[obol] Around Washington County (04/05/08)

[Darrel Faxon]

Stefan,
    Looks Nelsonish to me, too, but one thing I find interesting about the bird are the wide white tips to the primaries.  As Dave Irons noted, this time of year gulls can show extreme abrasion on the wing feathers, some so extensively so as to give the appearance of completely lacking the outer edge.  However, the primaries on this bird do not appear to be so worn, and the white markings on the primary tips would be more typical for Thayer's than Herring.  I would not go so far as to actually suggest that might be the parentage of the bird.  I don't think anyone can ever be certain of such things on the basis of field characteristics, but it is an interesting option to consider.

  Michael Fleming from WA state, Mike "Art" Marsh and I toured selected sites around the county in the rain yesterday.
   
  We found Acorn Woodpeckers at the NE corner of Orenco Elementary School and on the southern edge of Dawson Ck Corparate Park in Hillsboro. 
   
  At Fernhill Wetlands, Barn and Cliff Swallows are back. A single male Common Yellowthroat must also just have arrived. The Great Horned Owl fledgling(s) seem to be in the nest, even though this was hard to see. The most interesting bird for me was a Nelson-ish Gull in the parking lot. I uploaded a couple of pictures on my blog at http://birdmeister.wordpress.com/. Feel free to comment.
   
  3 Eurasian Collared-Doves were at Porter & Verboort in Verboort.
   
  Killin Wetlands at around 6pm had 2-3 calling American Bitterns, Northern Rough-winged Swallows, another male Common Yellowthroat and several Cinnamon Teal.
   
  Finally, we managed to get a single calling Western Screech-Owl at Hagg Lake from across a clearcut just before it got dark about 1.4mi up Sain Creek Rd. My overall impression is that most owls have stopped calling. With the exception of Western Screech. On a pefect night last Tuesday, I had 2 calling birds at the Nelson Ck Rd turnoff, but nothing else.
