Ever since I began spending a significant amount of time birding about 5
years ago, I have been curious about the differences in spring and fall
migration. Here are the percentage of warbler species I have seen from
2008-2010 during the spring and fall seasons excluding Yellow, Redstart,
and Yellowthroat. These numbers are mainly from Carver County but also
include some observations made in the Eden Prairie area.
