Goldfinch or Pine Siskin? or Yellow rumped warbler

A pair of these showed up at the birdbath and I really did not know what they were. One had a yellow green feathered coat and the other had less color.
It was so windy here nothing wanted to come out and play. Rough day trying to
capture something with clarity. These were all rather dark and soft looking.
I was using my little sony while my canon is in the shop.

Just heard on the news New Zealand has had a bad earth quake. Please pray for all of our fellow blippers that live there.
