There are a lot of them here in the Philippines. We named it Bayawak(the first picture).
Yes, there are many, as I said in the post: "The monitor lizard is common in Southeast Asia".
The second creature is a giant squirrel, it isn't that rare either but doesn't live in Bangkok sewage like monitor lizards do 😁
A big bat here in the Philippines
The third creature and babies aren't bats but flying squirrels. The beasts in my images fit the description of Laotian giant flying squirrel found in 2012 in Central Laos. I took the images in Central Laos too so it must be the same species; this is a rare one.
