.. need help with this one

[Grenfell]

I think this one is a blue-winged warbler, but there seems to be a lot more white on the under belly than I would have thought, but it does have the black eye line I would expect.
Any help appreciated

Yellow throated vireo. Nice find!

Where was this and what was it doing?

it looks a lot like a Yellow-throated Vireo.

Many thanks ... Now that I look closer at the beak I can see that this must be a Vireo - A lifer for me
