A Jewel of the Desert and a Delight for Nature Lovers
Nestled between the Sea of Cortez and the arid mountains of Baja California Sur, La Paz is a haven for biodiversity. While visitors often come seeking whale sharks, sea lions, and the turquoise bays of Balandra and Espiritu Santo Island, there’s a smaller but equally captivating resident that deserves attention: the Costa’s Hummingbird (Calypte costae).

With its dazzling iridescent plumage and remarkable agility, the Costa’s Hummingbird offers a magical glimpse into Baja’s desert wildlife. This blog post will explore everything you need to know about spotting and appreciating this tiny desert jewel—and how ecotourism with local guides like those at Eco Migrations provides a respectful and rewarding way to experience it.
What Makes Costa’s Hummingbird Special?
Costa’s Hummingbird is one of the smallest and most visually striking hummingbirds found in North America. Males boast a radiant purple crown and throat, forming a shimmering “moustache” that flares in the sunlight. Females and juveniles are less vivid but still elegant, with soft green backs and pale underbellies.
Unlike many tropical hummingbirds that dwell in lush rainforests, Costa’s Hummingbirds have evolved to thrive in arid, desert-like environments—making Baja California Sur one of their prime habitats. They are uniquely adapted to survive hot temperatures, sparse vegetation, and limited water sources.
Where to Find Costa’s Hummingbirds in La Paz
Costa’s Hummingbirds are year-round residents in Baja California Sur. In La Paz, you can often spot them:
- In native desert scrublands around the city outskirts
- In the cacti and acacias of El Centenario and El Comitán
- Near gardens and flowering plants around the Malecon, local parks, and eco-lodges
- On nature tours around Espiritu Santo Island and Balandra, especially where native vegetation flourishes
If you’re hoping for the best chance to observe these birds, join an early morning ecotour led by naturalist guides. At Eco Migrations, we know the best spots and the quietest times to observe Costa’s Hummingbirds without disturbing their natural behaviors.
Behavior and Feeding of Costa’s Hummingbirds
Costa’s Hummingbirds are nectar feeders, relying on native desert flowers like chuparosa, ocotillo, and agave. Their long, specialized tongues allow them to drink while hovering mid-air. They’re also aggressive defenders of feeding territories, often chasing away larger birds or other hummingbirds.
In addition to nectar, they eat small insects and spiders, which provide vital protein—especially during the breeding season. Watch them closely, and you might witness their quick, darting movements as they pluck tiny bugs from leaves or catch gnats mid-flight.
Courtship and Nesting
Costa’s Hummingbirds are solitary and fiercely territorial, but the males put on an unforgettable show during courtship. They climb high into the air and dive downward in a fast U-shaped arc, producing a high-pitched sound with their wings or tail feathers as they swoop past the female.
Nests are tiny, cup-shaped structures made from plant fibers, spider silk, and lichens. Females build them on low branches or shrubs and typically lay two pea-sized eggs. During the roughly two-week incubation period, the female tends to the nest alone.
Breeding season in Baja generally peaks between February and April, although nesting may occur outside these months depending on food availability and weather conditions.
Why They Matter: The Role of Costa’s Hummingbirds in the Ecosystem of Baja California Sur
Despite their size, Costa’s Hummingbirds play a significant role in the desert ecosystem of Baja California Sur:
- They are important pollinators of native desert plants.
- Their foraging habits help sustain plant biodiversity in arid environments.
- They contribute to the natural balance of insects, particularly during breeding season.
By observing and protecting hummingbirds, we are also supporting a broader chain of ecological health in one of Mexico’s most delicate environments.
Conservation Status and Threats
Costa’s Hummingbirds are currently listed as Least Concern by the IUCN. However, their habitats are increasingly at risk from:
- Urban sprawl and habitat fragmentation
- Pesticide use
- Invasive plant species
- Climate change impacting bloom cycles and water availability
As ecotourism grows in La Paz, sustainable tourism practices are essential to protecting not only hummingbirds but the entire web of life that depends on Baja’s desert landscapes.
How to Ethically Observe Costa’s Hummingbirds
At Eco Migrations, we believe in responsible ecotourism that allows people to enjoy and learn from nature without disrupting it. When watching hummingbirds:
- Stay quiet and patient.
- Use binoculars instead of approaching too closely.
- Avoid using artificial feeders or bright flash photography.
- Support native plant growth wherever possible.
Our guided nature walks and paddleboarding tours often include stops for birdwatching, especially around Balandra’s mangroves or Espiritu Santo’s rugged coastline—both great spots to catch a glimpse of Costa’s Hummingbirds and other desert-adapted species.
Why Birdwatchers Love Baja
La Paz is a birdwatcher’s paradise, not only for hummingbirds but also for a range of other seabirds, shorebirds, and migratory species. The combination of marine and desert ecosystems creates an unusual biodiversity hotspot that offers something special year-round.
Costa’s Hummingbird is one of the most accessible and charismatic species, making it a perfect ambassador for bird tourism in Baja California Sur.
