I believe what Michael is referring to in this species is a move west. This species is increasily creeping into areas such as New Mexico and is almost annual to uncommon in eastern parts of that state and I'm sure similar situations exist for this species.

Actually, unless something has changed, Carolina wrens tend
to be "tidal" -- they've historically been fairly common in
parts of New York and New England after relatively mild winters,
and quite scarce or absent after harsh winters. If there
hasn't been a harsh winter -- I don't know whether this is defined
primarily by temperature or snow cover -- for the last several
years, it could seem like any other range expansion. Of course it
*is* a range expansion, but it might be just temporary, as has
been the pattern.

if you are going with Eastern birds, you scan also
