It's interesting how some of the early migrant finds (like Warblers) turn up
north of southern OR first (at least first to be found by someone). Have a
theory on this. With the nice weather we have been having (like the clear
nights with some moon shine) there's not many "fall out" birds...they just
high-tail it to their nesting locations, which can be well north of southern
OR. It take some overcast, bad migration weather for them to drop out in
numbers to be found in a lot of areas.

Joe,
Thanks for the info. I did misunderstand but it makes sense, anything unusual
is flagged. I think it is a great idea to share the list with OBOL, so
sightings can get some peer review (I bet those eBird reviewers can get busy!).
The kingbirds may be a bit early but I wouldn't have any question on those, the
Swainson's Thrushes though seem a few weeks earlier than the usual "early"
records the last few days of April. I did see in Birds of Oregon a record from
2 April as the earliest and the regional eBird bar chart shows them showing up
the last week of March, but I would think those real early sightings could be
suspect but maybe they happen? I did point counts at New River in SW Coos for
15 yrs. and have worked in the Coast Range east of Coos Bay since 1988, and
have never seen one early than the last week of April but they could arrive
earlier inland?
I will say that many migrants arrive much earlier in the valley than on the
coast (BT Gray Warblers for instance).

Hi folks,
There is a misunderstanding of how eBird’s rare bird alert works. It’s
definitely “buyer beware” when it comes to the rare bird alert, because the
alert includes reports that are under review by the reviewers and which will
probably be invalidated. No reviewer looks at the report before it goes onto
the rare bird alert. They probably hear about it at the same time it shows up
on the rare bird alert. If anyone anywhere in Oregon misidentifies a Hermit
Thrush as a Swainson’s Thrush, it will show up on the rare bird alert. This
does not mean that it will end up on the eBird bar charts and other records. If
the report is later invalidated by a reviewer, it will not show up on the bar
charts or other eBird data. It does remain on that birder’s personal record
unless they decide to delete or change their identification based on feedback
from the reviewer. I hope this clarifies the misunderstanding some have about
how the rare bird alert works.

Swainson's Thrushes in early April- I am surprised this made it onto the
rare bird alert? I would think that whoever covers Benton County would have
caught this one.
Of course once a sighting like this makes it into eBird it could pass as a
new early spring date for OR and could cause a lot of confusion with less
experienced birders and result in quite a few more Swainson's being reported in
the next few days. Our earliest Coos date is the last few days of April.
It will be interesting to see when the first C. Nighthawks get reported...
