Why aren't pigeons scared of humans like other non-domesticated animals?

I know that many other animals (foxes, squirrels, mice etc) have lost the 'fear' in big cities, but pigeons seem ubiquitously fearless even in towns and villages.

Actually, the pigeon species you probably mean is called the Feral Pigeon (Columba livia) because they are all derived from domesticated pigeons that have returned to the wild. Having no fear of humans seems to be a remnant of that.
