There has been considerable work done to compile fall migration dates for the Willamette Valley. Joel Geier and Alan McGie have been compiling data from 1983 through 2009.
Their work is presented below. However this is not a finished body of work. The authors note:
“It has not been sorted through as carefully as Alan’s compilation for the spring months. If you want to use these data on your website, that would be fine; you could call it “based on data from a draft compilation” so that people don’t get the idea that this is a fully edited product.”
I want to thank Joel and Alan for making this information available and for their dedication in compiling migration data for our ecoregion. They have truly enriched our understanding of avian movement through the Willamette Valley.
In the table below ‘N’ is the number of observation years.
