What is this small hovering bird with a yellow throat, breast, and belly, and a brown back and head, found in the Philippines?

Question

What are these small birds in the Philippines that can hover like hummingbirds? They had yellow throats/necks, chests, bellies, slightly curved beaks, and brown backs and heads. They were only slightly bigger than a human thumb. They are not commonly spotted in the area where these pictures were taken.

I searched online and found a Wikipedia article about the yellow-bellied whistler AKA Philippine whistler (Pachycephala philippinensis), a bird that looks similar and is endemic to the Philippines. However, the picture in the article showed a bird with a straight beak and no yellow throat. So I’m not sure if these birds are the same species or not.

These photos were taken on May 28, 2023, in a rural backyard located in Western Visayas, Philippines. The area is abundant with plants and trees. Due to the proximity of a typhoon, the weather was cloudy and windy, and it started raining shortly after these photos were taken. The birds seemed to be a couple, playing and hovering around a guyabano tree.

Answer 1

Looks like it is a female or possibly juvenile olive-backed sunbird (Cinnyris jugularis), based on pictures on the web. I ID'd it by searching "birds phillipines" in google and flicking through a couple of links. The distinguishing characteristics are the curved beak, olive-green back and the small pale bar over the eyes.

This is a common species of bird throughout SE Asia and even into Australia.
