Further investigation has found the following recorded observations in
Klamath Co.:
near Chiloquin, August 8, 1994, by Greg Gillson (furthest north and
east for Klamath Co.)Malone Springs (along eastern base of Cascades
near Rocky Point), Oct. 14, 2007, by Frank Lospallutonear Caledonia
Canal trail/road; Howard Bay area of Upper Klamath Lake) June 18,

Falls, December 27, 1981, count tallyKlamath River Canyon, below

The Klamath River Canyon, near Moore Park, and near Caledonia Canal
trail are within the furthest nw extension of the habitat in Klamath
County, and which Hutton's Vireo seems to favor. The other two
observation in Klamath County: Malone Springs and Chiloquin are quite
a distance from those other three locations. No other records east of
Hwy 97 in either Klamath or Lake Cos. are known to me, so overall, it
appears that Hutton's Vireo observations are generally not that far
east from their normal range.
The Oregon Birds AGR book mentioned that Hutton's Vireo is found in
the forested areas of the sw portion of Klamath County, but without
sources or references. On the same page is an atlasing map with
hexagons showing the results of survey/inventory previously done in
Oregon. Some of the hexagons' boundaries where there were occurances
for Hutton's Vireo are spilling over the Klamath County line. I'm
presuming that the comment may have come from interpreting the
hexagons as occurances in Klamath County, but the hexagons actually
had observations in Jackson County, but the hexagon with observation
in Jackson County overlapped into Klamath County, but that overlapping
portion did not have an observation of Hutton's Vireo. Just
speculating on my part. It's possible that the author had information
that was accepted as general knowledge, but I am not aware of Hutton's
Vireo records in that area of Klamath County.
Looking at the range maps of Hutton's Vireo on ebird, I noticed that
the SW population, down in the desert portions of California, seems to
have records much further away from their normal habitats where they
are found in the southwest. Since the Hutton's Vireo has very few
records in eastern Oregon, or east of the Cascades, away from their
populations west of the Cascades, and/or without significant
distances, I think Wayne Hoffman has a point that the recent record of
Hutton's Vireo could be an individual from the SW population given
their tendancy to move further from their normal range. It would be
interesting if that recently observed bird was relocated and a
recording of their vocalizations was obtained for comparison.

Hutton's Vireo was heard and seen down in the Klamath River Canyon
by Frank Mayer, I'd say about 15-16 years ago, in March I think, but
the exact date I'd have to look up. The habitat down there includes
Oregon White Oak, and low elevation conifer such as Ponderosa Pine and
Incense Cedar. I was able to get down there later to also hear and see
it. Since this location is connected geographically and with connected
habitat, I have considered it the eastern most detention of its range.
But, I haven't encountered that species again down there despite many
trips and surveys. There is one other record that I'm aware of, on a
Klamath Falls CBC, back in the very early '80s. I'd have to look that
exact date up also. The location is about as far east as the Klamath
River Canyon "type" of habitat extends into the basin. The location
however is out of the canyon and in this transition zone. So, this
winter date of the CBC date can support the recent observation date in
a location east of their normal range.
I wonder if those dates for Klamath Falls are in Oregon Birds AGR.
I'm checking.

Not sure how far east they get in Klamath. I think only on the
east slope of the Cascades. Perhaps Kevin could bring us current on
that.
There are multiple reports from Malheur but I don’t think there
is a good photo. There may be one poor photo from maybe the late 1990s
- anyone remember that?
As far as I know, yours is the first solid record east of the
forested Cascades. Pretty amazing to have one far out on the
wheat-plains.
Can someone enlighten us as to any records in e. Washington?

During a brief stop in Arlington today, while birding the park
across from the gas station, I was shocked to hear the whinny call of
a Hutton's Vireo coming from a small pine tree. My mom and I were able
to track it down and get photos. As best I can tell, this is a first
record for Eastern Oregon.
