No consistent directional trend in coastal Lane, just loads of birds and using
unusual habitats. I suspect that forest fires are a factor for these birds,
but that’s just speculation.
My understanding is that the Boreals in far NE Washington are extremely rooted
and don’t irrupt. However, if I understand Matt’s point correctly, there is
also the question of whether relict populations could exist in places like the
Wallowas without being noticed, which was true of Boreowl. I think they could,
though it is not likely. One reason why this could happen with Boreal
Chickadee is that they are remarkably shy for a parid. The ones I saw in
Vermont and Alaska did NOT want to be seen and were about as cooperative as a
cuckoo - not. They are very sneaky and quiet.

Where did the Chestnut-backed Chickadees come from that were racing down the
Oregon Coast? Chestnut-backed Chickadees are a normal part of our coastal
avifauna, so seeing that species along the coast is not a big deal, but Alan
and I (others?) clearly noticed bands of *traveling* birds, from north to
south
I know Matt saw a large flock flying south on the coast, but for what it's
worth the concentrations I saw at
Cascade Head on both 9/19 and 10/3 were clearly
moving north. Also I don't think Alan commented on
a directional trend in his south coast report.
This at least suggests the possibility the coastal Chestnut-backed numbers
and wandering southbound Mountain Chickadees may be causally unrelated.
