Western Oregon Birding Calendar

This calendar gives information on migrant phenology, to give an indication of when to look for bird species to arrive. Typical "fall" or "southbound" arrival (↓) dates and "spring" or "northbound" arrival (↑) dates are indicated by bird species names and arrow symbols in different colors, as explained in the key at the bottom of the calendar.

Key to symbols and colors used for bird arrival dates:

↑[species name] indicates "spring" arrivals of species that either nest in Oregon or continue northward.†
↓[species name] indicates "fall" arrivals of species that either winter in Oregon or continue southward.†
®[species name] indicates selected rarities (with year of occurrence in parentheses). Note that dates may not correspond eactly in the case of leap-year records, as this calendar is based on day numbers (number of days from Jan 1) in each year.

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.
