The animal kingdom has some weird-looking individuals.

And one bird in Singapore certainly looks pretty out of the ordinary.

Durian bird

Photographed at Gardens by the Bay, this unusual bird has been colloquially dubbed as the 'durian bird' by the photographer.

It's not hard to see why. The appendage on the avian's face looks almost as if it has been photoshopped with a piece of durian or cheese on its face.

Here's what a close-up of its face looks like:

The bird was not alone—it was spotted with four chicks as well.

The baby chicks are pretty cute.

The bird can be spotted at several places around Singapore.

Here's one of it staring at a reflection of its durian face.

And here's a behind-the-scenes showing the antics bird enthusiasts get up to when photographing the critters.

Apparently escapees from the Singapore Zoo

As strange as it might look, this species of bird is actually not that rare in Singapore.

Called the masked lapwing, its name is derived from the rather prominent, fleshy yellow wattle on its face.

They are also known as spur-winged plovers due to the sharp spur on the joint of their wing, which they use to attack other animals.

Quite metal.

The species is native to Australia and New Zealand, but individuals here are believed to be escapees from the Singapore Zoo.

They allegedly broke out when a tree fell on their enclosure, creating an opening with which to escape from.

According to the Bird Ecology Study Group, the populations of the masked lapwing have increased over the years, with one bird enthusiast reporting sightings of flocks of up to 18 individuals in 2013.

These birds can now apparently be found at Mandai, Seletar and Tanjong Rhu, and around the Central Catchment.
