From the ubiquitous Anna’s Hummingbird defending your feeder to the rare vagrant species that send birders scrambling for their cameras, this guide reveals everything you need to know about these fascinating neighbors.
Anna’s Hummingbird
If you’ve ever seen a hummingbird in Southern California, chances are excellent it was an Anna’s Hummingbird. These year-round residents have adapted so well to urban environments that they’re often more common in cities than in wild habitats.
Key Identification Features:
- Males: Brilliant rose-red throat and crown that appears dark in poor light
- Females: Green back with spotted throat and white-tipped tail feathers
- Size: Medium-large for hummingbirds (4 inches long)
- Distinctive straight, black bill
Pro Tip: Male Anna’s Hummingbirds perform spectacular dive displays during breeding season, creating a distinctive “pop” sound at the bottom of their 130-foot dives.
Anna’s Hummingbirds have revolutionized their lifestyle around human-provided resources. They’re the species most likely to visit your feeders consistently, often establishing territories that include multiple yards. Unlike many hummingbird species that migrate, Anna’s brave Southern California’s mild winters, making them reliable year-round companions.
Where to Find Them:
- Urban gardens and parks
- Coastal areas with native plants
- Suburban neighborhoods with feeders
- Griffith Park and other urban green spaces
Allen’s Hummingbird
Allen’s Hummingbirds bring drama to Southern California’s coastal regions, particularly during their spring and summer breeding season. These coastal specialists prefer the maritime climate and the diverse flowering plants that thrive near the ocean.
Identification Challenges:
- Males: Orange-red throat, green back, rufous sides and tail
- Females: Nearly identical to female Rufous Hummingbirds
- Slightly smaller than Anna’s Hummingbirds
- Often confused with Rufous Hummingbirds (expert identification sometimes requires hand measurements)
Did You Know? Some Allen’s Hummingbirds have evolved into year-round residents along the California coast, while others maintain traditional migratory patterns. This makes them one of the most interesting species for studying hummingbird adaptation.
The California Native Plant Society emphasizes that Allen’s Hummingbirds particularly benefit from native coastal scrub plants, which provide both nectar and nesting materials.
Prime Locations:
- Coastal sage scrub habitats
- Lagoons and coastal parks
- Gardens with native California plants
- Areas from Santa Barbara to San Diego
Rufous Hummingbird
Don’t let their small size fool you – Rufous Hummingbirds pack an aggressive punch that’s legendary among birders. These spring and fall migrants turn Southern California into a battleground as they defend prime feeding territories during their epic journeys.
Behavioral Characteristics:
- Extremely territorial and aggressive
- Will chase birds twice their size away from feeders
- Travel up to 3,000 miles during migration
- Appear primarily during spring (March-May) and fall (July-September)
Field Marks:
- Males: Brilliant orange-red throat, rufous back and sides
- Females: Green back with rufous sides and tail base
- Relatively short, straight bill
- Rapid wingbeat creates distinctive buzzing sound
Migration Marvel: Research shows that Rufous Hummingbirds construct their cup-shaped nests using moss, spider silk, and feathers, positioning them strategically in temperate mountain forests during their travels. The Audubon Society describes them as “notably pugnacious” despite being among the smaller hummingbird species.
The key to attracting Rufous Hummingbirds lies in timing. Plant flowers that bloom during their migration periods, and be prepared for some serious feeder drama when they arrive.
Black-chinned Hummingbird
While coastal areas get most of the hummingbird attention, Black-chinned Hummingbirds prefer Southern California’s inland and desert regions during the warmer months. These adaptable birds have mastered the art of surviving in challenging environments.
