Weather         

Foggy to the north and east this morning with a temperature of-7C.  Winds were out of the south until 13:30 when the winds switched, gusting out of the north 7-27kph average.  Conditions were excellent for viewing raptors with a nice cloud cover of mostly fog, cumulus and stratus clouds moving in a variety of directions.  This shift in winds kept the daytime high to 6C and things cooled down steadily to 2C by the end of the count at 17:00.  Visibility came and went to the east today with only the hills just past the Smith River Road to the east visible at times.  If anything, this funneled all of the birds nearer the OP.  24cm of snow remain today at the end of the count.  The Smith River was running at the end of the count today from upstream of the Johnston Bridge to just below the lower boat ramp.  The entrance to the canyon is still iced in as well as Sheep Creek isn’t flowing yet either.  This happened quickly as at 13:30 things were frozen over again.

Raptor Notes

17 migrating raptors flew north today to the Smith River Canyon.  BAEA (9) led the flight with a kettle forming directly over the OP between 13:00-14:00.  It was difficult to determine who was resident and who was migrant at times, but the number of non-adult birds made it a little easier (as it has been primarily adult BAEA escorting migrants from the area).  Several of these birds seemed to be harassing each other and there were lots of calling as they moved higher above the OP before proceeding north into the canyon.

(1) RLHA and the first (1) NOHA of the season also mixed in with the eagles, but staying well away from the skirmishes.  (2) GOEA came through as well.  It is possible, they may have been following a different flight path than the BAEA today and I may have missed some while tracking the BAEA.

Migrants flew a variety of different flight paths today with some passing to the east of the OP on the near rise between Sheep Creek and the Smith River.  Others like the kettle of BAEA came off of Jumbo, crossed in front of the OP then kettled again off of the butte to the west of the OP.  I felt by the end of the day I could almost feel the birds beginning to stack up as it was a wall of fog waiting for them to the north in the canyon and a pretty stiff north wind.  Today’s flight had to provide some of the most memorable up-close looks at passing BAEA as many of them just kited in place or came down the rise only to break off to the east or west to repeat the process.  It was exciting to have that many large raptors that close streaming in off of Jumbo.

Residents were busy escorting migrants today and the adult BAEA definitely had its territory run over with non-adult migrants.  It appears possibly an S2 BAEA is now setting up a territory in the area as it was actually chasing one of the resident adults.  This bird was observed regularly throughout the day making use of Jumbo and the canyon without sustaining any skirmishes from the earlier residents.

The adult light-morphed RTHA is pure fire these days stooping at CORA and AMCR throughout the day.  Many of the resident ranch birds are now realizing the shortcut through the hills from Sheep Creek to Smith River is directly in the line of fire.  Another resident RTHA ventured into this zone and was shut down immediately only to abandoned course and return upstream.  The hill that this RTHA seems to be fond of would be my first consideration for an owl decoy in future years.  I have an excellent view of the hill from the OP and it is a partially dead tree.  The decoy would be directly in the line of fire for all migrating raptors coming off of Jumbo.  I have an idea of another spot closer for a near owl decoy as well.  Of course, this would have to be hammered out with willing land owners as both locations are on private property.

A resident MERL returned giving the MOBL a good chase from time to time.  It was exciting to see this powerful falcon flying directly into stiff north winds with no problem whatsoever.  Based on its repeated strafing runs of the near rise to the east of the OP I don’t believe this is the last time I will be seeing this small terror.

Non-raptor Notes

Mountain Bluebird

SACR, COME, MOBL and RWBL are all increasing in numbers at Camp Baker.  The RBGU that was noted flying back south a few days ago over the Smith River Road mixed into a kettle of BAEA at one point.

Visitors
