Monitor lizards can be seen roaming the streets and walkways of many city parks in Thailand. These lizards can be quite large, as big as 5 or 6 feet in length. They mostly keep to themselves, shying away from people who get to close. I have seen them eating dead fish and turtles in the Lumpini Park which is near where I live. On several occasions I have seen them fighting among themselves, in what I assume is related to their mating rituals. This picture shows two of the bigger guys in what appears to be hand to hand combat.
