When to put out oriole feeders in Oregon

The Oregon oriole season
Bullock's Orioles favor Oregon's dry side — the oak savannas of the Rogue Valley and the cottonwood rivers east of the Cascades. They're scarcer in the wet Willamette lowlands, so Portland-area sightings cluster along the Columbia. Arrival runs late April in the south to mid-May up north.
Two oriole quirks are worth planning around. First, arrival day matters more than with any other feeder bird — orioles choose territories within days of landing, so a feeder that's already stocked can anchor a pair all summer. Second, the season ends early: oriole migration starts in mid-summer, not fall, so don't mistake the August quiet for a mistake on your part.

The oriole menu: grape jelly, orange halves, and 6:1 nectar — a weaker mix than hummingbirds get.
Feeding guide Nectar calculatorFrequently asked questions
When should I put out oriole feeders in Oregon?
Have jelly, orange halves, and nectar out by April 20 — about two weeks before the first birds typically arrive (late April to mid-May). Orioles decide on a yard within days of arriving; a feeder that's already waiting often earns a resident pair for the season.
When do orioles leave Oregon?
Earlier than most people expect — early September. Orchard Orioles start south as early as July, and adult males of every species leave ahead of the young. Keep feeders up until late september for the stragglers, and remember: a feeder never delays migration, which is triggered by day length.
Why did my orioles stop coming to the jelly in June?
They didn't leave — they changed jobs. While raising nestlings, orioles switch almost entirely to insects for protein and largely ignore jelly and nectar. Keep a modest amount available, and expect a noisy second rush in July when the fledged families return to sweet foods before migration.
What should I feed orioles?
Three things work: grape jelly in a small open dish (a spoonful at a time — it should be a treat, not a meal), fresh orange halves on a spike or rail, and sugar-water nectar mixed 6 parts water to 1 part plain white sugar — weaker than hummingbird mix. Skip anything dyed, and pull jelly in high heat when it gets sticky enough to foul feathers.
