Thanks for this video, Luc!
I posted this to Birdchat yesterday (and will add it to the Youtube comments):
It's exciting enough when a rare stray shows up somewhere in your area, but
this one was about a block and a half from my house. The exact location,
provided by Mike Burrell of OntBirds, was 43.558117, -79.686342
(https://goo.gl/maps/AJRp5efzc9mAKH5A6), at the back of Shalebank Hollow Park
in Mississauga, Ontario.
The bird is almost certainly a Yellow-browed Warbler (Phylloscopus inornatus),
a Siberian species that previously hasn't apparently gotten any closer to
Ontario than Wisconsin (in 2006). It winters in Malaysia, where I've seen lots
of them, but I (and many other birders) had to go and take a look anyway (and
take, in my case, the attached much-cropped record photos). Phylloscs are
notoriously difficult to identify, but on checking my photos I concur with the
identification. Not only is this the likeliest species on the basis of range
and migratory pattern, the presence of two strongly-marked wingbars and other
features eliminates Arctic Warbler, and what appears to be a mostly-dark lower
mandible eliminates possible alternatives such as Two-barred Warbler
(Phylloscopus plumbeitarsus), Eastern Crowned Warbler (Phylloscopus coronatus)
and Greenish Warbler (Phylloscopus trochiloides). The very similar Hume's
Warbler (Phylloscopus humei) is unlikely on the basis of range and migratory
pattern.
A Yellow-browed Warbler was recorded in British Columbia in the fall of 2019.
The closest previous record to Ontario would appear to be a bird recorded in
Wisconsin in 2006. See
https://ibis.geog.ubc.ca/biodiversity/efauna/documents/YBWA-article-RT.pdf for
an account of the British Columbia record, with detailed identification notes
and photographs.

Hello Birdwatchers: Yes the Mega Mega rarity, Yellow-browed Warbler found by
Pat Hare, was seen all day yesterday. Here is a video to explain identification
points. Enjoy
