Hummingbirds in Pennsylvania: Species to Know

 Last Reviewed by Jesse F. on 12-10-2024

There have been reports of nearly 30 different species of hummingbirds seen in the United States. Some of these are common can be found every year, while some are rare or accidental visitors. In Pennsylvania, there are two hummingbird species that are considered either common or semi-common, and four that are thought of as rare. This means there are a total of six hummingbird species you could possibly encounter in the state.

6 hummingbirds have been spotted in Pennsylvania

The 6 species of hummingbirds in Pennsylvania are the Ruby-throated hummingbird, Rufous Hummingbird, Black-chinned Hummingbird, Calliope Hummingbird, Allen’s Hummingbird, and the Anna’s Hummingbird.

Below we’ve put together a list of hummingbirds that can be seen in the state of Pennsylvania. For each species in this list you’ll find the species name, pictures of what it looks like, specifications about appearance, and where and when you may be able to spot them. We will list the 2 more common species first, and the 4 rare ones last. Thanks for reading!

Scientific name: Archilochus colubris

Ruby-throated hummingbirds are the most common hummingbirds in the eastern half of the United States. They have a green back and white underparts. Males have a ruby red throat that can look black in certain lighting.

Each spring they enter the country in droves from their wintering grounds in Central America. Many of them fly over the Gulf of Mexico in one non-stop flight! Ruby-throated hummingbirds are fairly easy to attract to backyards with nectar feeders and flowers.  

Ruby-throated hummingbirds are seen throughout Pennsylvania during the spring and summer months. They will arrive in April and May and leave in September.  


2. Rufous Hummingbird

Scientific name: Selasphorus rufus

Rufous hummingbirds are known for being very “feisty” when it comes to sharing feeders and chasing off other hummers. Males are orange all over with a white patch on the upper breast and an orange-red throat. Females are green with rusty patches and a speckled throat.

In the spring they migrate up through California, spend the summer in the Pacific northwest and Canada, then zip back down through the Rockies in the fall. While the rufous is considered a hummingbird of the western U.S., they are probably the second most commonly sighted species on the east coast after the ruby-throated hummingbird.

Recorded sightings in Pennsylvania tend to be most frequent in the eastern half of the state, and often during fall and winter.


3. Black-chinned Hummingbird

Scientific name: Archilochus alexandri

Black-chinned hummingbirds migrate north from Mexico and Central America each year and breed in the western United States. Males throat color looks plain black in most light, however they do have a small strip of purple feathers along the bottom that is sometimes visible. Females appear like most hummingbird females green above and pale below with a plain throat. They are widespread among many habitats from deserts to mountain forests and like to perch on bare branches. 

While they are a bird of the west coast, they have been spotted in most states along the east coast at least once, including Pennsylvania where there have been a few sightings over the years. They would still be considered rare for the state, but you may get lucky.  


4. Calliope Hummingbird

Calliope Hummingbird

Scientific name: Selasphorus calliope

The calliope hummingbird winters in Central America, then mainly spends its breeding season in the Pacific Northwest and parts of western Canada. That’s an impressively far migration, especially considering the calliope is the smallest bird in the United States!

Males have a unique throat pattern of magenta stripes that fork down on the sides. Females are plain with some green spotting on the throat and peachy tinted underparts.  

Calliope Hummingbirds are considered rare on the east coast, however they have been spotted in Pennsylvania a few times. 


5. Allen’s Hummingbird

Scientific name: Selasphorus sasin

These tiny guys fly all the way from Central America to breed along the Pacific Coast in California each year. They have very similar coloring to the Rufous hummingbird so it can be tricky distinguishing the two. Allen’s males are orange with a green back and orangey-red throat. Females have a speckled throat with dull green back and brownish-orange flanks. They migrate quite early compared to other hummingbirds, heading for California in January. 

Allen’s is rare for Pennsylvania, but they have been spotted a couple times, typically around the Philadelphia and Lancaster area. 


6. Anna’s Hummingbird

Scientific name: Calypte anna

Anna’s actually stay in the U.S. all year within most of their range, however you’ll only find them regularly in a few of the western states, including California. The green of their feathers tends to be a bit brighter and more iridescent than most others, and even their chest and belly are sprinkled with emerald feathers. Males have rosy-pink throats and those colorful feathers extend up onto their forehead. 

Anna’s very uncommon on the east coast, but they do stray from time to time. Only a few have been spotted in Pennsylvania over the years, in the southeastern corner of the state.
