Fall warbler - Alberta Canada (1 Viewer)

[KhostAdenplusmore]

Today I noticed a few (perhaps 4) New-World Warblers flitting through a windbreak along agricultural fields in central Alberta. I am not sure what species they were. I did get a couple of photos of one of them, and am still stuck between Tennessee Warbler and Orange-Crowned Warbler. Does anyone have a thought about this? Thanks.

A couple other features in favour of Tennessee included the more distinct supercillium and the hint of white-ish spot in the inner edge of the tip of the tail
