I asked AI for a helping hand, it came up with Saffron Finch, Here’s why:

• Overall yellow color: The bird is predominantly yellow, which is a key characteristic of the Saffron Finch.
• Orange on the face: Note the orange forehead and lores (the area between the eye and beak).
• Greenish tinge on the back: Saffron Finches often have an olive-greenish wash on their back and wings.
• Location: Saffron Finches are common in Hawaii, where you took the photo. They are an introduced species, originally from South America.  

While it’s possible it could be a similar species like a Yellow Warbler, the orange on the face and the location make the Saffron Finch the most likely identification.
