|Franklin's Gull (Larus pipixcan)
Chilean name: Gaviota de Franklin
Franklin's Gull breeds in inland North America where it is found at lakes and marshes. During the northern winter it migrates to the Pacific coasts of Central and South America as far as south central Chile.
|In breeding plumage it has a black hood with white eye crescents and a bright red bill. In non-breeding plumage, seen here in photos 1 and 2, it has only a partial, greyish hood and the bill is black with a red tip. Note the distinctive wing pattern showing the contrast between the pale grey and the black wing-tips with small white windows.|
|Photos 3 and 4 show 1st winter birds where the grey back contrast with the brownish wings and the tail has a black subterminal band.|
