Category: 99th site of the Western Hemispheric Shorebird Reserve Network (WHSRN)

Bahía de Todos Santos was designated as the Western Hemispheric Shorebird Reserve Network’s 99th site in September 2017.

  • The site holds over 4% of the Pacific population of the nominate subspecies of snowy plover (Charadrius nivosus), which is considered threatened in both Mexico and the USA, and Near Threatened at a global level.
  • Bahía de Todos Santos regularly holds important numbers of the red knot (Calidris canutus roselaari), an endangered species in Mexico.
  • Other relevant species are the willet (Tringa semipalmata inornatus) and marbled godwit (Limosa fedoa).

The WHSRN sites are found in 15 countries and together they cover nearly 36.8 million acres of shorebird habitat across the Americas.

This designation project began in 2016 and Terra Peninsular worked together with the Commission for Environmental Cooperation (CEC) and CICESE.


Bahía de Todos Santos WHSRN site


Each year, millions of migratory birds fly through the American continent along the Pacific Flyway.

During migration, shorebirds arrive to staging areas to rest and feed. Many of these sites are important for their survival.

In that route, Bahía de Todos Santos, in Ensenada, México, is an important staging area for migratory birds, mainly the coastal area between Playa Hermosa and Estero de Punta Banda.

Bird migration

Migratory birds prefer beach habitats and migrate to breed or winter, they make two journeys each year: in the winter they migrate south, and in the spring they fly back to the north to breed.

In each journey, most of the bird fly more than 7,000 miles or even 15,000 miles.

What is WHSRN?

The Western Hemisphere Shorebird Reserve Network (WHRSN) is an international cooperation strategy to conserve and protect the habitat of shorebirds in the American continent.

This strategy seeks to involve local communities, authorities, civil and academic organizations to protect the habitat of shorebirds in the western hemisphere.
