Townsend's Warbler is one of the shorter-distance migrants showing an
increasing willingness to overwinter in larger numbers in northern
California, Oregon, and Washington. Especially the former two so far, but I
certainly expect them to increase in winter here as well. I've got some
graphs of these trends here (Townsend's Warbler is near the bottom):

In a few months, eBird will be releasing detailed trend maps for 451
species, which will really tell us a lot more about recent shifting range
patterns in a time of rapid climate change. Some glimpses of eBird's maps
were shared at the Wash Ornith Soc (WOS) mtg a few months ago.

good birding,
