The rusty blackbird (Euphagus carolinus) is a medium-sized blackbird found in North America. It gets its name from the rust-colored feathers on its head and body. Rusty blackbirds have a very distinct vocalization that helps identify them. In this article, we will explore the different sounds and songs rusty blackbirds make.
Rusty Blackbird Call
The most common vocalization of the rusty blackbird is a metallic “check” or “tchek” call. This call is often given in flight or when perched. It is a short, sharp sound that carries well. The call is distinct and helps distinguish rusty blackbirds from other similar blackbird species like the red-winged blackbird.
Here are some key facts about the rusty blackbird call:
- Sounds like: “check” or “tchek”
- Loud and metallic sounding
- Given frequently in flight and when perched
- Useful identifier for the species
- Can sound almost mechanical at times
The rusty blackbird’s call can be almost machine-like and robotic. It carries well through marshes and other wetland habitats where rusty blackbirds like to reside. Listen for this metallic “check” sound to locate and identify rusty blackbirds.
Rusty Blackbird Song
In addition to its call, the rusty blackbird has a unique song that is mostly heard during the breeding season. The song consists of squeaky notes and buzzy sounds. Here are some key details about the rusty blackbird song:
- Sounds like: A series of squeaky, buzzing notes
- Song sequence lasts 2-3 seconds
- Lower and more varied pitches than their call
- Used for courtship and mating communication
- Not especially melodious or musical to human ears
The rusty blackbird’s song has been described as “a confused jumble of notes and squeaks” by some birding guides. The notes cover a range of frequencies and lack a consistent melody. However, to other rusty blackbirds, this song signals an interested mate during breeding season.
When and Where to Hear Rusty Blackbirds
So when and where can you listen for rusty blackbirds? Here are some tips:
- Most vocal during breeding season from March-June
- Listen in wetland habitats like marshes, swamps, and wooded wetlands
- Northern tier of North America is their core range
- Dawn and dusk are often the most vocal times
- You may hear the check call year-round on migration
Your best chances to hear both the call and song of the rusty blackbird are during spring in their breeding habitat. However, anytime you are in an area frequented by rusty blackbirds, listen carefully for their distinct vocalizations.
Differences From Other Blackbirds
The call and song of the rusty blackbird help distinguish it from other similar blackbird species. Here are some key differences:
| Blackbird Species | Call/Song Differences |
|---|---|
| Red-winged blackbird | Has a melodious, liquid “conk-a-ree” song; check call is softer |
| Common grackle | Makes raspy, squeaky sounds; lacks metallic call |
| Yellow-headed blackbird | Call is scratchier; song is complex and musical |
As you can see, the rusty blackbird has a very distinct vocalization compared to other blackbirds. The key is listening for that loud, metallic “check” call and paying attention to their habitat.
Conservation Status
Understanding rusty blackbird vocalizations is important because this species is actually in decline. Rusty blackbird populations have dropped an alarming 85-95% in recent decades according to the Cornell Lab of Ornithology.
Habitat loss in their boreal forest breeding grounds is the major cause. Their wetland habitats are also threatened. Being able to identify rusty blackbirds by sound helps birders and scientists track populations and assess conservation status.

Conclusion
In summary, the rusty blackbird has a very unique call and song that help identify this species. Its common call is a loud, metallic “check” and its song is a jumble of squeaky, buzzing notes. Rusty blackbird populations have declined significantly in recent decades. Being able to recognize their vocalizations can help birders more accurately survey populations. With increased awareness and conservation action, hopefully the rusty blackbird’s unique sound will endure for generations to come. Let’s all try to get out and listen for these special birds!
