The baby munia is a different color than its parents, has the little yellow fold "baby gape" in the corner of its beak, plus its parents were feeding it at the time. The prinia was also still getting fed by its parents and is also a different color than the adults.
The first pic is an adult scaly-breasted munia, the second is an adult yellow-breasted prinia

thank you, @birdingnut, i can see the difference now, & of course, if they still get fed by mom & dad...

That's why I moved here in 2010. One of my Thai Morehead University students showed me photos of birds he'd taken at Khao Yai National Park and I told him I'd go there to do bird photography some day. So I did.

@birdingnut I was so excited to go to the Philippines for my Peace Corps Service because of the extraordinarily beautiful birds. Even the pictures of the pigeons were a full pallet of vibrant colors. When I got to my island, I saw nothing my but Mynas. Nothing. I was lucky enough to spot what I am pretty sure was a Monkey Eating Eagle way up in the sky, but it would have been a rare find. I asked the locals about where all the birds had gone and the common answer was that during WWII, pretty much everything living was either shot or trapped to be eaten. Didn't make sense given there of 7,100 Islands. But I was quite disappointed. I had to go to the aviary in Manila to see the birds. Same as when I was in Australia during an unusually cold and rainy December.. I could hear parrots and cockatoos, and other birds but never saw one in two weeks. For a person who likes to travel for wildlife first and culture second, I wa pretty bummed. So, I have to go back. I did see some English Sparrows, at least I think they were English. Those accents British, Australian and New Zealand are difficult for me to discern sometimes.

@Dingodog Yes, that is a problem in Asia and Australia and Tasmania..they actively kill birds. In Asia they eat them, and in Australia they poison and shoot them to protect their crops. The best country to see undisturbed wildlife is Mexico, since the culture doesn't acknowledge them as important enough to even name the species. They simply don't "see" them.

Mexican people ignore the birds and wildlife because to them, they "don't matter." I once asked a Mexican what a particular bird species was called in Spanish, and she glanced at the bird in surprise, shrugged and said "Pajaro (bird)."

I got the same response in Tasmania when I asked about a species of lapwing. It was a "bird."

@birdingnut That's funny. Same thing there. They would sell these captive finches with orange beaks and they were called birds. Like the mynas and the pigeons. Incidentally, I heard a tale that the street vendors would sell those finches and when they got away, they'd fly back to the vendors home for resale. Don't know if it's true.
