A puzzling optical illusion has appeared in the sky, with people puzzled by a bird that appears to have the face of a seal.
The unusual photos show a thistle, looking bloated as it fills its face with hundreds of insects.

It has been seen partying in flight at Tices Meadow Nature Reserve in Farnham, Surrey.
Photographer Jon Hawkins, 60, explained that chives, which can reach speeds of almost 70 km/h, can contain more than 1,000 insects in a throat pouch at one time.
The insects are held together by saliva and this is called a bolus, which makes the appearance of the bird’s face appear distorted.
Your catch can be retrieved and fed to the chickens.
Jon, who lives in Ash, Surrey, said: “The call of swifts when they gather in large numbers to feed is known as a ‘whoop party’ and sounds like a shriek.
“Chips spend ten months of the year in flight: eating, drinking, sleeping and even mating in midair, landing only to nest.
“Some fledglings won’t land for up to two years after landing, so you’ll never see them sitting anywhere other than the nest.
“I think the chikula looks like a winged seal or a bulldog-headed bird.
“I like images to show something that isn’t visible to the naked eye because they move so fast.”
Other amazing optical illusions include this image of a heart hidden among elephants.
And you could be the record holder if you manage to find it in under 20 seconds.
Another illusion is said to reveal how your brain can lie to you.
The trick is to make us perceive a black and white image in color.
Meanwhile, this optical illusion will tell you how dirty your mind is.
