Seabirds

 Bonaparte’s Gull, Chroicocephalus philadelphia 

Bonaparte’s Gulls nest in mixed forests near water bodies in Canada and Alaska. They primarily forage on insects and other small invertebrates during the breeding season. During winter, they migrate south to coastal regions of the United States, Mexico, and Central America, where they shift their diet to include small fish and aquatic invertebrates.

 American Herring Gulls, Larus smithsonianus 

American Herring Gulls typically nest and raise their young in coastal habitats such as rocky shores, sandy beaches, and offshore islands along the Atlantic and Gulf coasts of North America, breeding from northeastern Canada to the southeastern United States. They are opportunistic feeders and forage in habitats such as estuaries, intertidal zones, beaches, marshes for fish, crustaceans, mollusks, insects, marine invertebrates, and even small mammals and birds. They can also be observed scavenging in landfills and parking lots.

 Franklin’s Gulls, Leucophaeus pipixcan 

In North America, during the breeding season, Franklin’s gulls forage in wetlands, marshes, and the surrounding grasslands for insects, including grasshoppers, beetles, flies, and their larvae. In winter, Franklin’s Gulls migrate southward to estuaries, beaches, and mudflats in coastal regions of Central and South America where they forage for fish, crustaceans, mollusks, and other aquatic invertebrates.

 Glaucous-winged Gull, Larus glaucescens 

Glaucous-winged Gulls are highly adaptable and can exploit a wide range of food sources and habitats. They are known for their opportunistic feeding habits, and will scavenge for food as well. They are commonly seen feeding on carrion, garbage, and scraps in urban areas and at landfills.

 Forster’s Tern, Sterna forsteri 

Forster’s Terns dive into the water from flight to catch minnows, silversides, and killifish. They also feed on shrimp, crabs, aquatic insects, and occasionally small crustaceans. They nest in colonies, often with other species of terns, on sandy or gravelly islands, beaches, or salt marshes of the central and northern parts of North America.
