Bonaparte's Gull (immature)
Family: (Laridae) Gulls, Terns and Allies
Preferred Habitat: Coastal bays, beaches, marshes.
Seasonal Occurrence: Common in winter; uncommon fall and spring.
Notes: Bonaparte's Gull is an attractive small gull found primarily in winter in our area. It breeds in the boreal forests of Canada. Bonaparte's Gull is the only gull to nest in trees. Most Bonaparte's Gulls in Texas exhibit nonbreeding or immature plumage. One of the most striking identification marks is the large white triangular patches on the upper front parts of their wings. Adults in winter plumage and immatures are quite similar, but immatures have a black band on their tail tips and brownish black bands on their wings. Bonaparte's Gulls feed on fish, crustaceans, and insects. They do not eat garbage or carrion.
