Taken in Feb could this be Wilson’s Warbler?
Many thanks

One concern: why is the underside of the tail in the second image so dark? most images shows this part to be medium grey and not blackish.

I thought that was odd as well. I went looking around the internet and it does seem unusual for this species. The bird in question is 100% a Wilson's warbler though. Every feature matches C. pusilla. I did come across this photo on naturalist with a very black under tail as well.

It's just shadow. Note the paler oblique band (highlight)
