Subject: [BIRDCHAT] Boreal Finches - Superflight 2007-2008
Date: Wed, 7 Nov 2007 23:16:52 +0000
We are experiencing the biggest winter finch irruption since the
"superflight" of 1997-1998, when many boreal finches went well beyond their
normal ranges. The cause is the largest tree seed crop failure in a decade
across more than 3200 km (2000 mi) of boreal forest from Saskatchewan into
Quebec. Today in Toronto, I had a Pine Grosbeak, Evening Grosbeaks, Common
Redpolls, Pine Siskins and Purple Finches migrating along the shoreline of
Lake Ontario. Boreal winter finches are being reported in many areas of
southern Ontario and the United States, where some species such as Pine and
Evening Grosbeaks haven't been seen in years. There is no telling how far
south this "superflight" will go.
