Oops – sorry about the wrong link. Yes, Jack’s link is to the bird that Bill
Clark is now calling a northern red-tail rather than a western.

Sorry for the delay in responding, Bob. It was the bird first posted by Jack

was a western, then I jumped in late and erroneously called it a Harlan's, and
now Bill Clark considers it to be a northern. Here's the link to Jack's

My apologies in advance for resurrecting an old thread, but I need to clear
my conscience. After reading Tom's comments on the red-tail photographed
by
Jack a couple of weeks ago, I asked raptor expert Bill Clark to look at the
pics. He said in no uncertain terms that it was NOT a Harlan's, so I
humbly
retract my declaration that it was. Hopefully, now I will not be seen as
epitomizing any one of several Mark Twain sayings about the fallacy of
absolute certainty.
Interestingly, Bill also said that this bird is not a light morph western
red-tail, but instead a light morph northern red-tail, spp. abieticola.
Unfortunately he did not provide his reasoning, and given my lack of
familiarity with that subspecies I'm somewhat baffled. But it is Bill
Clark,
so personally I would assume him to be correct unless demonstrated
otherwise. Northern red-tail is a somewhat mysterious subspecies. It was
first proposed almost 70 years ago but languished in obscurity for decades,
and in fact was not accepted by many experts. In the last few years it has
been written about more extensively (e.g. Liguori and Sullivan, 2014, North
American Birds 67(3): 374-383) and is now widely accepted as breeding
across
boreal Canada into SE Alaska, and drifting southward to some extent into
the
continental US during winter. In the images I've found of abieticola I
haven't seen a bird that looks like the one in question here, but that may
be an artifact of an understudied taxon. Also, Liguori (2001, Birding 33:
436-446) has written about the difficulty of assigning light-morph
red-tails
to particular subspecies, and it may not be possible in some cases.
Perhaps
this is one of those?
Finally, in a technical note about Tom's comments, the full scientific name
of western red-tail is Buteo jamaicensis calurus, and therefore the correct
abbreviation is B. j. calurus, not 'j.c. calurus.' Likewise Harlan's is B.
j. harlani, northern is B. j. abieticola, etc.

Hi Olin,
I have to disagree with your assertion that this bird being sized up as a
non-Harlan's is a "(can't see) the forest for the trees" situation. It's
more like: there are the trees; some are firs--- how do we reliably
distinguish which is which. It usually takes getting some details,
plural.
Just so with subspecies of redtails.
As regards plumage, I agree that the bird is sort of "cold" on the
upperparts but it's a brown-infused gray, not black and not so much as to
be disqualifying on that character alone to be out of the plumage-range of
J.c. calurus (there is a licensed picture on BNA taken by Jerry & Sherry
Liguori of a flying juv. western redtail that looks nearly identical to
this local bird). And on Jack's bird there definitely * is * a light buffy
wash apparent on the breast (not snowy white as would be expected on
light-morph Harlan's) as shown in the picture where the bird is perched;
so, no, it's not "basically a black and white bird". And so that kind of
undoes your next sentence: "That necessarily makes it a Harlan's".
If the bird, when perched, pic is looked at closely we can see:
brownish gray upperparts
that light buff breast
no atypical light coloring on the face/head and throat (as would be
expected in light morph Harlan's)
a belly band that is typical for western redtail and not "fairly distinct
blobby" streaks as Ligouri says occurs in light- morph Harlan's
inre the the leg feathering: it's totally fine for j.c. calurus
Lastly, I'll just mention that Jack took these photos right in the same
area that Ed McVicker found and photographed
( following his directions, I re-found it days later) a classic adult
light-morph Harlan's which ticked all the above-mentioned boxes. Turns
out that both Ed and I on different days saw what must have been this
very bird that Jack photographed right in the same general area. Also,
light-morph Harlan's make up only about 10% of the total of Harlan's hawks;
what kind of odds would put two light-morph Harlan's in the same
football-field sized area in western Oregon?
good birding, Tom

Hi Nancy and All,
I'm not convinced this is a Costa's Hummingbird. The color of the iridescence
just doesn't look violet enough to me, though digital cameras are notoriously
bad at getting that end of the spectrum correct. You can get multiple colors in
real life too, based on the nature of refracted light. But for a good Cost'as
I'd also expect the sides of the neck and the area above the cheek (beyond the
continuation of the little white supercilum) to be much paler.
One can spend hours analyzing a photo, yet it takes a fraction of a second to
analyze the utterly distinctive call note of Costa's Hummingbird. A question I
always have to ask when given mystery hummer photos is "what does it sound
like?"

