Rock Pigeon

Rock pigeons  typically display 'clean legs'.

Unlike the following with thick feathered legs.

Another with hint of its thickness on the way.

AI Overview:

Rock pigeons with feathered legs (often referred to as "muffs" or "leggings") observed in Malaysia are 

domesticated, fancy pigeon breeds that have escaped or been released, rather than a natural wild species. While the common rock dove (Columba livia) typically has scaled, unfeathered legs, these specific variants carry genetic mutations that cause feathers to grow on their feet. 

Perhaps, two cases of interbreeding in the above sighting.
