Two different warblers

I felt that I was able to nail down, more confidently now, the differences between the Eastern Crowned Warbler and the Arctic Warbler:

Eastern Crowned Warbler:
- yellowish-green upper feathers, whiter underparts, more yellowish under-tail part
- beak with no black tip to lower mandible
- clear median coronal stripe on rear of darker crown

Arctic Warbler:
- olive-green upper feathers, more greyish underparts especially at neck
- distinct dark tip at lower mandible
- cleaner orangey legs
