      Robin Migration Enthusiasts:

      Just a quick report of the continued American Robin migration at the Marin
      Headlands just north ofthe Golden Gate Bridge:

      Friday, November 23: 7-11:30 am
      Sunday: November 25: 7-10:30 am (different observation point that did not have
      trees so finch numbers were lower than the

      usual observation spot)

      American Robin 7588* 2336
      Varied Thrush 135-387** 259 (10% of all observed thrushes)
      Band-tailed Pigeon 1750 756
      Yellow-rumped Warbler 166 10
      Purple Finch 131 45
      Cedar Waxwing 449 120
      American Pipit 5
      House Finch 31 5
      Lesser Goldfinch 13 10
      Pine Siskin 13
      Starling 168 160

      * over 3300 between 7-8 on 11/23
      ** probably 5% of all thrushes

      It appeared that most thrushes and pigeons were not migrating over the
      Golden Gate Bridge but heading east towards Contra Costa and Alameda
      Counties.

      Totals for four days of observation in November (Nov 3, 4, 23, and 25):

      American Robin 16748
      Varied Thrush ~3972
      Cedar Waxwing 2294
      Band-tailed Pigeon 4381

      Good birding to you......
