[obol] Lincoln Sparrow Clackamas Cnty.

[Al Ahlgrim]

A LINCOLN SPARROW took a prolong splash in our bird-bath on Monday afternoon south of Oregon City at an elevation of about 450'.  I noticed two sizable white blotches on the sparrow's tail near it's rump which I initially took to be bird droppings.  After the sparrow washed, fluffed up and flew away I checked the bath and found that the white material which had been stuck to the bird was lichen.  We have not seen a Lincoln Sparrow in or within miles of our yard in the past 20+ years and I suspect that if it hadn't needed a clean up, we still wouldn't have seen one here.
