**rare; very gray female identified as S. m. borealis; grayish head, pale grayish-buff breast and upperparts; the paler back and scapulars made; fresh even-age wing coverts indicate an after hatch-year (fide Jessie Barry). Other than the starkly grayish coloration, there was little else to distinguish from the surrounding S. m. dresseri, but on close examination the bill was: 1) slightly shorter (maybe 75-85% the length of bills of nearby dresseri); 2) bill processes were similarly shorter; 3) had possibly very slightly more pointed bill process; 4) had an odd grayish blob just proximal to the tip, though this was possibly not significant; 5) may have had a slightly different nostril position relative to the dresseri (nostril a bit more proximal relative to the central lobe of feathering). The nail was prominent and hooked (but this seemed variable). If photo review confirms these characters we will change this record to S. m. borealis.
