Key to symbols and colors used for bird arrival dates:

Typical arrival dates for the Corvallis area based on spring migrant phenology compiled by Alan McGie plus a fall migrant phenology (draft in progress) compiled by Alan McGie and Joel Geier.

Typical arrival dates for the Eugene/Springfield area based on spring migrant phenology compiled by Tom Mickel

Typical arrival dates for the Portland Metro area based on spring migrant phenology compiled by Christopher & Adrian Hinkle

† The terms "northbound" and "southbound" are used here as generalizations; many of Oregon's migrants have an east/west component and/or elevational component to their movements. The phenology for Willamette Valley locations includes arrivals of elevational migrants such as Varied Thrush.
