County Birding Blitzes

36 Counties Complete!

Between 2014 and 2019, Oregon 2020 volunteers attended Birding Blitzes in all of Oregon's 36 counties.

Blitzes were by far our most popular and successful aspect of the project. Birders gathered in a single county to survey as many birds, in as many places, in just one weekend. The end result was impressive, state-wide coverage of Oregon 2020 Hotspots. You can see summaries from our past blitzes below, or check out our full project status here.

Birding Blitzes may be over, but you can still help the Oregon 2020 project in other ways! Click here to get involved.

Thanks to our many volunteers who made County Birding Blitzes a success!

How It Works

Similar to Christmas Bird Counts, participants cover assigned Hotspot Squares, usually 2-4 Hotspot Squares per day. We will provide you with materials and a quick tutorial of our counting methods. Each participant or team usually spends half the day counting birds in their assigned areas. In the afternoon, chase rarities and visit popular birding locations. Each evening we reconvene to share stories and highlights from the day.

Even better? Oregon2020 enters all your data for you. That’s right, count all the birds you can, we’ll take care of the rest! All the data are posted to eBird, shared with participants, and help fill gaps in our knowledge of Oregon’s birds.

There is no charge to participate in County Blitzes. However, participants are responsible for their own accommodations, meals, and travel arrangements (we often share a rental house). Feel free to participate in one or more days of each blitz. During registration you can inform us if you’d like to meet the night before (to get an early start), or have preferred birding areas.
