Oregon Birding Calendar

The purpose of this calendar is to list events that are of interest to Oregon's birding community. Birding events on the calendar are given as links that you can click on for more information. The calendar includes 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. Currently the calendar only shows this information for Willamette Valley locations (and only for the Corvallis area, in the case of "southbound" migrants). Information for other parts of Oregon will be added over time.

If you know of additional events that should be added to this calendar, please contact OFO's webmaster by e-mail (position currently vacant). Please include the name of the event, the date, and a web address or e-mail contact for further information.

Additional information for particular events

May 08 Fern Ridge Wings & Wine Festival:
Bird watchers, wine lovers, and nature enthusiasts are invited to the Fifth Annual Fern Ridge Wings and Wine Festival scheduled for Saturday, May 8, 2010 near Veneta, Oregon, west of Eugene. A wide array of activities will be held throughout the day at Domaine Meriwether's new winery and nearby Fern Ridge Reservoir, one of Oregon's best birding areas. The day's schedule includes bird and nature walks, hands-on workshops, canoe trips, educational talks, children's activities, and a wine-tasting/bird-watching bus tour. Many activities are free, but some require pre-registration and a fee. Click here to visit the Wings and Wine Festival website for more information.

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.
