The smallest of North American terns (Sternula antillarum), the least tern migrates to the Ensenada coastline every spring to breed. Key facts about the local colonies include: [1, 2]
Primary Habitats: They build shallow, ground-level nests along open, sandy beaches and salt flats near wetlands.
Key Area: The Estero de Punta Banda south of Ensenada hosts one of the largest and most vital nesting colonies in Baja California, on some years boasting around 70 breeding pairs.
Seasonal Presence: They arrive in spring (late March to April) and stay to breed and rear their chicks through August.
🛑 How You Can Help
Because they nest directly on the sand, these birds are highly vulnerable to human foot traffic, off-road vehicles, and pets.
Respect the Fences: Conservation groups install temporary protective fencing at the nesting site at the end of the Spit. Always stay outside of these marked areas.
Keep Dogs Leashed: Off-leash dogs are a primary threat to nests and fragile chicks.
