Hummingbirds in Portland, Oregon: A Complete Guide to Species and Seasons

Portland’s lush Pacific Northwest environment creates the perfect stage for one of nature’s most spectacular performances.

While most of the country waves goodbye to their tiny, jewel-toned visitors each fall, Portland residents get to witness something truly special—year-round hummingbird activity that transforms backyard feeders into bustling airports of iridescent wings and territorial disputes.

Whether you’re a seasoned birder or someone who’s just noticed these aerial acrobats zipping through your garden, Portland offers an incredible opportunity to observe multiple hummingbird species throughout the year.

From the feisty Anna’s hummingbird that braves Oregon’s winter rains to the aggressive Rufous hummingbird that arrives each spring ready to claim its territory, these remarkable creatures bring constant entertainment to anyone willing to look up.

This guide will help you identify the five hummingbird species that call Portland home, understand their unique behaviors and seasonal patterns, and discover how to create an irresistible hummingbird haven in your own backyard.

Anna’s Hummingbird – Portland’s Year-Round Resident

Anna’s Hummingbirds are the only hummingbirds to stay in Oregon year-round, bringing a dash of bright pink to our wet winters. These medium-sized hummingbirds have adapted remarkably well to Portland’s climate, making them the backbone of the city’s hummingbird population.

Physical Characteristics

Anna’s Hummingbirds are mostly green and gray, without any rufous or orange marks on the body. The male’s head and throat are covered in iridescent reddish-pink feathers that can look dull brown or gray without direct sunlight. The Anna’s habitat extends from Alaska to Mexico at this point. It’s a medium-size hummingbird with a gray and green hue. The males have a distinctive pink-red patch in a spot called a gorget under their beaks; the bright color also extends over their heads.

Female Anna’s hummingbirds lack the vibrant gorget but display beautiful green backs and grayish-white undersides with small green spots along their sides. Both sexes measure about 4 inches long with a wingspan of roughly 5.25 inches.

Behavior and Habitat Preferences

Anna’s hummingbirds exhibit fascinating winter adaptations that set them apart from their migratory cousins. They enter a state called torpor during cold nights, lowering their body temperature and heart rate to conserve energy. This remarkable physiological adjustment allows them to survive Portland’s chilly winters when flower nectar becomes scarce.

Did You Know? Anna’s hummingbirds can remember the location of individual flowers and feeders for up to a year, often returning to the exact same spots season after season.

These year-round residents prefer:

• Urban and suburban gardens with diverse flowering plants
• Areas with both nectar sources and small insects for protein
• Locations near water sources like fountains, sprinklers, or bird baths
• Spots with perching opportunities on thin branches or wires

The Portland Audubon Society recommends planting native species like red-flowering currant, which blooms early in the season when Anna’s hummingbirds need the most energy support.

Rufous Hummingbird – The Feisty Spring Arrival

The Rufous Hummingbird is a tough little customer. They’re known for being very aggressive and territorial, sometimes fighting with birds over twice their size. These small but mighty birds arrive in Portland around mid-March and quickly establish themselves as the bullies of the hummingbird world.

Migration Patterns and Timing

Rufous hummingbirds undertake one of the most impressive migrations in the bird world relative to their size. Has one of the longest migratory routes of any bird. Travels 3900 miles between Alaska and Mexico twice a year. They typically arrive in Portland between mid-March and early April, with males arriving first to establish territories.

Identifying Rufous Hummingbirds

Male Rufous hummingbirds are unmistakable with their brilliant orange-red plumage that seems to glow in sunlight. Females present more of an identification challenge, showing green backs with rufous sides and distinctive rufous patches at the base of their tail feathers.

Territorial Behavior

Rufous hummingbirds don’t just defend their feeding territories—they dominate them. These tiny warriors will chase away birds many times their size, including woodpeckers, jays, and even small hawks. They’re particularly aggressive toward other hummingbirds, often monopolizing entire feeders or flower patches.

Management Strategy: If you’re dealing with one overly aggressive Rufous hummingbird, try placing multiple feeders around your yard, ideally out of sight from each other. This prevents a single bird from guarding all food sources.

Black-chinned Hummingbird – The Subtle Visitor

Black-chinned hummingbirds represent the more understated members of Portland’s hummingbird community. While less common than Anna’s and Rufous species, they appear regularly enough during warmer months to warrant attention from dedicated birders.

Seasonal Presence

These hummingbirds typically arrive in Portland in late April or early May, staying through August before beginning their southward migration. They’re most commonly spotted in:

• Riparian areas along the Willamette River
• Parks with diverse flowering plants
• Residential areas with mature gardens
• Areas transitioning between urban and natural habitats

Distinguishing Features

Black-chinned hummingbirds can be challenging to identify, especially females and juveniles. Males display a distinctive black throat with a thin purple band at the bottom, visible only in proper lighting. Their backs show metallic green coloring, while their sides remain grayish-white.

