You’ll discover when to expect their arrival, what they need to thrive, and how to create the perfect habitat that keeps them coming back year after year.
Ruby-throated Hummingbird

The ruby-throated hummingbird stands as Pennsylvania’s only regularly breeding hummingbird species, making it the most familiar and cherished of all backyard hummingbirds Pennsylvania residents encounter. These remarkable birds serve as the foundation of Pennsylvania’s hummingbird population, with their distinctive characteristics and behaviors defining the hummingbird experience for most Pennsylvanians.
Physical Characteristics and Identification
Ruby-throated hummingbirds are nature’s living jewels, measuring just 3 to 4 inches in length with a wingspan of 4.5 inches. Males display an unmistakable iridescent ruby-red throat patch that appears to shift from black to brilliant red depending on the light angle. Their backs shimmer with metallic green, while their bellies remain a clean white. Females lack the red throat patch but showcase the same emerald green back with a white breast, often featuring small gray spots.
The sexual dimorphism extends beyond coloration. Males typically arrive in Pennsylvania several weeks before females during spring migration, establishing territories and competing for prime feeding locations. This early arrival strategy helps ensure successful breeding opportunities when females finally reach their breeding grounds.
Breeding Behavior and Habitat Preferences
Most breeding occurs in late May and June, but second broods may occur into July. Individual males may mate with several females. This polygamous mating system allows ruby-throated hummingbirds to maximize their reproductive success during Pennsylvania’s relatively short breeding season.
The female takes sole responsibility for nest construction, incubation, and chick rearing. She builds an intricate nest using plant fibers, spider silk, and lichens, typically positioned on a thin branch 5 to 30 feet above ground. Age of young at first flight about 20-22 days. Usually 1-2 broods per year, sometimes 3. Female may begin building second nest while still feeding young in the first.
Did You Know? Ruby-throated hummingbirds can beat their wings up to 80 times per second during regular flight and up to 200 times per second during courtship dives, creating the characteristic humming sound that gives them their name.
Migration Timing and Patterns
Understanding when hummingbirds arrive in Pennsylvania helps backyard enthusiasts prepare feeders and gardens for their arrival. Pennsylvanians, however, will have to wait a bit longer – late April for the southern part of the state and the beginning of May for the northern part. Male ruby-throated hummingbirds usually arrive several weeks before the females. This staggered arrival pattern creates excitement for birders who eagerly await the first sightings of the season.
By Late April they reach Nebraska, Iowa, Ohio, Pennsylvania, New York, New Jersey, and parts of New England. This timing coincides with the emergence of native flowering plants that provide crucial nectar sources for these early arrivals.
Preferred Habitats in Pennsylvania
During the breeding season, ruby-throated hummingbirds are found in deciduous and mixed deciduous-coniferous forests, woodland clearings and edges, parks, and suburban gardens. They often are found near water. Pennsylvania’s diverse landscape provides ideal habitat for these adaptable birds, from the Appalachian forests to suburban neighborhoods.
The species thrives in edge habitats where forests meet open areas, creating the perfect combination of nesting sites and feeding opportunities. This preference explains why many Pennsylvania residents successfully attract ruby-throated hummingbirds to their yards, especially those located near wooded areas or parks.
Pro Tip: To maximize your chances of attracting ruby-throated hummingbirds, position feeders near natural perching spots like thin branches or garden stakes, allowing these territorial birds to survey their domain between feeding sessions.
Rare Visitors: Western Hummingbirds in Pennsylvania
While ruby-throated hummingbirds dominate Pennsylvania’s hummingbird landscape, several western species occasionally venture into the state, creating exciting opportunities for dedicated birders and contributing to the broader picture of hummingbird species in Pennsylvania.
Rufous Hummingbird

The rufous hummingbird represents the most likely rare visitor among Pennsylvania’s vagrant hummingbird species. These small but aggressive birds typically breed in the Pacific Northwest but increasingly appear in eastern states during their southward migration.
Identification Features
- Males: Bright orange-red (rufous) coloration covering most of the body
- Females: Green backs with rufous sides and tail
- Slightly smaller than ruby-throated hummingbirds
- Distinctive rufous tail coloration in both sexes
When and Where to Look Most are Ruby Throats, with an occasional Rufous in the mix at the feeders. Rufous hummingbirds typically appear in Pennsylvania during late summer and fall migration, with most sightings occurring between August and October. They’re most commonly reported at established feeding stations that attract multiple hummingbirds.
Behavioral Differences Despite their small size, rufous hummingbirds are notably aggressive and will often dominate feeding stations, chasing away larger ruby-throated hummingbirds. This territorial behavior makes them easier to spot when present, as they tend to claim and defend prime feeding locations.
Calliope Hummingbird: The Tiny Treasure

The calliope hummingbird holds the distinction of being North America’s smallest breeding bird, making any Pennsylvania sighting particularly special for birders. These western mountain specialists rarely venture into eastern regions, but when they do, they create memorable experiences for fortunate observers.
Distinctive Characteristics
- Smallest North American hummingbird (2.5-3 inches)
- Males: Distinctive magenta throat streaks on white background
- Females: Peach-colored flanks with white underparts
- Compact, petite appearance compared to ruby-throated hummingbirds
Habitat and Behavior They prefer habitats with dense vegetation, including forests, shrublands, and grasslands. Nectar is the main component of their diet, supplemented with small insects and spiders. When calliope hummingbirds do appear in Pennsylvania, they’re often found in areas with diverse flowering plants and multiple food sources.
Allen’s Hummingbird

Allen’s hummingbirds occasionally appear in Pennsylvania during late fall migration, typically after most ruby-throated hummingbirds have departed for their wintering grounds. These Pacific Coast residents sometimes wander eastward, creating identification challenges for birders.
Key Identification Points
- Males: Orange-red throat and crown, green back
- Females: Difficult to distinguish from female rufous hummingbirds
- Slightly larger than rufous hummingbirds
- Often requires expert identification due to similarity with rufous species
Migration Timing Allen’s hummingbirds typically appear in Pennsylvania during November and December, well after the peak hummingbird season. Their late arrival often coincides with the first frost, making their presence even more remarkable.
Black-chinned Hummingbird

The black-chinned hummingbird represents the rarest hummingbird species recorded in Pennsylvania, with only a handful of confirmed sightings over the past several decades. These western birds typically remain in mountainous regions of the American West.
Identification Challenges
- Males: Black throat with narrow purple band at base
- Females: Nearly identical to female ruby-throated hummingbirds
- Requires careful observation and often photographic documentation
- Expert identification usually necessary for confirmation
Reporting Rare Sightings If you suspect you’ve spotted a rare hummingbird species in Pennsylvania, document the sighting with photographs and detailed notes. Contact local birding organizations or submit your observation to eBird to contribute to scientific understanding of these vagrant species.
Pennsylvania Hummingbird Migration: Timing and Patterns
