YOU have the eyes of a hawk if you can spot what's unusual about this London tree.
If you gazed over the photo you'd think it was merely a snap of a leafy tree on a winter's night.
The leaves appear to have fallen from the lower parts of the tree, but the green foliage remains strong over the majority.
Then, on further inspection, you'll realise what you thought were bright coloured leaves are actually parakeets.
The shots of the bright green birds were snapped last night after the parrots swarmed trees above a South London BP garage.

Both of the chestnut trees shed their leaves in winter, but you wouldn't have thought that yesterday.
But once you realise the leaves are in fact ring-necked parakeets, you can't unsee it.
The bright green birds had all gathered in that one spot above the petrol station and Subway near Mitcham Common on Mitcham Road.
There are many optical illusions floating around on the internet.
An photo of a tree went up online recently, promising something furry was hidden in the leaves.
One recently surfaced of a four-letter word hidden in an image in a TikTok video.
Another TikTok clip showed people merrily kayaking in the ocean, but there is a predator hidden in the water.
And, another surfaced of four animals camoflaughed in four nature pics.
