Bird Surveys

Counting on the Birds!

Throughout the year there are many organized bird counts in our region. The scope ranges from national to regional, and the format from defined protocols to whatever you can count. These surveys are examples of citizen science, a collaboration between scientific researchers and the general public. When you participate, you help provide data that will contribute to further understanding bird populations, their distribution, and any population changes. Two bird counts are held locally: the Christmas Bird Count (CBC) for the Corvallis area and the North American Migratory Bird Count (NAMC) which covers Benton County.

Christmas Bird Count

The Christmas Bird Count draws birders of all ages.

Audubon’s Christmas Bird Count (CBC) began in 1900, so 2018 was the 119th year! It is the longest running citizen-science survey in the world. Tens of thousands of volunteers throughout the Americas take part in the effort. Audubon and other organizations use data collected to assess the health of bird populations and to help guide conservation activities. To maintain accuracy, new volunteers join an established group with at least one experienced birdwatcher.

Corvallis: The first Corvallis CBC was held on December 26, 1912. The second count was delayed until 1962, and the CBC has been held every year since. The Corvallis CBC is traditionally held on the Tuesday before Christmas. This year’s Corvallis CBC is Tuesday, December 17, 2019.

Sign up in advance! Volunteers survey a specific portion of a 15-mile (24-km) diameter circle around Corvallis between December 14 and January 5, and send their results to the compiler. If you prefer, arrange to count birds at home feeders inside the circle on any day during the same period. Each count is for one day, and results are submitted to the compiler.
Contact Marcia Cutler for more information or to join the count.

Join us after the count for the traditional “count-down” and a potluck supper to share sightings and stories! A hot dish will be provided, but please bring a salad, dessert, bread and cheese, or some other dish to share, and your own eating utensils. The potluck will be held at Osborn Aquatic Center (940 NW Highland Dr, Corvallis) on Dec. 17th from 4:30-7 pm.
Contact Gail Nickerson for potluck information.

Other Bird Counts

    • Project Feeder Watch – Cornell Lab of Ornithology winter-long survey of birds that visit feeders in local areas. Send your count to Project FeederWatch to help scientists track long-term trends. Anyone interested in birds can participate.
    • Great Backyard Bird Count – The next count is Feb. 17 -20, 2020. More than 160,000 people of all ages join the four-day count to create an annual snapshot of the distribution and abundance of birds.
    • Oregon Black Oystercatcher Project – The goal is to provide new information about Oregon population estimates, nesting success, and human disturbance. The surveys are conducted on the North, Central, and South Coast from May to November.

The entire group is focused on one bird!

Participating in a birdathon is an excellent way to learn about migratory species, raise funds for environmental projects, add data to a national survey, and have fun. Since 2001, ASC has conducted Birdathons for the benefit of Hesthavn Nature Center. Combined earnings are about $80,000, which has funded a solar composting toilet, museum display cases, new flooring, weather-tight doors and windows, and other projects.

Form a team or go solo on the designated weekend, between April 1 and May 30, which ASC will announce early in the year. This is the peak migration period for birds in the U.S. If you have a conflict in dates, let the coordinator know, and select another weekend during the migration. Ask individuals or organizations to sponsor the team either per species or at a flat rate. Then, bird wherever you are – your backyard, the coast, the mountains, Costa Rica… the sky’s the limit (literally)!

If you own a local business, sponsoring a team or individual could generate good publicity. Or your business could sponsor every team at a certain rate. This encourages more people to participate, knowing they already have their first sponsor. Beyond raising funds for Hesthavn, more people may feel they have a personal stake in Hesthavn’s success and, more broadly, in wildlife and nature conservation.