Subject: [obol] Northern Polk County in the rain
POLK COUNTY—DEC. 7, 2019
Philippe Pessereau and I birded the Hwy 99 corridor in northern Polk County
today. Our first notable bird of the day was the Rough-legged Hawk. As
usual he was in the lone deciduous tree on the rise just south of Bethel
Road and along the east edge of the highway. The photo is execrable
because it was raining and the light was twilight dim.
We headed west from 99 along Smithfield Road. Almost immediately there
were sparrows, robins, birds out in the rain. At the first woods a
Steller’s Jay crossed the road. At one point Smithfield squeezed between
two overgrown hedges as we entered the first patch of the wildlife refuge.
There we saw a Fox Sparrow—a first of the year for me, a lifer for
Philippe. There were Song Sparrows, juncos, more robins—a veritable
flutter of bird life. A Mourning Dove sped past. We saw not a single
raincoat, no umbrellas either.
North on Livermore Road we walked onto the refuge land, unmarked. In one
impounded marsh with little water as yet we saw both Say’s and Black
Phoebe. This was east of the road. GW Teal, Mallards, sparrows and juncos
galore, Spotted Towhee, flicker and Bewick’s Wren—busy place.
About 1.5 miles north of Smithfield we checked out some ponds on private
land—not open to the public. Three river otters cavorting—another lifer
for Philippe as was the Say’s Phoebe. In that area we saw Gadwalls, flying
Snow Geese (about ten), kestrel and wet-tailed (red-tail) hawks, harrier,
also two blue herons. A meadowlark sang despite the drizzly day.
Back on Smithfield we found a field full of Killdeer with robins across the
road in the vineyards and trees along the road. A farm pond is next to the
road where the Van Duzer Vineyard lane goes uphill. There were pour first
Ring-necked Ducks of the day. Further south Smithfield climbs to the top
of a crest and we looked into the valley eastward where at least thirty
Tundra Swans swam in the lake on refuge land. Ducks there includes
shoveler, pintail, wigeon, g-w teal, Bufflehead.
Finally on Coville Road we stopped at the pond on the north side; many
dabblers, Cackling and Canada Geese, our close-up of a nutria. Poor
substitute for the speedy, playful otters. Along the Road we found two
damp meadowlarks, Bald Eagle, peregrine, more swans in the lake to the
north, long skeins of Cacklers across the sky.
Back at Hwy 99 we headed north and stopped to check the pond at Left Coast
Cellar (road not open until noon). Hooded Merganser flock included
breeding plumage males, many Bufflehead, another flock of ring-necks,
Mallards (of course), wigeon. While we were mudding around the scope along
the lane an adult Bald Eagle flew over. Good day had by birders and
waterfowl alike. Wet and cold, Philippe and I were smiling, amply
rewarded.
Our one worthwhile stop in Yamhill was the quarry pond on Fox Ridge Lane:
one Hooded Merganser, flock of Common, Buffleheads, a male Green-winged
Teal in among the divers.

Obol,
Although Peter Low had the bird with chickadees around the parking lot
late a.m., those of us arriving after noon only saw it around the trees
near the entrance area. You will see tracks in the snow concentrated
where groups of us watched the bird for periods. No telling if behavior
will be similar tomorrow, but this p.m. the best way to find it was by
finding Pygmy Nuthatches. Trees near and on both sides at the entrance
and even occasionally across OB Riley as far as the trees around the
KTVZ building and the sign for the state park office were used. We
watched it successfully obtain an insect from inside a pine cone. It was
mostly in junipers, other trees less.
Spread out and be in touch with each other if anyone finds Pygmy
Nuthatches. Earlier in the afternoon it was with a loose flock of mult
species, juncos, house Funches, etc.. Several times it foraged in a tree
long enough to allow good, almost prolonged looks.
Good luck with this first county record bird. Here is a shout out to
Peter Low for his skill and generosity, always sharing his finds. Judy,
