I can add some information on the DC count from what Kurt and Fred reported.
If wintering populations of White-throated Sparrows appear healthy in rural
locations, they seem to be doing equally well in more urban areas as well.
When factoring out poor weather and a corresponding reduction in counters,
White-throated Sparrows in the DC count circle averaged between 1100 and
1300 individuals in the late 1990s and early 2000s and now average between
1600 and 1700 birds. We had over 2300 birds in 2012, establishing a new
count record.
Carolina Chickadees and Tufted Titmice fluctuate from year to year but show
no evidence of any declines. Chickadee counts range from 400 to 600 birds
and titmice somewhat less.
