The energy and excitement of shorebirds are incredible. They are entertaining to see and monitor due to their extravagant mating rituals and ferocious territory defense. Unfortunately, it might be challenging to recognize shorebirds. 

California has the third-longest coastline in the US, at 840 miles. In addition to enjoying California’s sunny beaches, birdwatchers have a great opportunity to see dozens of magnificent seabirds.

To learn more about these wonderful creatures, keep reading. These birds are well-adjusted to nesting and thriving in coastal areas.

1. Heermann’s Gull

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Charadriiformes
  • Genus: Larus
  • Species: Larus heermanni
  • Length: Between 18.1 and 20.9 inches
  • Weight: Between 13.1 and 22.7 ounces
  • Wingspan: Between 40.9 and 45.3 inches

California is home to the Heermann’s gull during the summer months of June through September. It features a white head, a bright red bill, and a gray body, with a pale gray underside. It is simple to recognize from other gulls, thanks to its white head.

It snatches the brown pelican’s catch and is frequently spotted with flights of terns and other gulls. This bird typically catches fish in flight and feeds on fish, crabs, marine invertebrates, and lizards.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Charadriiformes
  • Genus: Tringa
  • Species: Tringa semipalmata
  • Length: Between 13 and 16.1 inches
  • Weight: Between 7 and 11.6 ounces
  • Wingspan: About 27 inches

During willet’s non-breeding season, California is its winter home. The shorebird is robust and stocky, with gray or brown feathers and white and black wing stripes. The feathers start to mottle in the summer.

This bird can frequently be observed by itself exploring the stony shores in search of worms, crabs, and clams. It often constructs its nest close to the water’s edge and has a delicate bill tip that aids in foraging for food day and night. It may also be found near inland wetlands like marshes.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Charadriiformes
  • Genus: Haematopus
  • Species: Haematopus bachmani
  • Length: Between 16.5 and 18.5 inches
  • Weight: Between 17.6 and 24.7 ounces
  • Wingspan: Between 28 and 36 inches

California is home to the black oystercatcher, a year-round inhabitant with black plumage, an orange-red bill, with pale pink legs. It lives in the Channel Islands and loves to stay on stony coasts.

Despite its name, it rarely eats oysters and primarily consumes crabs, clams, and limpets. By severing the abductor muscle that keeps shells closed, it uses its powerful bill to break shells. It searches for prey by walking slowly at low tide. Looking closely, you can see this bird on flat, stony reefs. It also whistles a peculiar cry.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Suliformes
  • Genus: Urile
  • Species: Urile penicillatus
  • Length: About 34 inches
  • Weight: About 4.6 pounds
  • Wingspan: About 4 feet

The largest breeding colony of the Brandt’s cormorant, which has a breeding range that encompasses the whole Pacific Coast, is located on San Miguel Island within Channel Islands State Park. It is a black bird with bristly white feathers on the neck and shoulders and a vivid cobalt-blue throat. Large flocks of these birds typically graze together, frequently with seabirds and other aquatic creatures.

To capture fish and shellfish beneath underwater structures, they dive deeper than 200 feet. This seabird can be seen on the cliffs and offshore boulders. When it captures its victim, it uses its beak to crush it before swallowing it whole. This bird swims beneath the schools it targets to force the schools to the surface so they can be captured more easily.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Podicipediformes
  • Genus: Charadrius
  • Species: Aechmophorus occidentalis
  • Length: Between 22 and 30 inches
  • Weight: Between 1.7 and 4.4 pounds
  • Wingspan: Between 31 and 40 inches

Most western grebe’s face is black, with a striking transition from black to white around the neck. Its eyes are crimson, and its bill is yellowish-green. The bird walks awkwardly on earth because its feet are positioned far back. The western grebe is a year-round resident of California, but its population peaks from September to May.

Pairs of courting birds engage in a courtship ritual to entice females. This bird was frequently exploited in the 19th century to produce coats and caps due to its waterproof plumage. When it preens, it frequently swallows its feathers, which line the stomach and shield it from the jagged fish bones.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Charadriiformes
  • Genus: Uria
  • Species: Uria aalge
  • Length: Between 15 and 18 inches
  • Weight: Between 1.67 and 2.75 pounds
  • Wingspan: Between 24 and 29 inches

The common murre, also called the common guillemot, lives all year long in California, though the summer months are the most prevalent. The bird has a belly that is completely white and underparts that are blackish or brown. Although these two species are unrelated, it does appear something like a penguin.

The common murre often rests on the water’s surface between dives, in which it can dive as deep as 590 feet to capture prey. It has quick wing beats that may accelerate up to 50 mph and produce a noise resembling a helicopter. The female lays just one egg yearly, and common murres can identify their eggs by their distinctive markings.

Frequently Asked Questions

What Species of Birds Inhabit the Coast of California?

Plover types, pelicans, seabirds, loons, grebes, gulls, various shorebirds, and other bird species are among the bird species that can be seen on Southern California’s beaches. Sanderlings, which appear to glide back and forth across the beach sand as a wave breaks, are constantly amusing.

What Kind of Bird Is Famous in California?

The California quail, the state bird of California, has appeared in several Walt Disney films, including “Bambi,” and its nests may hold up to 28 eggs. These enormous clutches could result from females “dropping” eggs—a practice known as “egg-laying”—in nests more than their own.

What Is the Biggest and Rarest Flying Bird in California?

The Gymnogyps californianus, also known as the California condor, is one of the biggest avian species. This is one of the rarest and most threatened birds worldwide.

What Exactly Is a Coastal Bird?

Although they rely on the land for breeding, these birds are ocean birds because they make long flights to feed in the ocean, even during the breeding season. A majority of seagulls, terns, penguins, pelicans, cormorants and auks are examples. Oceanic organisms have evolved to live mostly in the marine environment.

What Is a Shorebird?

Charadriiformes, which includes shorebirds, sandpipers, gulls, avocets, oystercatchers, and phalaropes, is a diverse collection of avian species. There are over 217 identified species of shorebirds worldwide, 81 of which spend all or part of their lives in the Americas.

What Are the Names of the Small Birds on the Beach?

Little groups of silvery, pale shorebirds prowl along the water’s edge along the winter shorelines of the Pacific and Atlantic, ebbing and flowing with each wave. Sanderlings are the name for these little sandpipers.

What Shorebird Is the Most Prevalent?

Among the most common shorebirds is the sanderling.
