Western Gull – Larus occidentalis
Gulls are a common sight at the beach. I discovered our California beaches have a species called Western Gull. They are scavengers. Picnics or snacks will be raided by these plucky birds if you’re not on guard.
They can be found at ocean beaches and marinas, especially near fish cleaning stations or harbor restaurants. Western Gulls’ average lifespan is 15 years. They often mate for life and their offspring mature at four years. Their clutch each breeding season is one to three eggs. The male and female share incubating duties and feeding their chicks.
SIZE:
Length: 22.1-26.0 in (56-66 cm)
Weight: 28.2-44.1 oz (800-1250 g)
Wingspan: 47.2-56.7 in (120-144 cm)

APPEARANCE:
Mature adults have a white body, dark gray or black backs and upper wings. They have a red spot on their beak which means they are of breeding age. The spot gets brighter during breeding season. Also, chicks peck the red spot to be fed and the adult regurgitates food for them.

These gulls were hanging out at surf camp for kids. They probably learned that snacks might be left or dropped.
FOOD:
The gull has been known to eats birds, eggs, nestlings, fish, invertebrates and decomposing carcasses. If food is not readily available at the sea, they may visit dumps and eat trash. They catch their food while flying, swimming or walking along the shore.

NESTING:
Both male and female will scrape out a nest near a windbreak like a rock or driftwood. Or they may nest in rocky shores where their nest will be hidden from predators. Their nests are about 12 inches across with the inside bowl six inches across. The Western Gulls line their nest with grasses, seaweed, weeds and feathers.
SOUNDS:

I have seen video of gulls flying by and grabbing food from people, to be honest, that make me mad. But, the humans are at fault! 😂 There is no such thing as a Sea Gull…
I’ve seen them attack beach bags. digging in for food.
Interesting read. Thanks for improving my bird brain.
Ha! I’m learning so much with this Bird of the Week challenge, too.
I don’t miss the gulls too much! We do have our own here though- the Ring Billed Gull. They are at the reservoirs and of course anywhere they can scavenge food. Their heads and feather patterns are different though.
That’s interesting! I wouldn’t expect gulls in Colorado.
