It looks a lot like one of my least favourite birds but I hope it dosent sound like it. (the bird I am comparing it to (just the colouration) is the bell miner of Australia which has super high pitched calls and is very annoying while i'm trying to take photos of Animals at Melbourne zoo).
I know that warblers aren't related to honeyeaters i'm just making the comparisons between their colouration.
I love Wilson's warbler, though they are a bit hard to find (at least in WI). They love to show up in areas where Yellow Warblers are abundant, which makes them very hard to pick out.
