Rufous Vs Ruby Throated Hummingbird

Although these species rarely overlap, they might stay in the same area during their migration. If you’re confused about what kind of visitors you’re getting on your feeders, here’s the list of Rufous vs Ruby Throated hummingbird differences.

1. Color

The Rufous hummingbird has a specific brown and orange, a rust-like color that no other hummingbird has. The male has white chest feathers under the orange and green gorget. The female also has some orange hues, but her throat is speckled with green dots.

The Ruby-throated hummingbird has a fork-like tail, while the Rufous hummingbird has a more round tail. The best time you can notice the difference is when the birds are perched or mid-flight.

3. Size

4. Location

Location is the key clue – the breeding territories of these species do not overlap. The Rufous nests from Oregon and up north, while the Ruby-throated hummingbird stays in the east part of North America.

They might overlap on one occasion during their migration to Central America.

5. Migration

Some ruby-throated hummingbirds are known to spend the winters in the US, migrating to Florida to enjoy the warmer winters. Unlike them, all Rufous hummingbirds leave North America by the end of October, so it’s impossible to spot a Rufous hummingbird during the winter.

6. Sound

Sound is another, not as noticeable, difference between rufous vs ruby throated hummingbird. The ruby-throated hummingbird is louder, often chirping for no apparent reason. They also fly faster, so the buzz or hum is more noticeable.

Rufous hummingbirds release loud noises only when they’re threatened or want to chase away another bird.

Bottom Line: Rufous Vs Ruby Throated Hummingbird

Telling apart Rufous vs Ruby Throated hummingbird is much harder for beginners due to the similar size of both birds. While the females of these kinds are much alike, the males have distinct yet vivid colors that make them easier to distinguish.

They prefer to spend the season in different parts of North America, so it’s harder to spot them side by side. On a rare occasion, during the fall migration, these hummingbirds can be spotted together. However, the Rufous is much more aggressive and will chase off other hummingbirds.
