Franklin's Gull (Larus pipixcan)--
This
gull is about 15 inches long. The wingspan is 36 inches. It is
similar to the Laughing Gull but smaller, lighter, with slate
gray wings with white bar and black-and-white tips on primaries.
All winter birds have a dark half-hood, more extensive than in
any winter Laughing Gull.
The voice is a loud, high-pitched ha-ha-ha-ha-ha-ha.
Laughing Gulls live mainly in prairie marshes and sloughs
in large, noisy colonies. They often feed on insects in plowed
fields. The eggs (3 buff-brown colored) are laid in a loose platform
in a marsh.
These gulls breed on prairie marshes from southern Canada
to South Dakota and Iowa; also in scattered marshes in the West.
They migrate to the southeast and winter mainly along the west
coast of South America.