Females lack the dramatic throat coloring but can be identified by their clean white underparts and subtle green backs. They’re slightly smaller than Anna’s hummingbirds and show less territorial aggression than Rufous species.

Attracting Black-chinned Hummingbirds

The Dennis’ 7 Dees garden center suggests these approaches for attracting this species:

• Plant native monarda (bee balm) and cardinal flower
• Maintain feeders with fresh nectar throughout summer
• Provide water sources with gentle movement
• Create vertical habitat layers with shrubs and trees

Mini Q&A: Why are Black-chinned hummingbirds less aggressive? Unlike Rufous hummingbirds, Black-chinned species have evolved in environments with more predictable food sources, reducing the evolutionary pressure for extreme territorial behavior.

Calliope Hummingbird – The Rare Spring Migrant

Portland birders consider Calliope hummingbird sightings a special treat. As North America’s smallest bird, these tiny gems occasionally pass through Portland during spring migration, typically in May.

Physical Characteristics

Calliope hummingbirds are truly miniature, measuring only 3.25 inches long with a wingspan of 4.25 inches. Males sport distinctive streaked purple throat feathers that extend like rays from their chin, quite different from the solid gorgets of other species.

Where to Spot Them

Calliope hummingbirds prefer:

• Mountain meadows and forest edges
• Areas with willow, alder, and cottonwood trees
• Locations near streams or water sources
• Residential areas with diverse, native plantings

The Cornell Lab of Ornithology notes that these birds often forage at lower heights than other hummingbird species, making them easier to observe when present.

Migration Timing

Calliope hummingbirds follow a unique migration pattern, moving north through interior valleys and returning south along the coast. Portland sits at the intersection of these routes, creating occasional opportunities for spring sightings between late April and mid-May.

Costa’s Hummingbird – The Unexpected Winter Visitor

Costa’s hummingbirds represent one of Portland’s most surprising hummingbird visitors. These desert-adapted birds occasionally show up in Portland during late fall and winter, creating excitement among local birders.

Identification Challenges

Costa’s hummingbirds can be easily confused with Anna’s hummingbirds, particularly females and juveniles. Males display a distinctive violet-purple gorget that extends well beyond their throat, creating a dramatic “mustache” effect. Their backs show gray-green coloring rather than the bright green of Anna’s species.

Why They Visit Portland

Climate change and habitat modifications have expanded Costa’s hummingbird range northward. These vagrant visitors likely arrive in Portland through:

• Following warm air currents during unusual weather patterns
• Expanding their range as temperatures moderate
• Following food sources during drought conditions in their typical range

Did You Know? Costa’s hummingbirds are adapted to desert conditions and can survive on less water than other hummingbird species, making them surprisingly resilient winter visitors.

Understanding Hummingbird Season in Portland

Portland’s unique geographic position creates an extended hummingbird season that spans the entire year, with distinct peaks of activity coinciding with migration periods.

Year-Round Activity Calendar

Winter (December-February)

• Anna’s hummingbirds remain active throughout
• Occasional Costa’s hummingbird reports
• Lowest flower availability requires feeder maintenance
• Torpor behavior most common during cold snaps

Spring (March-May)

• Rufous hummingbirds arrive mid-March
• Peak migration activity in April
• Black-chinned hummingbirds appear in May
• Calliope hummingbirds possible during late May

Summer (June-August)

• All species present and active
• Peak breeding season for residents
• Highest territorial aggression
• Abundant natural food sources

Fall (September-November)

• Migratory species begin departure
• Rufous hummingbirds leave by October
• Anna’s hummingbirds become more visible
• Preparation for winter feeding important

Migration Timing Specifics

Consider putting your hummingbird feeders out in late February to early March in Oregon. However, if you live in western Oregon you may want to consider leaving your feeders out all year as Anna’s hummingbirds are year round residents in this part of the state.

The Oregon Department of Fish and Wildlife recommends maintaining feeders year-round in the Portland area to support both resident Anna’s hummingbirds and early spring migrants.

Attracting Hummingbirds to Your Portland Backyard

Creating a hummingbird-friendly environment in Portland requires understanding both the birds’ needs and the city’s unique growing conditions. Success depends on combining proper feeding techniques with strategic landscaping choices.

Essential Feeding Guidelines

Nectar Recipe and Safety The number one most important thing to remember for feeding the hummingbirds of Oregon is to never fill your feeders with the red-dyed nectar mix so commonly found for sale in stores. The petroleum-based Red #40 can be harmful to the health of these little feathered buddies.

