The US specializes in urban jungles. LA, New York, and Chicago all personify types of urban jungles. They all have areas that are asphalt jungles. Full of hard surfaces and danger. Los Angeles, especially since they concreted over most of the city in the first half of the 20th century. All three specialize in plenty of urban violence, which is epidemic throughout the states.
Here in Portugal, we have entirely different types of urban jungle.
There are oases of greenery everywhere if you know where to look.
And then there is the wildlife. Avian wildlife predominates. Followed closely by cats and dogs coming in a distant third. (We are talking urban wildlife here. The number one spot, of course, goes to the humans. Far and away the most dangerous of the lot!)

I have mentioned the Atlantic seagulls before. They really are kings of the coasts. As near as I can tell, man is their only predator. The Portuguese Atlantic gulls can be vicious pigeon killers. It is actually pretty scary to witness. And with so many pigeons, the gulls will never go hungry. I wonder if pigeons are a delicacy to them since they mostly eat fish. It is pretty horrifying to hear the screams of the city rats when the seagulls go after them. I have seen them feed their chicks with fresh rock dove meat. Yum. It gives one new respect for the seagoing warrior gulls. And the screaming of the sea pterodactyls is near-constant in the cities near the coast.
On a lighter note, we have what seems like a flock of parrots in the neighborhood. They fly by so quickly, it is hard to tell if that is what they are. Given their screeching and small green bodies, we guess they must be renegade parrots. Songbirds are very popular as pets here and, you know they must escape from time to time.

When it comes to screeching, there is nothing like a peacock. The peafowl really makes the most Jurassic park sounding noise. Several parks have them in abundance and, they tool around like house pets in various parts of town. It is entertaining to see.
We hear about the shootings du jour in the US, and we think, wow, it just seems to keep getting worse in the not-so United States. We are happy to have traded the concrete jungle for a peaceful urban oasis.
