Observers

Weather         

-6 C with light pogonip falling as the morning fog drifted over Camp Baker.  The morning fog burned off quick with a daytime high of 7C and mostly south winds 3-11kph.  Later in the afternoon some cumulus clouds formed off to the east and threatened precipitation increasing until sunset.  The barometer fell steadily.

Raptor Notes 

(1) NG (1) LA (17) RT (1) UB (6) GE (1) UU

The flight started between 11:00-12:00 with 3 RTHA making their way past the OP.  It ended up being a strong showing of RTHA for the remainder of the day averaging 3 an hour.  By the end of the afternoon they were literally shooting through the valley.  It is amazing to see them make quick work of the distance considering how slow birds have moved through the area so far this season. 

Accipiters continue to increase, but many of them are distant and tracking a small raptor on a backdrop of forest miles away is difficult.  One exception was the immature NOGO that came very close to the OP from somewhere to the east.  The bird circled up the small forested knob to the south of the OP.  It didn’t climb this ridge like the resident raptors do, but instead shot into the Smith River Canyon.

Residents were active today just before the flight began to pick up.  I am generally getting more familiarized with their coming and going from the new OP as I can see more of where they originate from and seem to disappear towards.  The small forested knob to the SW of the OP is certainly a busy place for all species of resident raptor.  I wish I knew what was going on up there (to the west) as several times a day birds drop from Jumbo and other locations into this vicinity.  I have determined if they don’t appear to the west of the OP, climbing the ridge, then they must not be migrating.  This seems to hold true as the resident RTHA seem to frequent this area and will somehow reappear below the OP only to work their way back up to the forested knob.  I was worried later in the afternoon that the same may hold true for a pass far to the SW which seems to lead into some valley beyond the Dry Range.  Fortunately, I was able to watch several resident and migrant raptors disappear out of view to the west only to come back east to enter the canyon.  I feel pretty confident now that for the birds I am able to see to the south of the OP, if they are migrating, they will make it to the Smith River Canyon.  I have thought through many solutions to improving on the OP and one may be to move one ridge yet to the south of where I currently am counting from.  I have also thought of a couple vantage points further south as well, as by this point the birds may be more filtered onto one flight path and at the very least will definitely be obvious as migrants as there isn’t a large population of residents to sort through.

Non-raptor Notes


The new OP was surrounded several times by mixed foraging flocks of ORJU, WBNU, RBNU and MOCH.  This flock really livens up the afternoon with their chatter, especially the WBNU who seem to be the most vocal.  The ORJU like to forage right out on the rock face of the bluff.  Several flocks of SHCR came through.


89 antelope to the south west of the Johnston Ranch.  The resident chipmunk came and peered at my gear from behind a snowbank and RESQ are heard in the canyon to the west of the OP.