Safe Homemade Nectar Recipe:

• 1 part white granulated sugar
• 4 parts water
• Boil water, dissolve sugar, cool completely
• No red dye, honey, or artificial sweeteners

Strategic Feeder Placement

Multiple Feeder Strategy Given the territorial nature of Rufous hummingbirds, successful Portland hummingbird feeding requires strategic planning:

• Place feeders out of sight from each other
• Position feeders 10-15 feet apart minimum
• Use different feeder styles to accommodate various preferences
• Maintain fresh nectar every 3-5 days (more frequently in hot weather)

Winter Feeding Considerations If the weather is really cold, bring your feeder in at night. Don’t forget to put it back out in the morning when hummingbirds are at their most active and hungriest.

Portland-Specific Plant Recommendations

Native Plants for Year-Round Interest

• Red-flowering currant (Ribes sanguineum) – Blooms February-April
• Oregon grape (Mahonia aquifolium) – Early spring nectar
• Salmonberry (Rubus spectabilis) – Spring flowers
• Madrone (Arbutus menziesii) – Late spring blooms

Non-Native Hummingbird Magnets

• Bee balm (Monarda) – Summer-long blooms
• Cardinal flower (Lobelia cardinalis) – Late summer color
• Fuchsia – Continuous blooms in Portland’s climate
• Trumpet vine (Campsis radicans) – Late summer attraction

Water Features and Habitat

Hummingbirds need to consume one-third to one-half of their body weight in nectar every day to keep up with their incredibly rapid metabolisms. Beyond nectar, they require:

• Water sources: Shallow dishes, misters, or fountains
• Perching spots: Thin branches or wires near feeders
• Nesting materials: Small twigs, moss, and spider webs
• Insect habitat: Hummingbirds need protein from small insects

Pro Tip: Install a small water feature with gentle movement. The sound of dripping or flowing water attracts hummingbirds from surprising distances.

Seasonal Care and Maintenance

Spring Preparation (February-March)

Feeder Readiness Hummingbirds may arrive in your area before they are marked on the map, so get your feeders ready about two weeks before their anticipated arrival date. Put out feeders early to catch the first migrating hummingbirds.

Tasks for Early Spring:

• Clean and inspect feeders for winter damage
• Prepare fresh nectar recipe ingredients
• Prune flowering plants to encourage spring blooms
• Check water features for winter damage

Summer Peak Management (June-August)

During Portland’s peak hummingbird season, maintenance becomes critical:

Weekly Tasks:

• Change nectar every 3-5 days (daily in temperatures above 85°F)
• Clean feeders with hot water and vinegar solution
• Monitor for ant problems and install ant moats if needed
• Deadhead flowering plants to encourage continued blooming

Monthly Tasks:

• Deep clean feeders with diluted bleach solution
• Evaluate feeder locations for traffic patterns
• Plant late-summer blooming species
• Monitor for signs of sick or injured birds

Fall Transition (September-November)

As migratory species prepare for departure, feeding strategies should adapt:

Continued Support:

• Maintain feeders through October for late migrants
• Plant late-blooming native species
• Avoid aggressive feeder cleaning (birds need steady food sources)
• Begin transitioning to winter-only feeding approach

Winter Care (December-February)

Winter hummingbird care in Portland requires special attention to weather conditions:

Cold Weather Protocols:

• Bring feeders in during freezing temperatures
• Use feeder heaters or wrap feeders in insulation
• Place feeders in sheltered locations
• Monitor Anna’s hummingbirds for signs of stress

Equipment for Winter Feeding:

• Insulated feeder covers
• Heated bases for extreme cold
• Wind protection shields
• Quick-access feeder designs for easy winter maintenance

Common Challenges and Solutions

Dealing with Aggressive Territorial Behavior

Problem: One Rufous hummingbird dominates all feeders Solution: Create multiple feeding stations beyond the sight lines of aggressive birds. Use different feeder styles and heights to accommodate various preferences.

Maintaining Clean Feeders

Problem: Nectar spoilage and mold growth Solution: Your hummingbird feeder will be a supplemental source of nectar for your local hummingbirds, and can help them through times when there aren’t as many blooming flowers available. Clean feeders every 3-5 days with hot water and white vinegar.

Ant and Wasp Problems

Problem: Insects interfering with hummingbird feeding Solution: Install ant moats above feeders and choose feeder designs with built-in bee guards. Position feeders away from ant trails and sweet-smelling plants.

Window Strikes

Problem: Hummingbirds colliding with windows near feeders Solution: Place feeders either very close to windows (less than 3 feet) or far away (more than 30 feet). Install window decals or screens to increase visibility.
