The
Yellow-footed Gull is a large gull species with a small geographic range,
nesting only in and around the Gulf of California and the Baja Peninsula.
In the United States, they are regular post-breeding visitors to the Salton
Sea in southern California, but total number of birds found in the United
States is typically quite small.
Habitat: Found near the shoreline in most seasons,
rarely venturing far out to sea. Found on open shorelines of the
Salton Sea when they visit the United States.
Diet: Feeds heavily on fish, but will also feed on
crustaceans, mollusks, marine worms, eggs and young birds, carrion, and
refuse.
Behavior: Foraging behavior depends upon food item
and location. They will walk in terrestrial habitats, swim on the
ocean's surface and pluck items near the surface, or sometimes will make
short plunges into the water.
Nesting: A colonial nester, the nest of a
Yellow-footed Gull is a shallow scrape on the ground, lined with seaweed and
other plant material, placed on a beach near the high tide line. The
female usually lays 3 eggs, and both parents help to incubate them.
When the eggs hatch, both parents help to raise the young. The young
fledge about 6 weeks after hatching.
Song: Has a steady, nasal voice, less harsh than
many gull species.
Migration: Considered a permanent resident in and
around the Gulf of California. Small numbers move northwards after breeding
season, reaching the Salton Sea in California.
Similar Species:
Similar to Western Gull, but leg color
differentiates the two species. The
Lesser Black-backed Gull also has a dark mantle and bright yellow legs,
but is considerably smaller with a less heavy bill.
Conservation Status: There are currently no
significant conservation concerns for the species, as populations are
relatively large and appear to be stable.
The IUCN lists the
Yellow-footed Gull as a species of "Least concern".
