Winter Birds in Oregon 2026: Top Backyard Birds

Q: What birds are at feeders in Oregon in winter?

The perching birds, woodpeckers and doves reported most in Oregon in winter are the Dark-eyed Junco (3.5%), Song Sparrow (2.3%), American Robin (2.2%), Golden-crowned Sparrow (2.0%) and California Scrub-Jay (2.0%). Each figure is that bird's share of all research grade winter bird reports for the state on iNaturalist, December to February across the ten winters from 2016-17 to 2025-26.

Q: Which birds come to Oregon only for the winter?

In the Oregon record the winter visitors are the Golden-crowned Sparrow, Bufflehead, American Wigeon, Varied Thrush, Ruby-crowned Kinglet and Ring-necked Duck. Each makes up at least 10 times the share of winter bird reports that it does in summer, so it is a bird that arrives with the cold and leaves in spring.

Q: What is the most reported winter bird in Oregon?

The Dark-eyed Junco, with 3.5% of all research grade winter bird reports for Oregon (3,280 reports over ten winters). The Song Sparrow is next among the feeder birds at 2.3%.

Q: When is the Christmas Bird Count in Oregon?

The Christmas Bird Count runs from December 14 to January 5 every year in Oregon and across the country. Each local count covers a circle 15 miles wide on a single day in that window, and anyone living inside a circle can join as a feeder counter from home.

Q: How can someone in Oregon count birds from home this winter?

Project FeederWatch runs from November 1 to April 30 and asks for counts on two consecutive days as often as once a week. The Great Backyard Bird Count takes as little as 15 minutes on one of four days in February, with February 12 to 15 posted for 2027.

Q: How often should a bird feeder be cleaned in Oregon?

The Cornell Lab of Ornithology recommends cleaning seed and suet feeders every week or two, and more often in heavy use or wet weather, then soaking the parts for 10 minutes in one part bleach to nine parts water. Fluffed up feathers, lethargy and crusty eyes are signs of illness.

Q: How are the Oregon winter bird numbers counted?

Every figure is a count of research grade bird observations uploaded to iNaturalist for Oregon, December to February across the ten winters from 2016-17 to 2025-26, divided by all research grade bird observations for the state in the same months. The same shares for June to August separate the winter visitors from the year round birds.

Feeding birds in winter

Cleaning

“Clean your seed or suet feeders regularly (e.g., every week or two) and more often during periods of heavy use or wet weather.”
Cornell Lab of Ornithology, Project FeederWatch

“Debris (such as leftover bits of seeds and hulls) can harbor pathogens that make birds sick.”
Cornell Lab of Ornithology, Project FeederWatch

Disinfecting

“To disinfect your feeders, soak the (cleaned) parts for 10 minutes in a diluted bleach solution (e.g., one part bleach to nine parts water).”
Cornell Lab of Ornithology, Project FeederWatch

Sick birds

“Fluffed-up feathers, lethargy, abnormal growths, and crusty eyes are all symptoms of various avian illnesses.”
Cornell Lab of Ornithology, Project FeederWatch

House finches

“For example, not every bird that is exposed to Mycoplasma gallisepticum will contract conjunctivitis; however, House Finches are especially susceptible to this bacterium, which led to serious declines in North American populations in the 1990s.”
Cornell Lab of Ornithology, Project FeederWatch

Bird flu

“Bird feeders are unlikely to result in increased spread of avian influenza since the species of bird that tend to come to feeders are not commonly infected.”
U.S. Fish and Wildlife Service

“However, feeders do concentrate passerines and increase the risk of transmission of other infectious diseases that do impact their health, including salmonella, E. coli and mycoplasma.”
U.S. Fish and Wildlife Service

Planting

“Creating natural spaces that attract birds to the cover and food provided by native vegetation appropriate to the location is far healthier than feeders.”
U.S. Fish and Wildlife Service

House finches are the feeder bird most prone to the eye disease Cornell describes above, so crusty or swollen eyes on one are a signal to clean. “Watchful House Finch at feeder (26735005435)”, David Whelan, CC0
