Is the discussion concerning Mistletoe, a parasitic plant on Oaks, or Holly
which has red berries that may species of birds ingest?

Western Bluebird numbers are spiking because of widespread snow on upland
sites right now. The I-5 corridor is blissfully free of that snow. I believe
Westerns are migrating in nw Oregon at this time and have been shunted
downslope. I was marveling today at the solid historic absence of bluebirds
on Sauvie lsland, where habitat structure looks great. Likewise they are
absent from lowlands of Tualatin Valley. I saw them in the Chehalem Hills
this time of year when l did a raptor survey there. I have seen them
migrating and nesting in clearcuts near Hayward.
Why the mistletoe stops where it does? I would expect it to be
dispersed by birds. All manner of thrushes eat its fruit. Its northern limit
in Yamhill County is abrupt.

A friend just reported seeing a flock of bluebirds in Eugene where he'd
never seen any close by. Is it my imagination, or are there a higher
than normal number of Western Bluebird and vagrant Mountain and Eastern
bluebird reports in the Willamette Valley?
