One of the most common city birds around the world with plenty of variations.
These calm birds have a tendency to go go under covered areas in peoples roofs and overhangs, perching along dry elevated areas to roost. Unfortunately these calm and funny birds are severely dirty. They process food at a very fast rate, leaving plenty of feces where ever they are roosting.
Not the most clean of birds, they do not care at all existing in their own excrement. Similar to rats, they feed primarily on human scraps and waste.
If left unchecked these birds can cause health risks due to the high volume of droppings they leave behind.
