      3 December 2007 - Some of you may recall my last posting about the
      Mendocino County Bird Records Committee and earlier results of a few
      observation reviews. The MCBRC, a committee of six local
      experienced birders, are in the process of reviewing some of the old
      observation records and some current
      observation records from Mendocino County. It takes either an
      "Aye:Nay" ratio vote of 5 to 1 or 6 to 0 to be ACCEPTED. The
      committee has recently reviewed 12 records and will continue to work
      on other record reviews over the next few years. Here are the
      results of the last reviews:

      Observations voted as ACCEPTED:

      been on Lake Mendocino for
      some prior time but had been mis-identified by

      Review2007#14 Blue-winged Teal 17 Jan 1993 DTobkin
      2m Garcia River Flats ACCEPT 6:0 stands as second & third
      county record

      Review2007#16 Fulvous Whistling Duck 8 Dec
      1962 JRArnold 7 Lake Cleone ACCEPT
      6:0 stands as 1st through 7th county record
      this was a long-standing record that was
      questionable until recently discovered information about the
      observer. John (Jack) R. Arnold was an
      ornithology professor at Sonoma State College, had a
      MS degree from Cornell University, grew up and taught high school in
      the San Joaquin in
      era when Fulvous Whistling Ducks were occasionally
      found there, seriously birded the North Coast with Mike Parmeter for
      decades, and knew
      that the observation was rare enough to publish it
      in Condor, Vol.65, p 442. The birds were seen over a period of days
      by at least two other
      observers who were both Calif. state park
      rangers. All this gave substantial credence to the records despite
      the lack of detailed characteristic
      notes.

      Observations voted as NOT ACCEPTED:

      Review 2007#8 Tufted Duck 23 Jan
      1997 GChaniot,DAE 1f Potter Valley NOT ACCEPT
      3:3 this was most probably a
      female Tufted Duck, but Nay votes were based upon
      observer's uncertainty at time of observation, could not rule out
      Lesser Scaup female
      Review2007#15 Black-capped Chickadee 29 Sept
      2007 LSiemens 1 Manchester NOT ACCEPT 1:5 Nay
      voters felt that Mountain
      Chickadee could not be ruled out, plus were
      concerned with brevity of observation, observation outside of known
      species range (Ferndale,
      Humboldt County is the southernmost extension of the
      known range), outside of normal habitat for North Coast (willows),
      and description lacked
      a couple key characteristics for Black-capped Chickadee.

      Observations - RETRACTED

      Review2007#12 Long-tailed Duck 27 Sept
      1993 RKeiffer ,ETurula,S.Cardwell 2f Glass
      Beach,Ft.Bragg RETRACTED this was first
      submitted for review from the old archived data base
      (PLOVER). Further checking with the observers clarified that this
      had been mis-entered into
      the data base and was really two female Harlequin Ducks seen
      ...not Long-tailed Ducks.

      I would like to extend thanks to all who send in and report Mendocino
      County bird observations (Mendobirds or otherwise). All of these
      records build an important data base of bird species use in Mendocino
      County and may help to reveal change of use, change of habitat, loss
      of habitat, etc. over time. If an observation is reviewed, either by
      the California BRC or the Mendocino County BRC, a "NOT ACCEPT" record
      is just as important as an "ACCEPT" record...and all are archived for
      future reference.

      Good birding. Bob Keiffer
